About the product
The United Nations population estimates and projections form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. The 2019 revision of the World Population Prospects is the twenty-sixth edition of the official United Nations population estimates and projections, which have been prepared since 1951 by the Population Division of the Department of Economic and Social Affairs. The 2019 revision presents population estimates from 1950 until the present for 235 countries or areas, which have been developed through country-specific analyses of historical demographic trends. It builds on previous revisions by incorporating additional results from the 2010 and 2020 rounds of national population censuses as well as information from vital registration and recent nationally representative household sample surveys. The 2019 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels. This volume of the 2019 Revision presents the comprehensive tables of the official United Nations population estimates and projections, displaying key demographic indicators for selected periods or dates from 1950 to 2100, for the world, development groups, income groups, regions, subregions, and countries or areas with more than 90,000 inhabitants in 2019. For countries or areas with fewer than 90,000 inhabitants in 2019, only figures related to population size and growth are provided. In all data tables, figures for 1950 2020 are estimates and those thereafter are projections. The projections are presented for the medium fertility variant, lower and upper 95 per cent prediction intervals, and constant-fertility variant.
