India has witnessed significant population growth since 1921, driven by various socio-economic factors. Key stages of this growth include:
1. Early Growth (1921-1950): India's population grew slowly due to high mortality rates and lower life expectancy during this period.
2. Post-Independence Growth (1950-1980): After independence, India’s population growth surged due to improved healthcare, nutrition, and sanitation.
3. Modern Growth (1980-Present): The population continued to grow rapidly, although the growth rate has slowed in recent decades due to family planning policies and urbanization.
4. Urbanization and Migration: A significant shift from rural to urban areas has contributed to increased population density in cities.
