citizenship by birth describes the acquisition of citizenship based on place of birth, known as Jus soli, regardless of the citizenship of parents.
citizenship by descent only describes the acquisition of citizenship based on the principle of Jus sanguinis, or by descent, where at least one parent is a citizen of the state and being born within the territorial limits of the state is not required. The majority of countries adhere to this practice. In some cases, citizenship is conferred through the father or mother exclusively.
dual citizenship recognized indicates whether a state permits a citizen to simultaneously hold citizenship in another state. Many states do not permit dual citizenship and the voluntary acquisition of citizenship in another country is grounds for revocation of citizenship. Holding dual citizenship makes an individual legally obligated to more than one state and can negate the normal consular protections afforded to citizens outside their original country of citizenship.
residency requirement for naturalization lists the length of time an applicant is required to live in a state before applying for naturalization. In most countries citizenship can be acquired through the legal process of naturalization. The requirements for naturalization vary by state but generally include no criminal record, good health, economic wherewithal, and a period of authorized residency in the state. This time period can vary enormously among states and is often used to make the acquisition of citizenship difficult or impossible.
ten driest places on earth (average annual precipitation) describes the annual average precipitation measured in both millimeters and inches for selected countries with climate extremes.
ten wettest places on earth (average annual precipitation) describes the annual average precipitation measured in both millimeters and inches for selected countries with climate extremes.
ten coldest places on earth (lowest average monthly temperature) describes temperature measured in both degrees Celsius and Fahrenheit as well as the month of the year for selected countries with climate extremes.
ten hottest places on earth (highest average monthly temperature) describes the temperature measured both in degrees Celsius and Fahrenheit as well the month of the year for selected countries with climate extremes.
The main steps in creating a constitution and amending it usually include the following steps: proposal, drafting, legislative and/or executive branch review and approval, public referendum, and entry into law. In many countries this process is lengthy. Terms commonly used to describe constitutional changes are “amended,” “revised,” or “reformed.” In countries such as South Korea and Turkmenistan, sources differ as to whether changes are stated as new constitutions or are amendments/revisions to existing ones.
A few countries including Canada, Israel, and the UK have no single constitution document, but have various written and unwritten acts, statutes, common laws, and practices that, when taken together, describe a body of fundamental principles or established precedents as to how their countries are governed. Some special regions (Hong Kong, Macau) and countries (Oman, Saudi Arabia) use the term “basic law” instead of constitution.
A number of self-governing dependencies and territories such as the Cayman Islands, Bermuda, and Gibraltar (UK), Greenland and Faroe Islands (Denmark), Aruba, Curacao, and Sint Maarten (Netherlands), and Puerto Rico and the Virgin Islands (US) have their own constitutions.
total dependency ratio - The total dependency ratio is the ratio of combined youth population (ages 0-14) and elderly population (ages 65+) per 100 people of working age (ages 15-64). A high total dependency ratio indicates that the working-age population and the overall economy face a greater burden to support and provide social services for youth and elderly persons, who are often economically dependent.
youth dependency ratio - The youth dependency ratio is the ratio of the youth population (ages 0-14) per 100 people of working age (ages 15-64). A high youth dependency ratio indicates that a greater investment needs to be made in schooling and other services for children.
elderly dependency ratio - The elderly dependency ratio is the ratio of the elderly population (ages 65+) per 100 people of working age (ages 15-64). Increases in the elderly dependency ratio put added pressure on governments to fund pensions and healthcare.
potential support ratio - The potential support ratio is the number of working-age people (ages 15-64) per one elderly person (ages 65+). As a population ages, the potential support ratio tends to fall, meaning there are fewer potential workers to support the elderly.
The World Bank Group Doing Business project measures business regulations and enforcement mechanisms across economies and selected cities. The project evaluates domestic small and medium-size companies and measures the regulations applying to them through their life cycle. The project encourages economies to compete towards more efficient regulation; offers measurable benchmarks for reform; and serves as a resource for academics, journalists, private sector researchers and others interested in the business climate of each economy.

Acidification - the lowering of soil and water pH due to acid precipitation and deposition usually through precipitation; this process disrupts ecosystem nutrient flows and may kill freshwater fish and plants dependent on more neutral or alkaline conditions (see acid rain).
Acid rain - characterized as containing harmful levels of sulfur dioxide or nitrogen oxide; acid rain is damaging and potentially deadly to the earth's fragile ecosystems; acidity is measured using the pH scale where 7 is neutral, values greater than 7 are considered alkaline, and values below 5.6 are considered acid precipitation; note - a pH of 2.4 (the acidity of vinegar) has been measured in rainfall in New England.
Aerosol - a collection of airborne particles dispersed in a gas, smoke, or fog.
Afforestation - converting a bare or agricultural space by planting trees and plants; reforestation involves replanting trees on areas that have been cut or destroyed by fire.
Asbestos - a naturally occurring soft fibrous mineral commonly used in fireproofing materials and considered to be highly carcinogenic in particulate form.
Biodiversity - also biological diversity; the relative number of species, diverse in form and function, at the genetic, organism, community, and ecosystem level; loss of biodiversity reduces an ecosystem's ability to recover from natural or man-induced disruption.
Bio-indicators - a plant or animal species whose presence, abundance, and health reveal the general condition of its habitat.
Biomass - the total weight or volume of living matter in a given area or volume.
Carbon cycle - the term used to describe the exchange of carbon (in various forms, e.g., as carbon dioxide) between the atmosphere, ocean, terrestrial biosphere, and geological deposits.
Catchments - assemblages used to capture and retain rainwater and runoff; an important water management technique in areas with limited freshwater resources, such as Gibraltar.
DDT (dichloro-diphenyl-trichloro-ethane) - a colorless, odorless insecticide that has toxic effects on most animals; the use of DDT was banned in the US in 1972.
Defoliants - chemicals which cause plants to lose their leaves artificially; often used in agricultural practices for weed control, and may have detrimental impacts on human and ecosystem health.
Deforestation - the destruction of vast areas of forest (e.g., unsustainable forestry practices, agricultural and range land clearing, and the over exploitation of wood products for use as fuel) without planting new growth.
Desertification - the spread of desert-like conditions in arid or semi-arid areas, due to overgrazing, loss of agriculturally productive soils, or climate change.
Dredging - the practice of deepening an existing waterway; also, a technique used for collecting bottom-dwelling marine organisms (e.g., shellfish) or harvesting coral, often causing significant destruction of reef and ocean-floor ecosystems.
Drift-net fishing - done with a net, miles in extent, that is generally anchored to a boat and left to float with the tide; often results in an over harvesting and waste of large populations of non-commercial marine species (by-catch) by its effect of"sweeping the ocean clean."
Ecosystems - ecological units comprised of complex communities of organisms and their specific environments.
Effluents - waste materials, such as smoke, sewage, or industrial waste which are released into the environment, subsequently polluting it.
Endangered species - a species that is threatened with extinction either by direct hunting or habitat destruction.
Freshwater - water with very low soluble mineral content; sources include lakes, streams, rivers, glaciers, and underground aquifers.
Greenhouse gas - a gas that"traps" infrared radiation in the lower atmosphere causing surface warming; water vapor, carbon dioxide, nitrous oxide, methane, hydrofluorocarbons, and ozone are the primary greenhouse gases in the Earth's atmosphere.
Groundwater - water sources found below the surface of the earth often in naturally occurring reservoirs in permeable rock strata; the source for wells and natural springs.
Highlands Water Project - a series of dams constructed jointly by Lesotho and South Africa to redirect Lesotho's abundant water supply into a rapidly growing area in South Africa; while it is the largest infrastructure project in southern Africa, it is also the most costly and controversial; objections to the project include claims that it forces people from their homes, submerges farmlands, and squanders economic resources.
Inuit Circumpolar Conference (ICC) - represents the roughly 150,000 Inuits of Alaska, Canada, Greenland, and Russia in international environmental issues; a General Assembly convenes every three years to determine the focus of the ICC; the most current concerns are long-range transport of pollutants, sustainable development, and climate change.
Metallurgical plants - industries which specialize in the science, technology, and processing of metals; these plants produce highly concentrated and toxic wastes which can contribute to pollution of ground water and air when not properly disposed.
Noxious substances - injurious, very harmful to living beings.
Overgrazing - the grazing of animals on plant material faster than it can naturally regrow leading to the permanent loss of plant cover, a common effect of too many animals grazing limited range land.
