Overview
The chapter explains how population is distributed, how it changes over time, and why demographic structure is important for planning.
Learning Objectives
- Describe population distribution and density
- Explain population growth and its components
- Interpret age structure and dependency ratio
Key Concepts
Population Distribution
Population is concentrated in plains and coastal areas due to fertile soil, water availability, and economic opportunities.
Factors Affecting Distribution
Relief, climate, water availability, jobs, and transport shape where people live.
Population Density
Density measures people per unit area and varies widely across India.
Population Change Over Time
Historical events, health facilities, and migration trends influence growth rates in different periods.
Population Growth
Growth depends on birth rate, death rate, and migration patterns.
Age Composition
A large working-age population can boost the economy, while high dependency ratios increase social burden.
Literacy and Health
These indicators reflect human development and quality of life.
Key Terms
Examples
High Density in Plains
Northern Plains support high densities due to fertile land and river systems.
Low Density in Himalayas
Rugged terrain and harsh climate limit settlement in mountainous regions.
