World Population Prospects 2022
World Population Prospects 2022 is the twenty-seventh edition of the official estimates and projections of the global population that have been published by the United Nations since 1951. They form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. This report provides an overview of global population trends focusing on the period from 1950 to 2050 and presents a summary of key demographic prospects during the second half of the present century.
The United Nations population estimates and projections are used in the calculation of many development indicators used by the United Nations system, including about one-quarter of the indicators used to monitor global progress towards the achievement of the SDGs.
