Demographic Transition Model

Def and theorist?

Warren Thompson: in places where industrialization had succeeded it will fundamentally affect lower birth and death rates

Stage 1

Low Growth Rates: living condition caused rates to fluctuate. The agricultural revolution during 8000 BC increased food production which met famine, disease, and war. Extra kids meant extra help with labor.

Stage 2

High Growth Rate: The Industrial Revolution brought growth in all sectors and a rapid decline in the death rate. The medical revolution occurred when vaccines were brought to LDC.

Current countries: Sub-Saharan Africa, Middle East, Pacific Islands

Stage 3

Moderate Growth: Occurs when birth rates drops faster than death rates. There’s a decreases in infant mortality, children are financial burdens, women have more rights

Current Countries: Latin America, East and South East Asia

Stage 4

Low Growth Rate: When nations hit zero population growth where birth rates equal death rates. There are high costs of childcare and college. A great strain on social security programs b/c young people are trying to support older citizens who are no longer working

Current Countries: Europe, Japan, Brazil, Singapore

“Stage 5”

Population Collapse: Demographers worry about rapid growth of population and strains gov. and natural resources. Low birth and death rates and a decrease in population. Gov. increases incentives to increase B.R. The mortality rate is greater than B.R.