Ozone shield - a layer of the atmosphere composed of ozone gas (O3) that resides approximately 25 miles above the Earth's surface and absorbs solar ultraviolet radiation that can be harmful to living organisms.
Poaching - the illegal killing of animals or fish, a great concern with respect to endangered or threatened species.
Pollution - the contamination of a healthy environment by man-made waste.
Potable water - water that is drinkable, safe to be consumed.
Salination - the process through which fresh (drinkable) water becomes salt (undrinkable) water; hence, desalination is the reverse process; also involves the accumulation of salts in topsoil caused by evaporation of excessive irrigation water, a process that can eventually render soil incapable of supporting crops.
Siltation - occurs when water channels and reservoirs become clotted with silt and mud, a side effect of deforestation and soil erosion.
Slash-and-burn agriculture - a rotating cultivation technique in which trees are cut down and burned in order to clear land for temporary agriculture; the land is used until its productivity declines at which point a new plot is selected and the process repeats; this practice is sustainable while population levels are low and time is permitted for regrowth of natural vegetation; conversely, where these conditions do not exist, the practice can have disastrous consequences for the environment.
Soil degradation - damage to the land's productive capacity because of poor agricultural practices such as the excessive use of pesticides or fertilizers, soil compaction from heavy equipment, or erosion of topsoil, eventually resulting in reduced ability to produce agricultural products.
Soil erosion - the removal of soil by the action of water or wind, compounded by poor agricultural practices, deforestation, overgrazing, and desertification.
Ultraviolet (UV) radiation - a portion of the electromagnetic energy emitted by the sun and naturally filtered in the upper atmosphere by the ozone layer; UV radiation can be harmful to living organisms and has been linked to increasing rates of skin cancer in humans.
Waterborne diseases - those in which bacteria survive in, and are transmitted through, water; always a serious threat in areas with an untreated water supply.
The executive branches in approximately 80% of the world's countries have separate chiefs of state and heads of government; for the remainder, the chief of state is also the head of government, such as in Argentina, Kenya, the Philippines, the US, and Venezuela. Chiefs of state in just over 100 countries are directly elected, most by majority popular vote; those in another 55 are indirectly elected by their national legislatures, parliaments, or electoral colleges. Another 29 countries have a monarch as the chief of state. In dependencies, territories, and collectivities of sovereign countries - except those of the US - representatives are appointed to serve as chiefs of state.
Heads of government in the majority of countries are appointed either by the president or the monarch or selected by the majority party in the legislative body. Excluding countries where the chief of state is also head of government, in only a few countries is the head of government directly elected through popular vote.
Most of the world's countries have cabinets, the majority of which are appointed by the chief of state or prime minister, many in consultation with each other or with the legislature. Cabinets in only about a dozen countries are elected solely by their legislative bodies.
household consumption consists of expenditures by resident households, and by nonprofit institutions that serve households, on goods and services that are consumed by individuals. This includes consumption of both domestically produced and foreign goods and services.
government consumption consists of government expenditures on goods and services. These figures exclude government transfer payments, such as interest on debt, unemployment, and social security, since such payments are not made in exchange for goods and services supplied.
investment in fixed capital consists of total business spending on fixed assets, such as factories, machinery, equipment, dwellings, and inventories of raw materials, which provide the basis for future production. It is measured gross of the depreciation of the assets, i.e., it includes investment that merely replaces worn-out or scrapped capital. Earlier editions of The World Factbook referred to this concept as Investment (gross fixed) and that data now have been moved to this new field.
investment in inventories consists of net changes to the stock of outputs that are still held by the units that produce them, awaiting further sale to an end user, such as automobiles sitting on a dealer’s lot or groceries on the store shelves. This figure may be positive or negative. If the stock of unsold output increases during the relevant time period, investment in inventories is positive, but, if the stock of unsold goods declines, it will be negative. Investment in inventories normally is an early indicator of the state of the economy. If the stock of unsold items increases unexpectedly – because people stop buying - the economy may be entering a recession; but if the stock of unsold items falls - and goods "go flying off the shelves" - businesses normally try to replace those stocks, and the economy is likely to accelerate.
exports of goods and services consist of sales, barter, gifts, or grants of goods and services from residents to nonresidents.
imports of goods and services consist of purchases, barter, or receipts of gifts, or grants of goods and services by residents from nonresidents. Exports are treated as a positive item, while imports are treated as a negative item. In a purely accounting sense, imports have no direct impact on GDP, which only measures output of the domestic economy. Imports are entered as a negative item to offset the fact that the expenditure figures for consumption, investment, government, and exports also include expenditures on imports. These imports contribute directly to foreign GDP but only indirectly to domestic GDP. Because of this negative offset for imports of goods and services, the sum of the other five items, excluding imports, will always total more than 100 percent of GDP. A surplus of exports of goods and services over imports indicates an economy is investing abroad, while a deficit indicates an economy is borrowing from abroad.
Absolute monarchy - a form of government where the monarch rules unhindered, i.e., without any laws, constitution, or legally organized opposition.
Anarchy - a condition of lawlessness or political disorder brought about by the absence of governmental authority.
Authoritarian - a form of government in which state authority is imposed onto many aspects of citizens' lives.
Commonwealth - a nation, state, or other political entity founded on law and united by a compact of the people for the common good.
Communist - a system of government in which the state plans and controls the economy and a single - often authoritarian - party holds power; state controls are imposed with the elimination of private ownership of property or capital while claiming to make progress toward a higher social order in which all goods are equally shared by the people (i.e., a classless society).
Confederacy (Confederation) - a union by compact or treaty between states, provinces, or territories, that creates a central government with limited powers; the constituent entities retain supreme authority over all matters except those delegated to the central government.
Constitutional - a government by or operating under an authoritative document (constitution) that sets forth the system of fundamental laws and principles that determines the nature, functions, and limits of that government.
Constitutional democracy - a form of government in which the sovereign power of the people is spelled out in a governing constitution.
Constitutional monarchy - a system of government in which a monarch is guided by a constitution whereby his/her rights, duties, and responsibilities are spelled out in written law or by custom.
Democracy - a form of government in which the supreme power is retained by the people, but which is usually exercised indirectly through a system of representation and delegated authority periodically renewed.
Democratic republic - a state in which the supreme power rests in the body of citizens entitled to vote for officers and representatives responsible to them.
Dictatorship - a form of government in which a ruler or small clique wield absolute power (not restricted by a constitution or laws).
Ecclesiastical - a government administrated by a church.
Emirate - similar to a monarchy or sultanate, but a government in which the supreme power is in the hands of an emir (the ruler of a Muslim state); the emir may be an absolute overlord or a sovereign with constitutionally limited authority.
Federal (Federation) - a form of government in which sovereign power is formally divided - usually by means of a constitution - between a central authority and a number of constituent regions (states, colonies, or provinces) so that each region retains some management of its internal affairs; differs from a confederacy in that the central government exerts influence directly upon both individuals as well as upon the regional units.
Federal republic - a state in which the powers of the central government are restricted and in which the component parts (states, colonies, or provinces) retain a degree of self-government; ultimate sovereign power rests with the voters who chose their governmental representatives.
Islamic republic - a particular form of government adopted by some Muslim states; although such a state is, in theory, a theocracy, it remains a republic, but its laws are required to be compatible with the laws of Islam.
Maoism - the theory and practice of Marxism-Leninism developed in China by Mao Zedong (Mao Tse-tung), which states that a continuous revolution is necessary if the leaders of a communist state are to keep in touch with the people.
Marxism - the political, economic, and social principles espoused by 19th century economist Karl Marx; he viewed the struggle of workers as a progression of historical forces that would proceed from a class struggle of the proletariat (workers) exploited by capitalists (business owners), to a socialist"dictatorship of the proletariat," to, finally, a classless society - Communism.
Marxism-Leninism - an expanded form of communism developed by Lenin from doctrines of Karl Marx; Lenin saw imperialism as the final stage of capitalism and shifted the focus of workers' struggle from developed to underdeveloped countries.
Monarchy - a government in which the supreme power is lodged in the hands of a monarch who reigns over a state or territory, usually for life and by hereditary right; the monarch may be either a sole absolute ruler or a sovereign - such as a king, queen, or prince - with constitutionally limited authority.
Oligarchy - a government in which control is exercised by a small group of individuals whose authority generally is based on wealth or power.
