Some models for patterns of urbanization, migration and development.

"This paper aims to study the pattern of urbanization and the evolution of [the] relationship between rural-urban migration and the degree of economic development taking Gross National Product...into consideration. Intercensal age-specific rural net out-migration rates are also estimated from [tabulations] of the proportion of rural population of India by age through a recently developed procedure based on generalized stable population by Stupp (1989). A comparative study is also made between [the] survival column of India with a developed nation like Japan."
