Question

The components of population composition differ greatly from one country to another and from time to time. Discuss population composition in brief

Answer 1

Explanation:

India, China, and the United States are all undergoing major demographic and spatial transformations. The form of these transformations varies widely—not only among the three nations, but also within various regions of the three countries. Some major patterns are apparent, however, when the three countries and the six study regions in them (Kerala, India; Haryana, India; the Jitai Basin, China; the Pearl River Delta, China; South Florida, USA; and Chicago, USA) are compared on several dimensions: changes in the rates and components of population increase, geographic redistribution of the population, and the influences of external economic and demographic events.

Are the net effects of population growth positive (Simon, 1981) or negative (Ehrlich, 1968)? Does population growth cause innovation (Boserup, 1965)? Is population growth the major factor in environmental degradation, or does it play only a secondary role after factors such as economic development, consumption, and public policy (Jolly and Torrey, 1993; Meyer and Turner, 1992)?

In some of these interactions population can best be viewed as the independent variable; in other contexts it must be viewed as the dependent variable. It is this complexity that makes analysis in the field both frustrating and exciting.