Parliamentary democracy - a political system in which the legislature (parliament) selects the government - a prime minister, premier, or chancellor along with the cabinet ministers - according to party strength as expressed in elections; by this system, the government acquires a dual responsibility: to the people as well as to the parliament.
Parliamentary government (Cabinet-Parliamentary government) - a government in which members of an executive branch (the cabinet and its leader - a prime minister, premier, or chancellor) are nominated to their positions by a legislature or parliament, and are directly responsible to it; this type of government can be dissolved at will by the parliament (legislature) by means of a no confidence vote or the leader of the cabinet may dissolve the parliament if it can no longer function.
Parliamentary monarchy - a state headed by a monarch who is not actively involved in policy formation or implementation (i.e., the exercise of sovereign powers by a monarch in a ceremonial capacity); true governmental leadership is carried out by a cabinet and its head - a prime minister, premier, or chancellor - who are drawn from a legislature (parliament).
Presidential - a system of government where the executive branch exists separately from a legislature (to which it is generally not accountable).
Republic - a representative democracy in which the people's elected deputies (representatives), not the people themselves, vote on legislation.
Socialism - a government in which the means of planning, producing, and distributing goods is controlled by a central government that theoretically seeks a more just and equitable distribution of property and labor; in actuality, most socialist governments have ended up being no more than dictatorships over workers by a ruling elite.
Sultanate - similar to a monarchy, but a government in which the supreme power is in the hands of a sultan (the head of a Muslim state); the sultan may be an absolute ruler or a sovereign with constitutionally limited authority.
Theocracy - a form of government in which a Deity is recognized as the supreme civil ruler, but the Deity's laws are interpreted by ecclesiastical authorities (bishops, mullahs, etc.); a government subject to religious authority.
Totalitarian - a government that seeks to subordinate the individual to the state by controlling not only all political and economic matters, but also the attitudes, values, and beliefs of its population.
Cannabis (Cannabis sativa) is the common hemp plant, which provides hallucinogens with some sedative properties, and includes marijuana (pot, Acapulco gold, grass, reefer), tetrahydrocannabinol (THC, Marinol), hashish (hash), and hashish oil (hash oil).
Coca (mostly Erythroxylum coca) is a bush with leaves that contain the stimulant used to make cocaine. Coca is not to be confused with cocoa, which comes from cacao seeds and is used in making chocolate, cocoa, and cocoa butter.
Cocaine is a stimulant derived from the leaves of the coca bush.
Depressants (sedatives) are drugs that reduce tension and anxiety and include chloral hydrate, barbiturates (Amytal, Nembutal, Seconal, phenobarbital), benzodiazepines (Librium, Valium), methaqualone (Quaalude), glutethimide (Doriden), and others (Equanil, Placidyl, Valmid).
Drugs are any chemical substances that effect a physical, mental, emotional, or behavioral change in an individual.
Drug abuse is the use of any licit or illicit chemical substance that results in physical, mental, emotional, or behavioral impairment in an individual.
Hallucinogens are drugs that affect sensation, thinking, self-awareness, and emotion. Hallucinogens include LSD (acid, microdot), mescaline and peyote (mexc, buttons, cactus), amphetamine variants (PMA, STP, DOB), phencyclidine (PCP, angel dust, hog), phencyclidine analogues (PCE, PCPy, TCP), and others (psilocybin, psilocyn).

Mandrax is a trade name for methaqualone, a pharmaceutical depressant.
Marijuana is the dried leaf of the cannabis or hemp plant (Cannabis sativa).
Methaqualone is a pharmaceutical depressant, referred to as mandrax in Southwest Asia and Africa.
Narcotics are drugs that relieve pain, often induce sleep, and refer to opium, opium derivatives, and synthetic substitutes. Natural narcotics include opium (paregoric, parepectolin), morphine (MS-Contin, Roxanol), codeine (Tylenol with codeine, Empirin with codeine, Robitussin AC), and thebaine. Semisynthetic narcotics include heroin (horse, smack), and hydromorphone (Dilaudid). Synthetic narcotics include meperidine or Pethidine (Demerol, Mepergan), methadone (Dolophine, Methadose), and others (Darvon, Lomotil).
Opium is the brown, gummy exudate of the incised, unripe seedpod of the opium poppy.
Opium poppy (Papaver somniferum) is the source for the natural and semisynthetic narcotics.
Poppy straw is the entire cut and dried opium poppy-plant material, other than the seeds. Opium is extracted from poppy straw in commercial operations that produce the drug for medical use.
Qat (kat, khat) is a stimulant from the buds or leaves of Catha edulis that is chewed or drunk as tea.
Quaaludes is the North American slang term for methaqualone, a pharmaceutical depressant.
Stimulants are drugs that relieve mild depression, increase energy and activity, and include cocaine (coke, snow, crack), amphetamines (Desoxyn, Dexedrine), ephedrine, ecstasy (clarity, essence, doctor, Adam), phenmetrazine (Preludin), methylphenidate (Ritalin), and others (Cylert, Sanorex, Tenuate).
Civil Law - The most widespread type of legal system in the world, applied in various forms in approximately 150 countries. Also referred to as European continental law, the civil law system is derived mainly from the Roman Corpus Juris Civilus, (Body of Civil Law), a collection of laws and legal interpretations compiled under the East Roman (Byzantine) Emperor Justinian I between A.D. 528 and 565. The major feature of civil law systems is that the laws are organized into systematic written codes. In civil law the sources recognized as authoritative are principally legislation - especially codifications in constitutions or statutes enacted by governments - and secondarily, custom. The civil law systems in some countries are based on more than one code.
Common Law - A type of legal system, often synonymous with"English common law," which is the system of England and Wales in the UK, and is also in force in approximately 80 countries formerly part of or influenced by the former British Empire. English common law reflects Biblical influences as well as remnants of law systems imposed by early conquerors including the Romans, Anglo-Saxons, and Normans. Some legal scholars attribute the formation of the English common law system to King Henry II (r.1154-1189). Until the time of his reign, laws customary among England's various manorial and ecclesiastical (church) jurisdictions were administered locally. Henry II established the king's court and designated that laws were "common" to the entire English realm. The foundation of English common law is "legal precedent" - referred to as stare decisis, meaning "to stand by things decided." In the English common law system, court judges are bound in their decisions in large part by the rules and other doctrines developed - and supplemented over time - by the judges of earlier English courts.
Customary Law - A type of legal system that serves as the basis of, or has influenced, the present-day laws in approximately 40 countries - mostly in Africa, but some in the Pacific islands, Europe, and the Near East. Customary law is also referred to as"primitive law," "unwritten law," "indigenous law," and "folk law." There is no single history of customary law such as that found in Roman civil law, English common law, Islamic law, or the Napoleonic Civil Code. The earliest systems of law in human society were customary, and usually developed in small agrarian and hunter-gatherer communities. As the term implies, customary law is based upon the customs of a community. Common attributes of customary legal systems are that they are seldom written down, they embody an organized set of rules regulating social relations, and they are agreed upon by members of the community. Although such law systems include sanctions for law infractions, resolution tends to be reconciliatory rather than punitive. A number of African states practiced customary law many centuries prior to colonial influences. Following colonization, such laws were written down and incorporated to varying extents into the legal systems imposed by their colonial powers.
European Union Law - A sub-discipline of international law known as"supranational law" in which the rights of sovereign nations are limited in relation to one another. Also referred to as the Law of the European Union or Community Law, it is the unique and complex legal system that operates in tandem with the laws of the 27 member states of the European Union (EU). Similar to federal states, the EU legal system ensures compliance from the member states because of the Union's decentralized political nature. The European Court of Justice (ECJ), established in 1952 by the Treaty of Paris, has been largely responsible for the development of EU law. Fundamental principles of European Union law include: subsidiarity - the notion that issues be handled by the smallest, lowest, or least centralized competent authority; proportionality - the EU may only act to the extent needed to achieve its objectives; conferral - the EU is a union of member states, and all its authorities are voluntarily granted by its members; legal certainty - requires that legal rules be clear and precise; and precautionary principle - a moral and political principle stating that if an action or policy might cause severe or irreversible harm to the public or to the environment, in the absence of a scientific consensus that harm would not ensue, the burden of proof falls on those who would advocate taking the action.
