Rural and urban population changes and the stages of economic development: a unified approach.

The long-term aspects of the process of economic development and urbanization are examined. A model is presented that shows the dynamics of economic development from the earliest to the more advanced stages. "The model is able to explain not only the occurrence of a downturn in the rural population after the initial phase of population growth both in rural and urban areas, but also the delayed occurrence of such a downturn in many present-day developing countries. The author then focuses [on] the later stages of economic development and explains two alternative courses of urbanization, namely, the reversal process and the continual-growth process, as special cases of the general model; which of the courses occurs depends on the value of the elasticity of urban agglomeration-economies."

Migration and the growth of metropolitan areas in the third world.

"The purpose of the present paper [is] to investigate further the role of migration in developing countries by analyzing the components of population growth in 26 large metropolitan areas in Africa, Asia, and Latin America." The process of urban population growth is first described. Then, using data from censuses and official U.N. sources, the author examines the relative importance of migration and natural increase in urban growth and in the growth of the largest urban areas. The focus is primarily on the period 1960-1970. Consideration is also given to "estimates of the natural increase of migrants after their arrival in the city in order to assess the full effect of net migration on metropolitan growth, analyses of the relationships between the components of growth and several structural variables and, finally, a discussion of the results." The importance of migration as a factor affecting urban growth is noted.

Urbanization and internal migration.

This is a survey of the U.N. Population Division's contributions to the study of urbanization and internal migration, related research, and publications. In order to review these contributions, the relevant U.N. publications are classified under five broad topics: "estimates and projections of urban, rural and city populations, including problems of data comparability and methods to measure internal migration; monitoring of trends in urbanization; estimates and analyses of migration as a component of urban and metropolitan growth; studies of demographic and socio-economic aspects of urbanization, and studies of demographic and socio-economic aspects of internal migration."
