Population transition  (POPULATION transition)

The process of transition from a situation in which both fertility and mortality were relatively high to one in which they are relatively low which has been observed in many countries, is called the demographic transition 1 or population transition 1. In the process of moving from a pre-transitional stage 2 to a post-transitional stage 3, there is typically a lag between the declines of mortality and fertility, so that a stage of transitional growth 4 of population results. Economists have studied changes in productivity 5, i.e., production per member of the labor force, or per head of the population, associated with this transitional period.

  • 1. Sometimes called the vital revolution. A further distinction is made between the fertility transition and the mortality transition. The theory of the demographic transition associates historical changes in vital rates with socio-economic transformations attending the process of industrialization and urbanization.