French Law - A type of civil law that is the legal system of France. The French system also serves as the basis for, or is mixed with, other legal systems in approximately 50 countries, notably in North Africa, the Near East, and the French territories and dependencies. French law is primarily codified or systematic written civil law. Prior to the French Revolution (1789-1799), France had no single national legal system. Laws in the northern areas of present-day France were mostly local customs based on privileges and exemptions granted by kings and feudal lords, while in the southern areas Roman law predominated. The introduction of the Napoleonic Civil Code during the reign of Napoleon I in the first decade of the 19th century brought major reforms to the French legal system, many of which remain part of France's current legal structure, though all have been extensively amended or redrafted to address a modern nation. French law distinguishes between"public law" and "private law." Public law relates to government, the French Constitution, public administration, and criminal law. Private law covers issues between private citizens or corporations. The most recent changes to the French legal system - introduced in the 1980s - were the decentralization laws, which transferred authority from centrally appointed government representatives to locally elected representatives of the people.
International Law - The law of the international community, or the body of customary rules and treaty rules accepted as legally binding by states in their relations with each other. International law differs from other legal systems in that it primarily concerns sovereign political entities. There are three separate disciplines of international law: public international law, which governs the relationship between provinces and international entities and includes treaty law, law of the sea, international criminal law, and international humanitarian law; private international law, which addresses legal jurisdiction; and supranational law - a legal framework wherein countries are bound by regional agreements in which the laws of the member countries are held inapplicable when in conflict with supranational laws. At present the European Union is the only entity under a supranational legal system. The term"international law" was coined by Jeremy Bentham in 1780 in his Principles of Morals and Legislation, though laws governing relations between states have been recognized from very early times (many centuries B.C.). Modern international law developed alongside the emergence and growth of the European nation-states beginning in the early 16th century. Other factors that influenced the development of international law included the revival of legal studies, the growth of international trade, and the practice of exchanging emissaries and establishing legations. The sources of International law are set out in Article 38-1 of the Statute of the International Court of Justice within the UN Charter.
Islamic Law - The most widespread type of religious law, it is the legal system enforced in over 30 countries, particularly in the Near East, but also in Central and South Asia, Africa, and Indonesia. In many countries Islamic law operates in tandem with a civil law system. Islamic law is embodied in the sharia, an Arabic word meaning"the right path." Sharia covers all aspects of public and private life and organizes them into five categories: obligatory, recommended, permitted, disliked, and forbidden. The primary sources of sharia law are the Qur'an, believed by Muslims to be the word of God revealed to the Prophet Muhammad by the angel Gabriel, and the Sunnah, the teachings of the Prophet and his works. In addition to these two primary sources, traditional Sunni Muslims recognize the consensus of Muhammad's companions and Islamic jurists on certain issues, called ijmas, and various forms of reasoning, including analogy by legal scholars, referred to as qiyas. Shia Muslims reject ijmas and qiyas as sources of sharia law.
Mixed Law - Also referred to as pluralistic law, mixed law consists of elements of some or all of the other main types of legal systems - civil, common, customary, and religious. The mixed legal systems of a number of countries came about when colonial powers overlaid their own legal systems upon colonized regions but retained elements of the colonies' existing legal systems.
Napoleonic Civil Code - A type of civil law, referred to as the Civil Code or Code Civil des Francais, forms part of the legal system of France, and underpins the legal systems of Bolivia, Egypt, Lebanon, Poland, and the US state of Louisiana. The Civil Code was established under Napoleon I, enacted in 1804, and officially designated the Code Napoleon in 1807. This legal system combined the Teutonic civil law tradition of the northern provinces of France with the Roman law tradition of the southern and eastern regions of the country. The Civil Code bears similarities in its arrangement to the Roman Body of Civil Law (see Civil Law above). As enacted in 1804, the Code addressed personal status, property, and the acquisition of property. Codes added over the following six years included civil procedures, commercial law, criminal law and procedures, and a penal code.
Religious Law - A legal system which stems from the sacred texts of religious traditions and in most cases professes to cover all aspects of life as a seamless part of devotional obligations to a transcendent, imminent, or deep philosophical reality. Implied as the basis of religious law is the concept of unalterability, because the word of God cannot be amended or legislated against by judges or governments. However, a detailed legal system generally requires human elaboration. The main types of religious law are sharia in Islam, halakha in Judaism, and canon law in some Christian groups. Sharia is the most widespread religious legal system (see Islamic Law), and is the sole system of law for countries including Iran, the Maldives, and Saudi Arabia. No country is fully governed by halakha, but Jewish people may decide to settle disputes through Jewish courts and be bound by their rulings. Canon law is not a divine law as such because it is not found in revelation. It is viewed instead as human law inspired by the word of God and applying the demands of that revelation to the actual situation of the church. Canon law regulates the internal ordering of the Roman Catholic Church, the Eastern Orthodox Church, and the Anglican Communion.
Roman Law - A type of civil law developed in ancient Rome and practiced from the time of the city's founding (traditionally 753 B.C.) until the fall of the Western Empire in the 5th century A.D. Roman law remained the legal system of the Byzantine (Eastern Empire) until the fall of Constantinople in 1453. Preserved fragments of the first legal text, known as the Law of the Twelve Tables, dating from the 5th century B.C., contained specific provisions designed to change the prevailing customary law. Early Roman law was drawn from custom and statutes; later, during the time of the empire, emperors asserted their authority as the ultimate source of law. The basis for Roman laws was the idea that the exact form - not the intention - of words or of actions produced legal consequences. It was only in the late 6th century A.D. that a comprehensive Roman code of laws was published (see Civil Law above). Roman law served as the basis of law systems developed in a number of continental European countries.
Roman-Dutch Law - A type of civil law based on Roman law as applied in the Netherlands. Roman-Dutch law serves as the basis for legal systems in seven African countries, as well as Guyana, Indonesia, and Sri Lanka. This law system, which originated in the province of Holland and expanded throughout the Netherlands (to be replaced by the French Civil Code in 1809), was instituted in a number of sub-Saharan African countries during the Dutch colonial period. The Dutch jurist/philosopher Hugo Grotius was the first to attempt to reduce Roman-Dutch civil law into a system in his Jurisprudence of Holland (written 1619-20, commentary published 1621). The Dutch historian/lawyer Simon van Leeuwen coined the term"Roman-Dutch law" in 1652.
Spanish Law - A type of civil law, often referred to as the Spanish Civil Code, it is the present legal system of Spain and is the basis of legal systems in 12 countries mostly in Central and South America, but also in southwestern Europe, northern and western Africa, and southeastern Asia. The Spanish Civil Code reflects a complex mixture of customary, Roman, Napoleonic, local, and modern codified law. The laws of the Visigoth invaders of Spain in the 5th to 7th centuries had the earliest major influence on Spanish legal system development. The Christian Reconquest of Spain in the 11th through 15th centuries witnessed the development of customary law, which combined canon (religious) and Roman law. During several centuries of Hapsburg and Bourbon rule, systematic recompilations of the existing national legal system were attempted, but these often conflicted with local and regional customary civil laws. Legal system development for most of the 19th century concentrated on formulating a national civil law system, which was finally enacted in 1889 as the Spanish Civil Code. Several sections of the code have been revised, the most recent of which are the penal code in 1989 and the judiciary code in 2001. The Spanish Civil Code separates public and private law. Public law includes constitutional law, administrative law, criminal law, process law, financial and tax law, and international public law. Private law includes civil law, commercial law, labor law, and international private law.
United States Law - A type of common law, which is the basis of the legal system of the United States and that of its island possessions in the Caribbean and the Pacific. This legal system has several layers, more possibly than in most other countries, and is due in part to the division between federal and state law. The United States was founded not as one nation but as a union of 13 colonies, each claiming independence from the British Crown. The US Constitution, implemented in 1789, began shifting power away from the states and toward the federal government, though the states today retain substantial legal authority. US law draws its authority from four sources: constitutional law, statutory law, administrative regulations, and case law. Constitutional law is based on the US Constitution and serves as the supreme federal law. Taken together with those of the state constitutions, these documents outline the general structure of the federal and state governments and provide the rules and limits of power. US statutory law is legislation enacted by the US Congress and is codified in the United States Code. The 50 state legislatures have similar authority to enact state statutes. Administrative law is the authority delegated to federal and state executive agencies. Case law, also referred to as common law, covers areas where constitutional or statutory law is lacking. Case law is a collection of judicial decisions, customs, and general principles that began in England centuries ago, that were adopted in America at the time of the Revolution, and that continue to develop today.
