About these numbers
Population, growth, birth and death rates, migration, density, age structure, life expectancy, fertility and GDP per capita come from the World Bank Indicators API (latest available year shown beside each figure). The live counter applies the annual growth rate continuously from 1 July 2025 — a model, not a measurement. City populations are the latest census or official estimate held by GeoNames and are not projected. Sub-city units are folded into their parent city.
