The estimates are based on official statistics on the foreign-born or the foreign population, classified by sex, and age. Most of the statistics utilised to estimate the international migrant stock were obtained from population censuses. Additionally, population registers and nationally representative surveys provided information on the number and composition of international migrants.

The 2022 Revision of World Population Prospects is the twenty-seventh edition of official United Nations population estimates and projections that have been prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat.

For the systematic tracking of levels and trends in urbanization throughout the world, the Population Division of the Department of Economic and Social Affairs of the United Nations has issued a recurrent series, known as World Urbanization Prospects, since 1988. The series provides estimates and projections of the size of the urban and rural populations of all countries and of the populations of cities or urban agglomerations above a threshold of 300,000 inhabitants. Today, we are releasing the results of the 2018 Revision of World Urbanization Prospects.

The 2018 Revision of World Urbanization Prospects presents the latest United Nations estimates of the size of urban and rural populations for 233 countries or areas from 1950 to 2018, with projections until 2050. It also includes data on population size for close to 1900 urban settlements having 300000 inhabitants or more in 2018. These 1900 cities or urban areas are now home to nearly 60 per cent of the world’s urban population.
