- 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.
- 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. 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.

- 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.
- 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.
- 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.
- 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.
- Ethnic groups: This entry provides a rank ordering of ethnic groups starting with the largest and normally includes the percent of total population.
- 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.
- 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.

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.
Additional details:- Gibraltar: above 80% (2013)
- Marriage > Years being single before marriage > Women: Average age of women at their first marriage.
- Marriage, divorce and children > Marriages: Marriages by urban/rural residence.
- Marriage, divorce and children > Marriages per thousand people: Marriages by urban/rural residence. Figures expressed per thousand people for the same year.
- Marriage, divorce and children > Total divorces: Total number of divorces in given year by country.
- Marriage, divorce and children > Total divorces per thousand people: Total number of divorces in given year by country. Figures expressed per thousand people for the same year.
- 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.
- 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).
- Nationality > Adjective: This entry is derived from People > Nationality, which provides the identifying terms for citizens - noun and adjective.
- Nationality > Noun: The noun which identifies citizens of the nation
- 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.
- 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.

- Population: Population, total refers to the total population.
- 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.
- Population > Population growth, past and future: Population growth rate (percentage).
- Population density: 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."
- 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.
- Population in 2015: (Thousands) Medium-variant projections.
- 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.

- 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.
- Urban and rural > Population living in cities proper: Each city population by sex, city and city type.
- Urban and rural > Rural population: Total population living in rural areas by country.
- Urban and rural > Urban population: Total population living in urban areas by country.
- 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.