Of the approximately 240 countries with legislative bodies, approximately two-thirds are unicameral, and the remainder, bicameral. The selection of legislative members is typically governed by a country's constitution and/or its electoral laws. In general, members are either directly elected by a country's eligible voters using a defined electoral system; indirectly elected or selected by its province, state, or department legislatures; or appointed by the country's executive body. Legislative members in many countries are selected both directly and indirectly, and the electoral laws of some countries reserve seats for women and various ethnic and minority groups.
Worldwide, the two predominant direct voting systems are plurality/majority and proportional representation. The most common of the several plurality/majority systems is simple majority vote, or first-past-the-post, in which the candidate receiving the most votes is elected. Countries' legislatures such as Bangladesh's Parliament, Malaysia's House of Representatives, and the United Kingdom's House of Commons use this system. Another common plurality/majority system – absolute majority or two-round – requires that candidates win at least 50 percent of the votes to be elected. If none of the candidates meets that vote threshold in the initial election, a second poll or"runoff" is held soon after for the two top vote getters, and the candidate receiving a simple vote majority is declared the winner. Examples of the two-round system are Haiti's Chamber of Deputies, Mali's National Assembly, and Uzbekistan's Legislative Chamber. Other plurality/majority voting systems, referred to as preferential voting and generally used in multi-seat constituencies, are block vote and single non-transferable vote, in which voters cast their ballots by ranking their candidate preferences from highest to lowest.
Proportional representation electoral systems – in contrast to plurality/majority systems – generally award legislative seats to political parties in approximate proportion to the number of votes each receives. For example, in a 100-member legislature, if Party A receives 50 percent of the total vote, Party B, 30 percent, and Party C, 20 percent, then Party A would be awarded 50 seats, Party B 30 seats, and Party C 20 seats. There are various forms of proportional representation and the degree of reaching proportionality varies. Some forms of proportional representation are focused solely on achieving the proportional representation of different political parties and voters cast ballots only for political parties, whereas in other forms, voters cast ballots for individual candidates within a political party.
Many countries - both unicameral and bicameral - use a mix of electoral methods, in which a portion of legislative seats are awarded using one system, such as plurality/majority, while the remaining seats are awarded by another system, such as proportional representation. Many countries with bicameral legislatures use different voting systems for the two chambers.
The risk to an individual traveler varies considerably by the specific location, visit duration, type of activities, type of accommodations, time of year, and other factors. Consultation with a travel medicine physician is needed to evaluate individual risk and recommend appropriate preventive measures such as vaccines.
Diseases are organized into the following six exposure categories shown in italics and listed in typical descending order of risk. Note: The sequence of exposure categories listed in individual country entries may vary according to local conditions.
food or waterborne diseases acquired through eating or drinking on the local economy:
Hepatitis A - viral disease that interferes with the functioning of the liver; spread through consumption of food or water contaminated with fecal matter, principally in areas of poor sanitation; victims exhibit fever, jaundice, and diarrhea; 15% of victims will experience prolonged symptoms over 6-9 months; vaccine available.
Hepatitis E - water-borne viral disease that interferes with the functioning of the liver; most commonly spread through fecal contamination of drinking water; victims exhibit jaundice, fatigue, abdominal pain, and dark colored urine.
Typhoid fever - bacterial disease spread through contact with food or water contaminated by fecal matter or sewage; victims exhibit sustained high fevers; left untreated, mortality rates can reach 20%.
vectorborne diseases acquired through the bite of an infected arthropod:
Malaria - caused by single-cell parasitic protozoa Plasmodium; transmitted to humans via the bite of the female Anopheles mosquito; parasites multiply in the liver attacking red blood cells resulting in cycles of fever, chills, and sweats accompanied by anemia; death due to damage to vital organs and interruption of blood supply to the brain; endemic in 100, mostly tropical, countries with 90% of cases and the majority of 0.4-0.8 million estimated annual deaths occurring in sub-Saharan Africa.
Dengue fever - mosquito-borne (Aedes aegypti) viral disease associated with urban environments; manifests as sudden onset of fever and severe headache; occasionally produces shock and hemorrhage leading to death in 5% of cases.
Yellow fever - mosquito-borne (in urban areas Aedes aegypti) viral disease; severity ranges from influenza-like symptoms to severe hepatitis and hemorrhagic fever; occurs only in tropical South America and sub-Saharan Africa, where most cases are reported; fatality rate is less than 20%.
Japanese Encephalitis - mosquito-borne (Culex tritaeniorhynchus) viral disease associated with rural areas in Asia; acute encephalitis can progress to paralysis, coma, and death; fatality rates 30%.
African Trypanosomiasis - caused by the parasitic protozoa Trypanosoma; transmitted to humans via the bite of bloodsucking Tsetse flies; infection leads to malaise and irregular fevers and, in advanced cases when the parasites invade the central nervous system, coma and death; endemic in 36 countries of sub-Saharan Africa; cattle and wild animals act as reservoir hosts for the parasites.
Cutaneous Leishmaniasis - caused by the parasitic protozoa leishmania; transmitted to humans via the bite of sandflies; results in skin lesions that may become chronic; endemic in 88 countries; 90% of cases occur in Iran, Afghanistan, Syria, Saudi Arabia, Brazil, and Peru; wild and domesticated animals as well as humans can act as reservoirs of infection.
Plague - bacterial disease transmitted by fleas normally associated with rats; person-to-person airborne transmission also possible; recent plague epidemics occurred in areas of Asia, Africa, and South America associated with rural areas or small towns and villages; manifests as fever, headache, and painfully swollen lymph nodes; disease progresses rapidly and without antibiotic treatment leads to pneumonic form with a death rate in excess of 50%.
Crimean-Congo hemorrhagic fever - tick-borne viral disease; infection may also result from exposure to infected animal blood or tissue; geographic distribution includes Africa, Asia, the Middle East, and Eastern Europe; sudden onset of fever, headache, and muscle aches followed by hemorrhaging in the bowels, urine, nose, and gums; mortality rate is approximately 30%.
Rift Valley fever - viral disease affecting domesticated animals and humans; transmission is by mosquito and other biting insects; infection may also occur through handling of infected meat or contact with blood; geographic distribution includes eastern and southern Africa where cattle and sheep are raised; symptoms are generally mild with fever and some liver abnormalities, but the disease may progress to hemorrhagic fever, encephalitis, or ocular disease; fatality rates are low at about 1% of cases.
Chikungunya - mosquito-borne (Aedes aegypti) viral disease associated with urban environments, similar to Dengue Fever; characterized by sudden onset of fever, rash, and severe joint pain usually lasting 3-7 days, some cases result in persistent arthritis.
water contact diseases acquired through swimming or wading in freshwater lakes, streams, and rivers:
Leptospirosis - bacterial disease that affects animals and humans; infection occurs through contact with water, food, or soil contaminated by animal urine; symptoms include high fever, severe headache, vomiting, jaundice, and diarrhea; untreated, the disease can result in kidney damage, liver failure, meningitis, or respiratory distress; fatality rates are low but left untreated recovery can take months.
