Definitions

Age distribution > Median age: The median age of the country's residents. This is the age most people are in the country.
Age distribution > Population aged 0-14: Percentage of total population aged 0-14.
Age distribution > Population aged 0-14 > Total: Number of people aged 0-14.
Age distribution > Population aged 15-24 > Percent: Percentage of total population aged 15-24.
Age distribution > Population aged 15-24 > Total: Number of people aged 15-24.
Age distribution > Population aged 60 or over > Percent: Percentage of total population aged 60 and older.
Age distribution > Total dependency ratio: Percentage of dependant persons out of total population aged 15-64. A dependant person is a person aged 0-14 and those over 65 years old.
Birth rate: The average annual number of births during a year per 1,000 persons in the population at midyear; also known as crude birth rate. The birth rate is usually the dominant factor in determining the rate of population growth. It depends on both the level of fertility and the age structure of the population.
Death rate: The average annual number of deaths during a year per 1,000 population at midyear; also known as crude death rate. The death rate, while only a rough indicator of the mortality situation in a country, accurately indicates the current mortality impact on population growth. This indicator is significantly affected by age distribution, and most countries will eventually show a rise in the overall death rate, in spite of continued decline in mortality at all ages, as declining fertility results in an aging population.
Ethnic groups: This entry provides a rank ordering of ethnic groups starting with the largest and normally includes the percent of total population.
Gender > Female population: Total female population.
Population: Population, total refers to the total population.
Population > Population growth, past and future: Population growth rate (percentage).
Population growth: Percentage by which country's population either has increased or is estimated to increase. Countries with a decrease in population are signified by a negative percentage. Future estimates are from the UN Population Division.
Population growth rate: The average annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative. The growth rate is a factor in determining how great a burden would be imposed on a country by the changing needs of its people for infrastructure (e.g., schools, hospitals, housing, roads), resources (e.g., food, water, electricity), and jobs. Rapid population growth can be seen as threatening by neighboring countries.
Age distribution > Population aged 15-64 > Total: Number of people aged 15-64.
Age distribution > Population aged 0-4 > Total: Number of people aged 0-4.
Obesity > Adult obesity rate: This entry gives the percent of a country's population considered to be obese. Obesity is defined as an adult having a Body Mass Index (BMI) greater to or equal to 30.0. BMI is calculated by taking a person's weight in kg and dividing it by the person's squared height in meters.
Age distribution > Population aged 15-59: Percentage of total pouplation aged 15-59.
Population in 2015: (Thousands) Medium-variant projections.
Urban and rural > Population living in cities proper: Each city population by sex, city and city type.
Death rate, crude > Per 1,000 people: Death rate, crude (per 1,000 people). Crude death rate indicates the number of deaths occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
Total fertility rate: The average number of children that would be born per woman if all women lived to the end of their child-bearing years and bore children according to a given fertility rate at each age. The total fertility rate is a more direct measure of the level of fertility than the crude birth rate, since it refers to births per woman. This indicator shows the potential for population growth in the country. High rates will also place some limits on the labor force participation rates for women. Large numbers of children born to women indicate large family sizes that might limit the ability of the families to feed and educate their children.
Age distribution > Population aged 65 or over > Percent: Percentage of total population aged 65 and older.
Age dependency ratio > Dependents to working-age population: Age dependency ratio is the ratio of dependents--people younger than 15 or older than 64--to the working-age population--those ages 15-64. For example, 0.7 means there are 7 dependents for every 10 working-age people.
Age structure > 0-14 years: The distribution of the population according to age. Information is included by sex and age group (0-14 years, 15-64 years, 65 years and over). The age structure of a population affects a nation's key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.
Gender > Male population: Total male population.
Age distribution > Population aged 60 or over > Total: Number of people aged 60 and older.
Age distribution > Population aged 15-64: Percentage of total population aged 15-64.
Age structure > 65 years and over: The distribution of the population according to age. Information is included by sex and age group (0-14 years, 15-64 years, 65 years and over). The age structure of a population affects a nation's key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest."
Nationality > Noun: The noun which identifies citizens of the nation
Age distribution > Elderly dependency ratio: Percentage of dependant adults out of total population aged 15-64. A dependant adult is an adult aged 65 and older.
Age distribution > Population aged 0-4 > Percent: Percentage of total population aged 0-4.
Physicians density: This entry gives the number of medical doctors (physicians), including generalist and specialist medical practitioners, per 1,000 of the population. Medical doctors are defined as doctors that study, diagnose, treat, and prevent illness, disease, injury, and other physical and mental impairments in humans through the application of modern medicine. They also plan, supervise, and evaluate care and treatment plans by other health care providers. The World Health Organization estimates that fewer than 2.3 health workers (physicians, nurses, and midwives only) per 1,000 would be insufficient to achieve coverage of primary healthcare needs.
Age distribution > Population aged 65 or over > Total: Number of people 65 years old and older.
Age distribution > Population aged 15-59 > Total: Number of people aged 15-59.
Age distribution > Population aged 80 or over > Total: Number of people aged 80 years and older.
Cities > Urban population: Total population living in urban areas. The defition of an urban area differs for each country. Future estimates are from the UN Population Division.
Nationality > Adjective: This entry is derived from People > Nationality, which provides the identifying terms for citizens - noun and adjective.
Sex ratio > Total population: The number of males for each female one of five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually it could cause unrest among young adult males who are unable to find partners.
Age distribution > Population aged 5-14 > Percent: Percentage of total population aged 5-14.
Sex ratio > At birth: The number of males for each female one of five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually it could cause unrest among young adult males who are unable to find partners.
Age distribution > Population aged 80 or over > Percent: Percentage of total population aged 80 and older.
Gender > Sex ratio at birth: Number of males born for every female born. Countries with a number less than one have more females born than males.
Age distribution > Population aged 5-14 > Total: Number of people aged 5-14.
Migration > Net migration rate: The difference between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration (e.g., 3.56 migrants/1,000 population); an excess of persons leaving the country as net emigration (e.g., -9.26 migrants/1,000 population). The net migration rate indicates the contribution of migration to the overall level of population change. High levels of migration can cause problems such as increasing unemployment and potential ethnic strife (if people are coming in) or a reduction in the labor force, perhaps in certain key sectors (if people are leaving).
Future population change: Total change in population by country. Future estimates are from the UN Population Division.
Urban population: Urban population is the midyear population of areas defined as urban in each country and reported to the United Nations.
Median age > Total: This entry is derived from People > Median age, which is the age that divides a population into two numerically equal groups; that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population. Currently, the median age ranges from a low of about 15 in Uganda and Gaza Strip to 40 or more in several European countries and Japan. See the entry for "Age structure" for the importance of a young versus an older age structure and, by implication, a low versus a higher median age.
Life expectancy at birth > Total population: This entry is derived from People > Life expectancy at birth, which contains the average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future. The entry includes total population as well as the male and female components. Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages. It can also be thought of as indicating the potential return on investment in human capital and is necessary for the calculation of various actuarial measures.
Urban and rural > Urban population: Total population living in urban areas by country.
Projected population growth: Percentage change in projected population between 2000 and 2050
Units: Percent Change in Population
Units: A threshold of 0 was applied. All countries with growth rates of 0 or below received the same score.
Marriage > Years being single before marriage > Women: Average age of women at their first marriage.
Age structure > 15-64 years: The distribution of the population according to age. Information is included by sex and age group (0-14 years, 15-64 years, 65 years and over). The age structure of a population affects a nation's key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.
Literacy > Total population: This entry is derived from People > Literacy, which includes a definition of literacy and Census Bureau percentages for the total population, males, and females. There are no universal definitions and standards of literacy. Unless otherwise specified, all rates are based on the most common definition - the ability to read and write at a specified age. Detailing the standards that individual countries use to assess the ability to read and write is beyond the scope of the Factbook. Information on literacy, while not a perfect measure of educational results, is probably the most easily available and valid for international comparisons. Low levels of literacy, and education in general, can impede the economic development of a country in the current rapidly changing, technology-driven world.

