Most of the nations of Africa and Asia remain predominantly rural and agricultural. However, more than half the people in most Latin American countries are no longer rural, and a fifth to a third live in cities of 100,000 or more. In Asia and North Africa, Lebanon, the U.A.R., and the Philippines are also substantially urbanized, and Morocco, Syria, Turkey, South Korea, and Taiwan are not far behind. Moreover, virtually everywhere in the developing world, regardless of the extent of urbanization already achieved, cities are growing at rates of 5 to 8 percent annually. That is, they are doubling their populations every ten to fifteen years.
