Provides statistical information on the worldwide population of people 65 years old or older.

The 2015 Revision will build on the previous revision by incorporating the findings of new population censuses and specialized demographic surveys, which have been published since the previous revision. This comprehensive review of worldwide demographic trends and future prospects is essential for assessing the degree of progress made in achieving the Millennium Development Goals (MDGs) and to guide policies aimed at achieving the new post-2015 development agenda, which Member States will adopt this fall. The full results of the 2015 revision will be made available in the form of a two volume report.

This report presents the 2010 Revision of the population estimates and projections prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. The 2010 Revision constitutes the twenty second round of the global population estimates and projections produced by the Population Division since 1951 and it breaks new ground in the production of population projections. For the first time, projections are carried out up to 2100, instead of 2050 as previously. In order to extend the projection period to 2100, a new method for the projection of fertility was developed. The method used in the 2010 Revision is based on the advances made in projecting fertility since the 2000 Revision, advances that have been combined with a probabilistic approach to yield the future paths of fertility used in producing the medium variant of the 2010 Revision. The full results of the 2010 Revision are presented in two volumes. The first

The report presents findings from the 2018 revision of World Urbanization Prospects, which contains the latest estimates of the urban and rural populations or areas from 1950 to 2018 and projections to 2050, as well as estimates of population size from 1950 to 2018 and projections to 2030 for all urban agglomerations with 300,000 inhabitants or more in 2018. The world urban population is at an all-time high, and the share of urban dwellers, is projected to represent two thirds of the global population in 2050. Continued urbanization will bring new opportunities and challenges for sustainable development.

This data booklet summarises and presents key fertility indicators on world fertility patterns from the latest population estimates and projections, World Population Prospects 2015. The relevant data and evidence are made available in an easily accessible manner.