Dependency ratios > Youth dependency ratio: This entry is derived from People > Dependency ratios, which dependency ratios are a measure of the age structure of a population. They relate the number of individuals that are likely to be economically "dependent" on the support of others. Dependency ratios contrast the ratio of youths (ages 0-14) and the elderly (ages 65+) to the number of those in the working-age group (ages 15-64). Changes in the dependency ratio provide an indication of potential social support requirements resulting from changes in population age structures. As fertility levels decline, the dependency ratio initially falls because the proportion of youths decreases while the proportion of the population of working age increases. As fertility levels continue to decline, dependency ratios eventually increase because the proportion of the population of working age starts to decline and the proportion of elderly persons continues to increase.
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.
Marriage > Years being single before marriage > Men: Average age of men at their first marriage.
Age distribution > Child dependency ratio: Percentage of dependant children out of total population aged 15 and older. A dependant child is a child aged 0-14.
Gender > Women aged 15-49: Country's total population of women aged 15-49. Future estimates are from the UN Population Division.
Percentage living in urban areas: Percentage of people living in urban areas. Data for 2003. Urban-rural classification of population in internationally published statistics follows the national census definition, which differs from one country or area to another. National definitions are usually based on criteria that may include any of the following: size of population in a locality, population density, distance between built-up areas, predominant type of economic activity, legal or administrative boundaries and urban characteristics such as specific services and facilities.
Population > CIA Factbook: This entry gives an estimate from the US Bureau of the Census based on statistics from population censuses, vital statistics registration systems, or sample surveys pertaining to the recent past and on assumptions about future trends. The total population presents one overall measure of the potential impact of the country on the world and within its region. Note: starting with the 1993 Factbook, demographic estimates for some countries (mostly African) have explicitly taken into account the effects of the growing impact of the HIV/AIDS epidemic. These countries are currently: The Bahamas, Benin, Botswana, Brazil, Burkina Faso, Burma, Burundi, Cambodia, Cameroon, Central African Republic, Democratic Republic of the Congo, Republic of the Congo, Cote d'Ivoire, Ethiopia, Gabon, Ghana, Guyana, Haiti, Honduras, Kenya, Lesotho, Malawi, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Swaziland, Tanzania, Thailand, Togo, Uganda, Zambia, and Zimbabwe.
Sex ratio > Under 15 years: The number of males for each female one of five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually it could cause unrest among young adult males who are unable to find partners.
Percentage living in rural areas.: Percentage of people living in rural areas. Data for 2003. Urban-rural classification of population in internationally published statistics follows the national census definition, which differs from one country or area to another. National definitions are usually based on criteria that may include any of the following: size of population in a locality, population density, distance between built-up areas, predominant type of economic activity, legal or administrative boundaries and urban characteristics such as specific services and facilities.
Infant mortality rate > Total: This entry is derived from People > Infant mortality rate, which gives the number of deaths of infants under one year old in a given year per 1,000 live births in the same year; included is the total death rate, and deaths by sex, male and female. This rate is often used as an indicator of the level of health in a country.
Age structure > 25-54 years: This entry is derived from People > Age structure, which provides the distribution of the population according to age. Information is included by sex and age group as follows: 0-14 years (children), 15-24 years (early working age), 25-54 years (prime working age), 55-64 years (mature working age), 65 years and over (elderly). The age structure of a population affects a nation's key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.
Urban and rural > Rural population: Total population living in rural areas by country.
Gender > Global Gender Gap Index: The Gender Gap Index considers gender inequality in the dimensions of economic participation (equality of salaries, labor market participation and access to high-skilled employment); access to education; political participation; and health (life expectancy and sex ratio). The highest score of 1 means total equality, 0 means complete inequality. The Index is calculated by the World Economic Forum.
Age structure > 15-24 years: This entry is derived from People > Age structure, which provides the distribution of the population according to age. Information is included by sex and age group as follows: 0-14 years (children), 15-24 years (early working age), 25-54 years (prime working age), 55-64 years (mature working age), 65 years and over (elderly). The age structure of a population affects a nation's key socioeconomic issues.

