Population: Distribution, Density, Growth, and Composition

#### **Key Points:**

1. **Population Distribution and Density:**

   - **Population Distribution** refers to how population is spread over a region. It is uneven across different parts of the country.

   - **Population Density** is the number of people living per unit area. High density areas in India include the Gangetic plains, coastal plains, and urban regions, while low-density areas include the mountainous regions, deserts, and forests.

2. **Population Growth:**

   - **Population Growth Rate** is the rate at which the number of individuals in a population increases in a given time period.

   - Factors affecting population growth include birth rate, death rate, and migration.

   - India's population growth has seen different phases: 

     - High Growth Phase (1951-1981)

     - Slowing Growth Phase (1981 onwards)

3. **Population Composition:**

   - **Age Composition**: The age structure of a population shows the proportion of individuals of different age groups. It affects the dependency ratio.

   - **Sex Ratio**: The ratio of males to females in a population. India's sex ratio has been skewed towards males.

   - **Rural-Urban Composition**: Differentiates between the rural and urban population. A significant proportion of India's population lives in rural areas.

   - **Literacy Rate**: The percentage of people who can read and write. Literacy rates are higher in urban areas compared to rural areas.

   - **Occupational Structure**: The distribution of the workforce across different sectors like agriculture, industry, and services.

4. **Factors Influencing Population Distribution:**

   - **Physical Factors**: Climate, terrain, soil, availability of water, etc.

   - **Economic Factors**: Employment opportunities, industrialization, urbanization.

   - **Social and Cultural Factors**: Traditions, customs, social structure.

5. **Population Policies:**

   - Government policies aimed at controlling population growth, improving health care, and ensuring sustainable development.
