Statistical definitions of urban population and their uses in applied demography

Among the most significant changes now affecting all mankind is the ever-increasing concentration of population in special areas, sometimes entire regions which, from a variety of standpoints, are regarded as "urban". It has been estimated, for instance, that the world's "urban" population-as each country may define it-totalled 360 million in 1920 and about 1000 million in 1960 while by this century's end it may surpass 3000 million. Such a drastic transformation of the human habitat has farreaching implications for the organization and development of almost every sphere of collective life and, for these reasons, requires painstaking demographic study.
