Understanding population trends and anticipating demographic change are crucial for national development planning and for implementing the 2030 Agenda for Sustainable Development. Countries, where population growth has slowed or stopped, must prepare for an increasing proportion of older persons and, in some cases, decreasing population size. These and other challenges can be addressed in part by responding to future demographic trends and incorporating that information into policies and planning.
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.
