The global phenomena of city growth stimulate increasing interest in urbanism as a world-permeating way of life. Urbanization, seen as the movement of people into industry and cities and reflective of urbanism, has received considerable demographic attention. But the research fails to include some pertinent phases of urbanization. Demography can supplement this, but it must also be supplemented by other types of research; the latter develops slowly. Urbanism theory, developed mainly in the more advanced countries, waits to be tested in those regions where the urban way of life is only now taking form and where seasoned research into its processes is needed.
