May 16 (UPI) -- Two-thirds of the world's population will live in urban areas by 2050, a United Nations report on sustainable urban planning said Wednesday.
The Revision of World Urbanization Prospects report, by the U.N. Department of Economic and Social Affairs, says 35 percent of the projected growth of the world's urban population between 2018 and 2050 will be in only a few countries -- notably China, India and Nigeria.
