This volume of the 2015 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, major areas, regions, and countries or areas with more than 90,000 inhabitants in 2015. For countries or areas with fewer than 90,000 inhabitants in 2015, 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 medium, high, low and constant-fertility variants. The tables are accompanied by an executive summary.
