Supercities: problems of urban growth.
The author discusses aspects of urbanization, living conditions in urban centers, and selected policies, summarizing findings from recently published sources. U.N. population projections for selected urban areas for the year 2000 are compared with 1950 estimates, and the proportions of the population living in urban areas in various regions of the world are contrasted. Attention is given to living conditions in rapidly growing and crowded cities, including Mexico City, Mexico; Sao Paulo and Rio de Janeiro, Brazil; Lagos, Nigeria; and Cairo, Egypt. Statements on urban growth issued by the U.N. Fund for Population Activities are considered.
