About World Population: Estimates & Projections

The United Nations Population Division biennially prepares the official United Nations population estimates and projections for countries, their urban and rural areas, and their major cities for all countries and areas of the world. These population estimates and projections provide the standard and consistent set of population figures which are used throughout the United Nations system as the basis for activities requiring population information as an input.

In particular, these population figures provide the "denominators" for the regular estimates and projections exercises undertaken by the specialized agencies in sectors such as labour force, school enrolment and agriculture. The Population Division, the regional commissions, specialized agencies and other organizations within the United Nations system that regularly make use of these estimates and projections (particularly for the preparation of the above-mentioned population-based sectoral estimates and projections) meet every two years, under the auspices of the Administrative Committee on Co-ordination (ACC), to organize work and to maintain consistency among the United Nations population and sectoral estimates and projections.

A second aspect of the population estimates and projections work programme is preparation of consistent estimates and projections of the urban and rural populations for all countries and areas of the world. Estimates and projections of urban and rural populations cover the period of 1950 to 2030 and are revised biennially.

Thirdly, the Population Division prepares the United Nations estimates and projections of populations of urban agglomerations and of capital cities. These urban agglomerations estimates and projections cover the period from 1950 to 2015. The full results are published in the same monograph as the urban projections.

The Population Division also prepares, from time to time, supplementary world population projections, extending the regular projections into the "long term". The latest such projections, published in 1998, presents seven scenarios of population projections to the year 2150 for large areas of the world appeared in World Population Projections to 2150.
