The World Population Data Sheet lists all geopolitical entities with populations of 150,000 or more and all members of the United Nations, including sovereign states, dependencies, overseas departments, and some territories whose status or boundaries may be undetermined or in dispute. For simplicity, this tool refers to all geopolitical entities as “countries.”
Each indicator’s definition is listed alongside the data.
The rates and figures are primarily compiled from the following sources: online databases, reports, and other materials from national statistical offices and regional organizations; population and health surveys such as the Demographic and Health Surveys (DHS), Multiple Indicator Cluster Surveys (MICS), and Performance Monitoring for Action (PMA) surveys; the UN Demographic Yearbook 2022 and Population and Vital Statistics Report, vol. LXXVI (January 2024) of the UN Statistics Division; World Population Prospects: The 2024 Revision, World Contraceptive Use 2022, and World Urbanization Prospects: The 2018 Revision of the UN Population Division; the International Database of the International Programs Center, U.S. Census Bureau; and World Development Indicators online database of the World Bank.
Sources also include direct communication with national statistical offices, demographers, and country experts from around the world. Specific data sources may be obtained by contacting the authors of the 2024 World Population Data Sheet.
Demographic rates for countries with complete vital registration are those most recently reported. For more-developed countries, the rates refer to 2023 or 2022. For other indicators, see Definitions for data years.
Regional population totals are independently rounded and include small countries or areas not shown. Regional and world rates are weighted averages of countries for which data are available. Regional averages are shown when data or estimates are available for at least three-quarters of the region’s population.
More-developed, less-developed, and least-developed regions follow the UN classification (UN OHRLLS).
High-income, middle-income (composed of upper middle-income and lower middle-income), and low-income economies follow the World Bank classification based on GNI per capita (World Bank).