Schistosomiasis - caused by parasitic trematode flatworm Schistosoma; fresh water snails act as intermediate host and release larval form of parasite that penetrates the skin of people exposed to contaminated water; worms mature and reproduce in the blood vessels, liver, kidneys, and intestines releasing eggs, which become trapped in tissues triggering an immune response; may manifest as either urinary or intestinal disease resulting in decreased work or learning capacity; mortality, while generally low, may occur in advanced cases usually due to bladder cancer; endemic in 74 developing countries with 80% of infected people living in sub-Saharan Africa; humans act as the reservoir for this parasite.
aerosolized dust or soil contact disease acquired through inhalation of aerosols contaminated with rodent urine:
Lassa fever - viral disease carried by rats of the genus Mastomys; endemic in portions of West Africa; infection occurs through direct contact with or consumption of food contaminated by rodent urine or fecal matter containing virus particles; fatality rate can reach 50% in epidemic outbreaks.
respiratory disease acquired through close contact with an infectious person:
Meningococcal meningitis - bacterial disease causing an inflammation of the lining of the brain and spinal cord; one of the most important bacterial pathogens is Neisseria meningitidis because of its potential to cause epidemics; symptoms include stiff neck, high fever, headaches, and vomiting; bacteria are transmitted from person to person by respiratory droplets and facilitated by close and prolonged contact resulting from crowded living conditions, often with a seasonal distribution; death occurs in 5-15% of cases, typically within 24-48 hours of onset of symptoms; highest burden of meningococcal disease occurs in the hyperendemic region of sub-Saharan Africa known as the "Meningitis Belt" which stretches from Senegal east to Ethiopia.
animal contact disease acquired through direct contact with local animals:
Rabies - viral disease of mammals usually transmitted through the bite of an infected animal, most commonly dogs; virus affects the central nervous system causing brain alteration and death; symptoms initially are non-specific fever and headache progressing to neurological symptoms; death occurs within days of the onset of symptoms.
territorial sea - the sovereignty of a coastal state extends beyond its land territory and internal waters to an adjacent belt of sea, described as the territorial sea in the UNCLOS (Part II); this sovereignty extends to the air space over the territorial sea as well as its underlying seabed and subsoil; every state has the right to establish the breadth of its territorial sea up to a limit not exceeding 12 nautical miles; the normal baseline for measuring the breadth of the territorial sea is the mean low-water line along the coast as marked on large-scale charts officially recognized by the coastal state; where the coasts of two states are opposite or adjacent to each other, neither state is entitled to extend its territorial sea beyond the median line, every point of which is equidistant from the nearest points on the baseline from which the territorial seas of both states are measured; the UNCLOS describes specific rules for archipelagic states.
contiguous zone - according to the UNCLOS (Article 33), this is a zone contiguous to a coastal state's territorial sea, over which it may exercise the control necessary to: prevent infringement of its customs, fiscal, immigration, or sanitary laws and regulations within its territory or territorial sea; punish infringement of the above laws and regulations committed within its territory or territorial sea; the contiguous zone may not extend beyond 24 nautical miles from the baselines from which the breadth of the territorial sea is measured (e.g., the US has claimed a 12-nautical mile contiguous zone in addition to its 12-nautical mile territorial sea); where the coasts of two states are opposite or adjacent to each other, neither state is entitled to extend its contiguous zone beyond the median line, every point of which is equidistant from the nearest points on the baseline from which the contiguous zone of both states are measured.
exclusive economic zone (EEZ) - the UNCLOS (Part V) defines the EEZ as a zone beyond and adjacent to the territorial sea in which a coastal state has: sovereign rights for the purpose of exploring and exploiting, conserving and managing the natural resources, whether living or non-living, of the waters superjacent to the seabed and of the seabed and its subsoil, and with regard to other activities for the economic exploitation and exploration of the zone, such as the production of energy from the water, currents, and winds; jurisdiction with regard to the establishment and use of artificial islands, installations, and structures; marine scientific research; the protection and preservation of the marine environment; the outer limit of the exclusive economic zone shall not exceed 200 nautical miles from the baselines from which the breadth of the territorial sea is measured.
continental shelf - the UNCLOS (Article 76) defines the continental shelf of a coastal state as comprising the seabed and subsoil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured where the outer edge of the continental margin does not extend up to that distance; the continental margin comprises the submerged prolongation of the landmass of the coastal state, and consists of the seabed and subsoil of the shelf, the slope and the rise; wherever the continental margin extends beyond 200 nautical miles from the baseline, coastal states may extend their claim to a distance not to exceed 350 nautical miles from the baseline or 100 nautical miles from the 2,500-meter isobath, which is a line connecting points of 2,500 meters in depth; it does not include the deep ocean floor with its oceanic ridges or the subsoil thereof.
exclusive fishing zone - while this term is not used in the UNCLOS, some states (e.g., the United Kingdom) have chosen not to claim an EEZ but rather to claim jurisdiction over the living resources off their coast; in such cases, the term exclusive fishing zone is often used; the breadth of this zone is normally the same as the EEZ or 200 nautical miles.
This entry provides estimates of military and security services personnel strengths. The numbers are based on a wide-range of publicly available information. Unless otherwise noted, military estimates focus on the major services (army, navy, air force, and where applicable, gendarmeries) and do not account for activated reservists or delineate military service members assigned to joint staffs or defense ministries.

Some distinctive types of population pyramids are:
- A youthful distribution has a broad base and narrow peak and is characterized by a high proportion of children and low proportion of the elderly. This population distribution results from high fertility, high mortality, low life expectancy, and high population growth. It is typical of developing countries where female education and contraceptive use are low and health care and sanitation are poor.
- A transitional distribution is caused by declining fertility and mortality rates, increasing life expectancy, and slowing population growth. The population has a larger proportion of working-age people relative to children and the elderly and produces a barrel-shaped pyramid, where the mid-section bulges and the base and top are narrower. The large proportion of working-age people can create a “demographic bonus” if it is educated and productively employed.
- A mature distribution has fairly balanced proportions of the population in the child, working-age, and elderly age groups and will gradually form an inverted triangle population pyramid as population growth continues to fall or ceases and the proportion of older people increases. Low fertility, low mortality, and high life expectancy - made possible by the availability of advanced healthcare, family planning, sanitation, and education - lead to aging populations in industrialized countries.
Baha'i - Founded by Mirza Husayn-Ali (known as Baha'u'llah) in Iran in 1852, Baha'i faith emphasizes monotheism and believes in one eternal transcendent God. Its guiding focus is to encourage the unity of all peoples on the earth so that justice and peace may be achieved on earth. Baha'i revelation contends the prophets of major world religions reflect some truth or element of the divine, believes all were manifestations of God given to specific communities in specific times, and that Baha'u'llah is an additional prophet meant to call all humankind. Bahais are an open community, located worldwide, with the greatest concentration of believers in South Asia.
Buddhism - Religion or philosophy inspired by the 5th century B.C. teachings of Siddhartha Gautama (also known as Gautama Buddha "the enlightened one"). Buddhism focuses on the goal of spiritual enlightenment centered on an understanding of Gautama Buddha's Four Noble Truths on the nature of suffering, and on the Eightfold Path of spiritual and moral practice, to break the cycle of suffering of which we are a part. Buddhism ascribes to a karmic system of rebirth. Several schools and sects of Buddhism exist, differing often on the nature of the Buddha, the extent to which enlightenment can be achieved - for one or for all, and by whom - religious orders or laity.
Basic Groupings
Theravada Buddhism: The oldest Buddhist school, Theravada is practiced mostly in Sri Lanka, Cambodia, Laos, Burma, and Thailand, with minority representation elsewhere in Asia and the West. Theravadans follow the Pali Canon of Buddha's teachings, and believe that one may escape the cycle of rebirth, worldly attachment, and suffering for oneself; this process may take one or several lifetimes.
Mahayana Buddhism, including subsets Zen and Tibetan (Lamaistic) Buddhism: Forms of Mahayana Buddhism are common in East Asia and Tibet, and parts of the West. Mahayanas have additional scriptures beyond the Pali Canon and believe the Buddha is eternal and still teaching. Unlike Theravada Buddhism, Mahayana schools maintain the Buddha-nature is present in all beings and all will ultimately achieve enlightenment.
Hoa Hao: a minority tradition of Buddhism practiced in Vietnam that stresses lay participation, primarily by peasant farmers; it eschews expensive ceremonies and temples and relocates the primary practices into the home.
Christianity - Descending from Judaism, Christianity's central belief maintains Jesus of Nazareth is the promised messiah of the Hebrew Scriptures, and that his life, death, and resurrection are salvific for the world. Christianity is one of the three monotheistic Abrahamic faiths, along with Islam and Judaism, which traces its spiritual lineage to Abraham of the Hebrew Scriptures. Its sacred texts include the Hebrew Bible and the New Testament (or the Christian Gospels).
Basic Groupings
Catholicism (or Roman Catholicism): This is the oldest established western Christian church and the world's largest single religious body. It is supranational, and recognizes a hierarchical structure with the Pope, or Bishop of Rome, as its head, located at the Vatican. Catholics believe the Pope is the divinely ordered head of the Church from a direct spiritual legacy of Jesus' apostle Peter. Catholicism is comprised of 23 particular Churches, or Rites - one Western (Roman or Latin-Rite) and 22 Eastern. The Latin Rite is by far the largest, making up about 98% of Catholic membership. Eastern-Rite Churches, such as the Maronite Church and the Ukrainian Catholic Church, are in communion with Rome although they preserve their own worship traditions and their immediate hierarchy consists of clergy within their own rite. The Catholic Church has a comprehensive theological and moral doctrine specified for believers in its catechism, which makes it unique among most forms of Christianity.