Urban and rural > Urban population per thousand people: Total population living in urban areas by country. Figures expressed per thousand people for the same year.
Rural population: Rural population is calculated as the difference between the total population and the urban population.
Fertility > Fertility rate, total > Births per woman: Fertility rate, total (births per woman). Total fertility rate represents the number of children that would be born to a woman if she were to live to the end of her childbearing years and bear children in accordance with current age-specific fertility rates.
Age structure > 55-64 years: This entry is derived from People > Age structure, which provides the distribution of the population according to age.

Future population > Males: UN estimates of male population in 2010, 2015, 2020, 2025 and 2030.
School life expectancy > Primary to tertiary > Total: This entry is derived from People > School life expectancy > Primary to tertiary , which school life expectancy (SLE) is the total number of years of schooling (primary to tertiary) that a child can expect to receive, assuming that the probability of his or her being enrolled in school at any particular future age is equal to the current enrollment ratio at that age.Caution must be maintained when utilizing this indicator in international comparisons. For example, a year or grade completed in one country is not necessarily the same in terms of educational content or quality as a year or grade completed in another country. SLE represents the expected number of years of schooling that will be completed, including years spent repeating one or more grades.
Fertility > Birth rate, crude > Per 1,000 people: Birth rate, crude (per 1,000 people). Crude birth rate indicates the number of live births occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
Sex ratio > 15-64 years: The number of males for each female one of five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually it could cause unrest among young adult males who are unable to find partners.

