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."
