World Urbanization Prospects: The 2018 Revision

image of World Urbanization Prospects: The 2018 Revision

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.

Urban and rural population size and growth at the country level

The previous chapter highlighted the similarities and differences across geographic regions and income groups with respect to the levels and trends of urbanization since 1950, as well as projections to 2050. While that broad aggregate analysis provides a useful summary of the past and future patterns of urbanization, it tends to disguise the considerable variation in the urban transition experience that exists across countries within geographic regions and income groups. To describe that variability, this chapter undertakes an analysis of country-level trends estimated from 1950 to 2018 and projected to 2050. Section A addresses the level of urbanization; section B describes the size and growth of the urban and rural populations; and section C summarises the rate of urbanization (the average annual rate of change of the percentage urban). Results highlight the substantial degree of heterogeneity in the past and future trends of urbanization both across and within geographic regions and income groups.
