This paper examines some of the characteristics of world's population mobility, cultural environment and changin societies. Some of the national and international problems associated with population data collection and enumeration are explored including transient and temporary population movements. In analyzing population mobility and demographic transition, Zelinky's hypothesis is used as a conceptual framework applicable in both Developed and Developing countries. The findings of the study focused mainly on some of government policies and implications essential for rural-orientated and urban-orientated development programmes. It is emphasized that to achieve some of the socio-economic development objectives in any nation, it is important to have a comprehensive understanding of all the processes of mobility to match the various government policies of the redistribution.
