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 2017 Revision of World Population Prospects represents the latest global set of demographic estimates and projections prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. It constitutes the twenty-fifth round of global population estimates and projections produced by the Population Division since 1951. This volume of the 2017 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, regions, subregions, and countries or areas with more than 90,000 inhabitants in 2017. For countries or areas with fewer than 90,000 inhabitants in 2017, only figures related to population size and growth are provided. In all data tables, figures for 1950-2015 are estimates and those thereafter are projections. The projections are presented for the medium, high, low and constant-fertility variants.