Mormonism (including the Church of Jesus Christ of Latter-Day Saints): Originating in 1830 in the United States under Joseph Smith, Mormonism is not characterized as a form of Protestant Christianity because it claims additional revealed Christian scriptures after the Hebrew Bible and New Testament. The Book of Mormon maintains there was an appearance of Jesus in the New World following the Christian account of his resurrection, and that the Americas are uniquely blessed continents. Mormonism believes earlier Christian traditions, such as the Roman Catholic, Orthodox, and Protestant reform faiths, are apostasies and that Joseph Smith's revelation of the Book of Mormon is a restoration of true Christianity. Mormons have a hierarchical religious leadership structure, and actively proselytize their faith; they are located primarily in the Americas and in a number of other Western countries.
Jehovah's Witnesses structure their faith on the Christian Bible, but their rejection of the Trinity is distinct from mainstream Christianity. They believe that a Kingdom of God, the Theocracy, will emerge following Armageddon and usher in a new earthly society. Adherents are required to evangelize and to follow a strict moral code.
Orthodox Christianity: The oldest established eastern form of Christianity, the Holy Orthodox Church, has a ceremonial head in the Bishop of Constantinople (Istanbul), also known as a Patriarch, but its various regional forms (e.g., Greek Orthodox, Russian Orthodox, Serbian Orthodox, Ukrainian Orthodox) are autocephalous (independent of Constantinople's authority, and have their own Patriarchs). Orthodox churches are highly nationalist and ethnic. The Orthodox Christian faith shares many theological tenets with the Roman Catholic Church, but diverges on some key premises and does not recognize the governing authority of the Pope.
Protestant Christianity: Protestant Christianity originated in the 16th century as an attempt to reform Roman Catholicism's practices, dogma, and theology. It encompasses several forms or denominations which are extremely varied in structure, beliefs, relationship to state, clergy, and governance. Many protestant theologies emphasize the primary role of scripture in their faith, advocating individual interpretation of Christian texts without the mediation of a final religious authority such as the Roman Pope. The oldest Protestant Christianities include Lutheranism, Calvinism (Presbyterians), and Anglican Christianity (Episcopalians), which have established liturgies, governing structure, and formal clergy. Other variants on Protestant Christianity, including Pentecostal movements and independent churches, may lack one or more of these elements, and their leadership and beliefs are individualized and dynamic.
Hinduism - Originating in the Vedic civilization of India (second and first millennium B.C.), Hinduism is an extremely diverse set of beliefs and practices with no single founder or religious authority. Hinduism has many scriptures; the Vedas, the Upanishads, and the Bhagavad-Gita are among some of the most important. Hindus may worship one or many deities, usually with prayer rituals within their own home. The most common figures of devotion are the gods Vishnu, Shiva, and a mother goddess, Devi. Most Hindus believe the soul, or atman, is eternal, and goes through a cycle of birth, death, and rebirth (samsara) determined by one's positive or negative karma, or the consequences of one's actions. The goal of religious life is to learn to act so as to finally achieve liberation (moksha) of one's soul, escaping the rebirth cycle.
Islam - The third of the monotheistic Abrahamic faiths, Islam originated with the teachings of Muhammad in the 7th century. Muslims believe Muhammad is the final of all religious prophets (beginning with Abraham) and that the Qu'ran, which is the Islamic scripture, was revealed to him by God. Islam derives from the word submission, and obedience to God is a primary theme in this religion. In order to live an Islamic life, believers must follow the five pillars, or tenets, of Islam, which are the testimony of faith (shahada), daily prayer (salah), giving alms (zakah), fasting during Ramadan (sawm), and the pilgrimage to Mecca (hajj).
Basic Groupings
The two primary branches of Islam are Sunni and Shia, which split from each other over a religio-political leadership dispute about the rightful successor to Muhammad. The Shia believe Muhammad's cousin and son-in-law, Ali, was the only divinely ordained Imam (religious leader), while the Sunni maintain the first three caliphs after Muhammad were also legitimate authorities. In modern Islam, Sunnis and Shia continue to have different views of acceptable schools of Islamic jurisprudence, and who is a proper Islamic religious authority. Islam also has an active mystical branch, Sufism, with various Sunni and Shia subsets.
Sunni Islam accounts for over 75% of the world's Muslim population. It recognizes the Abu Bakr as the first caliph after Muhammad. Sunni has four schools of Islamic doctrine and law - Hanafi, Maliki, Shafi'i, and Hanbali - which uniquely interpret the Hadith, or recorded oral traditions of Muhammad. A Sunni Muslim may elect to follow any one of these schools, as all are considered equally valid.
Shia Islam represents 10-20% of Muslims worldwide, and its distinguishing feature is its reverence for Ali as an infallible, divinely inspired leader, and as the first Imam of the Muslim community after Muhammad. A majority of Shia are known as "Twelvers," because they believe that the 11 familial successor imams after Muhammad culminate in a 12th Imam (al-Mahdi) who is hidden in the world and will reappear at its end to redeem the righteous.
Variants
Ismaili faith: A sect of Shia Islam, its adherents are also known as "Seveners," because they believe that the rightful seventh Imam in Islamic leadership was Isma'il, the elder son of Imam Jafar al-Sadiq. Ismaili tradition awaits the return of the seventh Imam as the Mahdi, or Islamic messianic figure. Ismailis are located in various parts of the world, particularly South Asia and the Levant.
Alawi faith: Another Shia sect of Islam, the name reflects followers' devotion to the religious authority of Ali. Alawites are a closed, secretive religious group who assert they are Shia Muslims, although outside scholars speculate their beliefs may have a syncretic mix with other faiths originating in the Middle East. Alawis live mostly in Syria, Lebanon, and Turkey.
Druze faith: A highly secretive tradition and a closed community that derives from the Ismaili sect of Islam; its core beliefs are thought to emphasize a combination of Gnostic principles believing that the Fatimid caliph, al-Hakin, is the one who embodies the key aspects of goodness of the universe, which are, the intellect, the word, the soul, the preceder, and the follower. The Druze have a key presence in Syria, Lebanon, and Israel.
Jainism - Originating in India, Jain spiritual philosophy believes in an eternal human soul, the eternal universe, and a principle of "the own nature of things." It emphasizes compassion for all living things, seeks liberation of the human soul from reincarnation through enlightenment, and values personal responsibility due to the belief in the immediate consequences of one's behavior. Jain philosophy teaches non-violence and prescribes vegetarianism for monks and laity alike; its adherents are a highly influential religious minority in Indian society.
Judaism - One of the first known monotheistic religions, likely dating to between 2000-1500 B.C., Judaism is the native faith of the Jewish people, based upon the belief in a covenant of responsibility between a sole omnipotent creator God and Abraham, the patriarch of Judaism's Hebrew Bible, or Tanakh. Divine revelation of principles and prohibitions in the Hebrew Scriptures form the basis of Jewish law, or halakhah, which is a key component of the faith. While there are extensive traditions of Jewish halakhic and theological discourse, there is no final dogmatic authority in the tradition. Local communities have their own religious leadership. Modern Judaism has three basic categories of faith: Orthodox, Conservative, and Reform/Liberal. These differ in their views and observance of Jewish law, with the Orthodox representing the most traditional practice, and Reform/Liberal communities the most accommodating of individualized interpretations of Jewish identity and faith.
Shintoism - A native animist tradition of Japan, Shinto practice is based upon the premise that every being and object has its own spirit or kami. Shinto practitioners worship several particular kamis, including the kamis of nature, and families often have shrines to their ancestors' kamis. Shintoism has no fixed tradition of prayers or prescribed dogma, but is characterized by individual ritual. Respect for the kamis in nature is a key Shinto value. Prior to the end of World War II, Shinto was the state religion of Japan, and bolstered the cult of the Japanese emperor.
Sikhism - Founded by the Guru Nanak (born 1469), Sikhism believes in a non-anthropomorphic, supreme, eternal, creator God; centering one's devotion to God is seen as a means of escaping the cycle of rebirth. Sikhs follow the teachings of Nanak and nine subsequent gurus. Their scripture, the Guru Granth Sahib - also known as the Adi Granth - is considered the living Guru, or final authority of Sikh faith and theology. Sikhism emphasizes equality of humankind and disavows caste, class, or gender discrimination.
