Two theories of population growth and population flow are the demographic Transition Theory and Theories of Factors Behind Global Migration. Explain and discuss Demographic Transition Theory and Factors Behind Global Migration proposed by Joseph J. Splenger, Everette Lee, David Heer and the structuralist.

Answer 1

1- Demographic transition theory-

The theory reflects the transition of the high birth rates and high infant death rates in the context of technology laggardness to low birth rates and infant death rates allied with better and deeper technology rooted facets.

The pre industrial society, agricultural revolution are the significant adjacent parameters to this theory.

Further, the way food was handled, personal/ individual hygiene, water distribution facilities, and disposal mechanism for sewage have been the indicators in demographic transition theory.

The model can be utilised to comprehend the journey of countries from being less industrialized to get cultivated into industrialised ones.

Population growth is almost null in post industrialised societies.

2- Theory of factors behind global migration-

Skilled jobs, unskilled jobs, higher education, trade opportunities, space for expansion of the business are the root reasons/ factors behind global migration.

This theory also points towards the cheap labour as a crucial attribute allied with the global migration.

Investment by the capitalistic nations into the poor/ bottom of pyramid nations, too, triggers the migration.
