We do not collect our own population data. Every figure on this dashboard is derived from public datasets published by established international organizations and national statistical offices. Below are the primary sources we use.

Primary Sources

• United Nations Population Division — World Population Prospects. The most widely cited set of historical and projected population figures, including age and sex breakdowns. population.un.org/dataportal
• World Bank Open Data. Country-level population, land area, and demographic indicators, updated annually from national statistical offices. data.worldbank.org
• REST Countries API. Open dataset of country names, codes, areas, and regions used for the country list and flags. restcountries.com
• UNFPA — World Population Dashboard. The category structure of our country health, education and rights indicators follows UNFPA's dashboard, which compiles series from UN agencies. unfpa.org/data/world-population-dashboard
• WHO, UNICEF, UNESCO Institute for Statistics and UNAIDS. Originators of the maternal health, skilled birth attendance, child marriage, school enrolment and HIV figures shown on country pages, retrieved through World Bank Open Data.

What Each Source Provides

• Base population figures: World Bank / UN World Population Prospects.
• Annual growth rates: derived from year-over-year changes in the sources above.
• Age and gender distribution: UN World Population Prospects, with regional profiles where country detail is unavailable.
• Life expectancy, fertility, median age: World Bank and UN demographic indicators.
• Land area and regions: REST Countries API.
• Historical and projected totals by year: UN World Population Prospects (1950–2100).
• Country health, family planning, education, gender and harmful-practice indicators: UN Population Division, WHO, UNICEF, UNESCO and UNAIDS, via World Bank Open Data. Each figure is shown with its reference year; some surveys are several years old.
• Births and deaths today, growth rate (country pages): each country's published crude birth rate, crude death rate and population growth rate.

Update Cadence

The underlying datasets are updated annually by their publishers. Our live counter interpolates between these updates so the number moves continuously. When a new annual revision is published, our base figures are refreshed and the counter adjusts accordingly.