As fertility levels decline, the dependency ratio initially falls because the proportion of youths decreases while the proportion of the population of working age increases. As fertility levels continue to decline, dependency ratios eventually increase because the proportion of the population of working age starts to decline and the proportion of elderly persons continues to increase.
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.

Population density > People per sq. km of land area: Population density (people per sq. km of land area). Population density is midyear population divided by land area in square kilometers. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. In most cases the definition of inland water bodies includes major rivers and lakes.
Age distribution > Population aged 15-64 > Total per thousand people: Number of people aged 15-64. Figures expressed per thousand people for the same year.
Drinking water source > Improved > Total: This entry is derived from People > Drinking water source > Improved, which provides information about access to improved or unimproved drinking water sources available to segments of the population of a country.improved drinking water - use of any of the following sources: piped water into dwelling, yard, or plot; public tap or standpipe; tubewell or borehole; protected dug well; protected spring; or rainwater collection. unimproved drinking water - use of any of the following sources: unprotected dug well; unprotected spring; cart with small tank or drum; tanker truck; surface water, which includes rivers, dams, lakes, ponds, streams, canals or irrigation channels; or bottled water.
Age distribution > Population aged 15-24 > Total per thousand people: Number of people aged 15-24. Figures expressed per thousand people for the same year.
Marriage > Percent married > All > Female > Aged 15-19: Percent of people aged 15-19 years who are or have been married or in a marriage-like union recognized by the law or customs of their country.
Life expectancy at birth > Female: This entry is derived from People > Life expectancy at birth, which contains the average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future. The entry includes total population as well as the male and female components. Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages. It can also be thought of as indicating the potential return on investment in human capital and is necessary for the calculation of various actuarial measures.
Hospital bed density: This entry provides the number of hospital beds per 1,000 people; it serves as a general measure of inpatient service availability. Hospital beds include inpatient beds available in public, private, general, and specialized hospitals and rehabilitation centers. In most cases, beds for both acute and chronic care are included. Because the level of inpatient services required for individual countries depends on several factors - such as demographic issues and the burden of disease - there is no global target for the number of hospital beds per country. So, while 2 beds per 1,000 in one country may be sufficient, 2 beds per 1,000 in another may be woefully inadequate because of the number of people hospitalized by disease.
Marriage, divorce and children > Contraception use among married women > Any method: Current contraceptive use among married women 15-49 years old, any method, percentage.
Contraceptive prevalence rate: This field gives the percent of women of reproductive age (15-49) who are married or in union and are using, or whose sexual partner is using, a method of contraception according to the date of the most recent available data. The contraceptive prevalence rate is an indicator of health services, development, and women’s empowerment. It is also useful in understanding, past, present, and future fertility trends, especially in developing countries.

Urbanization: Estimates and projections of urban and rural populations are made by the Population Division of the United Nations Secretariat and published every two years. These estimates and projections are based on national census or survey data that have been evaluated and, whenever necessary, adjusted for deficiencies and inconsistencies. Urban-rural classification of population in internationally published statistics follows the national census definition, which differs from one country or area to another. National definitions are usually based on criteria that may include any of the following: size of population in a locality, population density, distance between built-up areas, predominant type of economic activity, legal or administrative boundaries and urban characteristics such as specific services and facilities.

Sex ratio > 65 years and over: The number of males for each female one of five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually it could cause unrest among young adult males who are unable to find partners.

Religions: This entry is an ordered listing of religions by adherents starting with the largest group and sometimes includes the percent of total population. The core characteristics and beliefs of the world's major religions are described below.
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.

International migrant stock, total: International migrant stock, total. International migrant stock is the number of people born in a country other than that in which they live. It also includes refugees. The data used to estimate the international migrant stock at a particular time are obtained mainly from population censuses. The estimates are derived from the data on foreign-born population--people who have residence in one country but were born in another country. When data on the foreign-born population are not available, data on foreign population--that is, people who are citizens of a country other than the country in which they reside--are used as estimates. After the breakup of the Soviet Union in 1991 people living in one of the newly independent countries who were born in another were classified as international migrants. Estimates of migrant stock in the newly independent states from 1990 on are based on the 1989 census of the Soviet Union. For countries with information on the international migrant stock for at least two points in time, interpolation or extrapolation was used to estimate the international migrant stock on July 1 of the reference years. For countries with only one observation, estimates for the reference years were derived using rates of change in the migrant stock in the years preceding or following the single observation available. A model was used to estimate migrants for countries that had no data.
