Population in India
Importance of Population
- Population plays a crucial role in the development of the economy and society.
- People are both creators and users of resources.
- Population provides context and meaning to resources, natural events, and disasters.
- The census provides essential data on population numbers, distribution, growth, and characteristics.
Population Size and Distribution
India's Population as of 2011
- Total population: 1.21 billion, 17% of the world's population.
- Uneven distribution across 3.28 million km² (2.4% of the world's area).
- Uttar Pradesh is the most populous state (199 million), while Sikkim (0.6 million) and Lakshadweep (64,429) have much smaller populations.
- Five states (Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Andhra Pradesh) contain almost half of India's population.
- Rajasthan, though the largest by area, has only 5.5% of the population.
Census
- Official population enumeration conducted every ten years (first in 1872, complete in 1881).
- Provides comprehensive demographic, social, and economic data.
Population Distribution by Density
Density Insights
- Population density: number of people per unit area.
- India: one of the most densely populated countries.
- In 2011, population density was 382 persons per sq km.
- High density in Bihar (1,102 persons/sq km), low in Arunachal Pradesh (17 persons/sq km).
- Only Bangladesh and Japan have higher average population densities.
Population Growth and Processes of Population Change
Growth Trends
- Population growth: change in number over time, expressed as absolute numbers or percentage per year.
- Growth rate declining since 1981 due to falling birth rates.
- Despite lower growth rates, absolute increases remain large due to India's massive population base.
Components of Population Change
- Birth rate: live births per thousand persons annually.
- Death rate: deaths per thousand persons annually.
- Migration: movement of people, affecting distribution and composition but not size.
Adolescent Population
- Adolescents (age 10-19) form one-fifth of the population.
- Critical resource for the future; face nutritional challenges.
National Population Policy
- Family Planning Programme initiated in 1952.
- National Population Policy 2000 aims to improve health and welfare through education, immunisation, lowering infant mortality, and promoting delayed marriage.
Migration and Urbanization
- Migration largely rural-to-urban due to rural poverty and urban opportunities.
- Significant increase in cities and towns' population percentage.
Key Terms
- Adolescence: Age 10-19, transitional age group.
- Birth/Death Rate: Number of births/deaths per 1000 people annually.
- Density of Population: People per unit area.
- Migration: Movement of people resulting in population distribution changes.
- National Population Policy: Framework for enhancing health and welfare through family planning and education.
Activities and Exercises
- Tracing family migration patterns.
- Analyzing factors influencing population density.
- Understanding the impact of migration on urban and rural areas.
