1950 CE: ~360-410 million (14-16% of world population)
1970 CE: ~550-600 million (15-16% of world population)
1990 CE: ~900-950 million (17-18% of world population)
2010 CE: ~1.2-1.3 billion (18-19% of world population)
2020 CE: ~1.4-1.5 billion (18-19% of world population)

Population Growth Rates

1945-1970 CE: 1.5-2.0% annual growth (high)
1970-1990 CE: 2.0-2.5% annual growth (very high)

Post-Independence Period (1945-1970 CE)

Rapid Growth: High population growth rates
Health Improvements: Improving life expectancy, disease control
Fertility: High fertility rates (5-6 children per woman)
Mortality: Declining mortality rates

Demographic Transition (1970-1990 CE)

Continued Growth: Very high population growth
Fertility Decline: Beginning of fertility decline
Urbanization: Rapid urbanization
Migration: Internal migration, urbanization

Modern Period (1990-2020 CE)

Slowing Growth: Declining growth rates
Fertility Decline: Continued fertility decline (2-3 children per woman)
Aging: Beginning of population aging