Taoism - Chinese philosophy or religion based upon Lao Tzu's Tao Te Ching, which centers on belief in the Tao, or the way, as the flow of the universe and the nature of things. Taoism encourages a principle of non-force, or wu-wei, as the means to live harmoniously with the Tao. Taoists believe the esoteric world is made up of a perfect harmonious balance and nature, while in the manifest world - particularly in the body - balance is distorted. The Three Jewels of the Tao - compassion, simplicity, and humility - serve as the basis for Taoist ethics.
Zoroastrianism - Originating from the teachings of Zoroaster in about the 9th or 10th century B.C., Zoroastrianism may be the oldest continuing creedal religion. Its key beliefs center on a transcendent creator God, Ahura Mazda, and the concept of free will. The key ethical tenets of Zoroastrianism expressed in its scripture, the Avesta, are based on a dualistic worldview where one may prevent chaos if one chooses to serve God and exercises good thoughts, good words, and good deeds. Zoroastrianism is generally a closed religion and members are almost always born to Zoroastrian parents. Prior to the spread of Islam, Zoroastrianism dominated greater Iran. Today, though a minority, Zoroastrians remain primarily in Iran, India (where they are known as Parsi), and Pakistan.
Traditional beliefs
Animism: the belief that non-human entities contain souls or spirits.
Badimo: a form of ancestor worship of the Tswana people of Botswana.
Confucianism: an ideology that humans are perfectible through self-cultivation and self-creation; developed from teachings of the Chinese philosopher Confucius. Confucianism has strongly influenced the culture and beliefs of East Asian countries, including China, Japan, Korea, Singapore, Taiwan, and Vietnam.
Inuit beliefs are a form of shamanism (see below) based on animistic principles of the Inuit or Eskimo peoples.

Pagan is a blanket term used to describe many unconnected belief practices throughout history, usually in reference to religions outside of the Abrahamic category (monotheistic faiths like Judaism, Christianity, and Islam).
Shamanism: beliefs and practices promoting communication with the spiritual world. Shamanistic beliefs are organized around a shaman or medicine man who - as an intermediary between the human and spirit world - is believed to be able to heal the sick (by healing their souls), communicate with the spirit world, and help souls into the afterlife through the practice of entering a trance. In shaman-based religions, the shaman is also responsible for leading sacred rites.
Spiritualism: the belief that souls and spirits communicate with the living usually through intermediaries called mediums.
Syncretic (fusion of diverse religious beliefs and practices)
Cao Dai: a nationalistic Vietnamese sect, officially established in 1926, that draws practices and precepts from Confucianism, Taoism, Buddhism, and Catholicism.
Chondogyo: or the religion of the Heavenly Way, is based on Korean shamanism, Buddhism, and Korean folk traditions, with some elements drawn from Christianity. Formulated in the 1860s, it holds that God lives in all of us and strives to convert society into a paradise on earth, populated by believers transformed into intelligent moral beings with a high social conscience.
Kimbanguist: a puritan form of the Baptist denomination founded by Simon Kimbangu in the 1920s in what is now the Democratic Republic of Congo. Adherents believe that salvation comes through Jesus' death and resurrection, like Christianity, but additionally that living a spiritually pure life following strict codes of conduct is required for salvation.
Modekngei: a hybrid of Christianity and ancient Palauan culture and oral traditions founded around 1915 on the island of Babeldaob. Adherents simultaneously worship Jesus Christ and Palauan goddesses.
Rastafarian: an afro-centrist ideology and movement based on Christianity that arose in Jamaica in the 1930s; it believes that Haile Selassie I, Emperor of Ethiopia from 1930-74, was the incarnation of the second coming of Jesus.
Santeria: practiced in Cuba, the merging of the Yoruba religion of Nigeria with Roman Catholicism and native Indian traditions. Its practitioners believe that each person has a destiny and eventually transcends to merge with the divine creator and source of all energy, Olorun.
Voodoo/Vodun: a form of spirit and ancestor worship combined with some Christian faiths, especially Catholicism. Haitian and Louisiana Voodoo, which have included more Catholic practices, are separate from West African Vodun, which has retained a focus on spirit worship.
Non-religious
Agnosticism: the belief that most things are unknowable. In regard to religion it is usually characterized as neither a belief nor non belief in a deity.
Atheism: the belief that there are no deities of any kind.
2G - is short for second-generation cellular network. After 2G was launched, the previous mobile wireless network systems were retroactively dubbed 1G. While radio signals on 1G networks are analog, radio signals on 2G networks are digital. Both systems use digital signaling to connect the radio towers (which listen to the devices) to the rest of the mobile system.
3G - is the third generation of wireless mobile telecommunications technology. It is the upgrade for 2.5G and 2.5G GPRS networks, for faster data transfer. This increased speed is based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls, and mobile TV.
4G - is the fourth generation of broadband cellular network technology, succeeding 3G. The first-release Long Term Evolution (LTE) standard was commercially deployed in Oslo, Norway, and Stockholm, Sweden in 2009, and has since been deployed throughout most parts of the world. Applications, include enhanced mobile web access, IP telephony, high-definition mobile TV, and video conferencing.
5G - is the fifth generation technology standard for cellular networks, which cellular phone companies began deploying worldwide in 2019; it is the planned successor to the 4G networks which provide connectivity to most current cellphones. Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. The main advantage of the new networks is that they will have greater bandwidth, allowing higher download speeds, eventually up to 10 gigabits per second (Gbit/s). Due to the increased bandwidth, the expectation is that the new networks will not just serve cellphones like existing cellular networks, but also be used as general Internet service providers for laptops and desktop computers, competing with existing ISPs such as cable Internet. Existing 4G cellphones will not be able to use the new networks, which will require new 5G-enabled wireless devices.
ADSL - Asymmetric Digital Subscriber Line (ADSL) is a type of digital subscriber line (DSL) that allows faster data transmission via copper service phone lines to a home or business. ADSL provides an “always on” connection and higher speeds than dial-up Internet can provide. In ADSL, bandwidth and bit rate (i.e., speed) are asymmetric, meaning greater toward the customer (downstream) than the reverse (upstream).

As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber. FTTX is a general term for several configurations of fiber deployment, broadly organized into two groups: FTTN and FTTP /H/B. Fiber to the node (FTTN), also referred to as Fiber to the neighborhood, delivers fiber to within 300m (1,000 ft) of a customer’s premises. Fiber to the premises (FTTP) can be further categorized as fiber to the home (FTTH) or fiber to the building/business (FTTB). FTTN (and FTTC, fiber to the curb (to less than 300m (1,000 ft of a customer’s premises)) are seen as interim steps toward full FTTP.
GPON - stands for Gigabyte Passive Optical Networks, which are networks that rely on optical cables to deliver information from a single feeding fiber from a provider - to multiple destinations - via the use of splitters. GPONs are currently the leading form of Passive Optical Networks (PON) and offer up to a 1:64 ratio on a single fiber. As opposed to a standard copper wire in most networks, GPONs are 95% more energy efficient.

LTE-TDD & LTE-FDD - There are two major differences between LTE-TDD and LTE-FDD: how data is uploaded and downloaded, and what frequency spectra the networks are deployed in. While LTE-FDD uses paired frequencies to upload and download data, LTE-TDD uses a single frequency, alternating between uploading and downloading data through time. The ratio between uploads and downloads on a LTE-TDD network can be changed dynamically, depending on whether more data needs to be sent or received. LTE-TDD and LTE-FDD also operate on different frequency bands, with LTE-TDD working better at higher frequencies, and LTE-FDD working better at lower frequencies.

Solidaridad - geosynchronous satellites in Mexico's system of international telecommunications in the Western Hemisphere.
Spectrum - spectrum management is the allocation and regulation of the electromagnetic spectrum into radio frequency (RF) bands, a procedure normally carried out by governments in most countries. Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation of RF bands and their standardization. A spectrum auction is a process whereby a government uses an auction system to sell the rights to transmit signals over specific bands of the electromagnetic spectrum and to assign scarce spectrum resources.
Submarine cable - a cable designed for service under water.
Telecommunication (telecom) - is the exchange of signs, signals, messages, words, images and sounds, or information of any nature by wire, radio, optical, or other electromagnetic systems (i.e., via the use of technology).
