The United Nations estimated the world’s population would hit 8 billion people on Nov. 15, 2022 and that it would climb to 10.4 billion by the end of the century. According to the World Bank, 56 percent of the world’s population now lives in cities or urban areas and that trend is expected to continue with urban populations more than doubling its current size by 2050 to a point at which nearly 70 percent of the world’s population will live in urban areas.
