Figures use the Medium variant of the 2024 Revision. The UN series covers 237 countries or areas; estimates and projections from 1950 to 2100 and is built from 1,910 population censuses and 3,189 nationally representative sample surveys, alongside vital-registration and other demographic systems.
These are demographic estimates and projections for the downloadable population selection, not a live register of identifiable people. Mid-year values refer to 1 July; moving counters interpolate a published annual flow between anchors.
