World Population Prospects: The 2017 Revision, Key Findings and Advance Tables

The 2017 Revision of the World Population Prospects is the twenty-fifth round of 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 of the United Nations Secretariat. The 2017 publication builds on previous revisions by incorporating additional results from the 2010 and 2020 rounds of national population censuses as well as findings from recent specialized sample surveys from around the world. It provides a comprehensive set of demographic data and indicators to assess population trends at the global, regional and national levels and to calculate many other key indicators commonly used by the United Nations system.
