Population Size and Distribution
India's Population Size and Distribution by Numbers
- As of March 2011, India's population was 1,210.6 million which accounts for 17.5% of the world's population.
- Uttar Pradesh is the most populous state of India as it counts about 16% of the country's population.
- Almost half of India's population lives in just five states which are Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Andhra Pradesh.
India's Population Distribution by Density
Population Density is calculated as the number of persons per unit area. The population density of India in the year 2011 was 382 persons per sq km. That's why India is considered one of the most densely populated countries in the world.
Population Growth and Processes of Population Change
The numbers, distribution, and composition of the population are constantly changing. This is the influence of the interaction of the three processes:
- Birth
- Death
- Migration
Population Growth
Growth of population refers to the change in the number of inhabitants of a country/territory during a specific period. This change can be expressed in 2 ways:
- In terms of absolute numbers: The absolute numbers are obtained by subtracting the earlier population (e.g. that of 2001) from the later population (e.g. that of 2011).
Processes of Population Change/Growth
Three main processes of change of population are:
1) Birth Rates: Birth rate is the number of live births per thousand persons in a year. In India, birth rates have always been higher than death rates.
2) Death Rates: The death rate is the number of deaths per thousand persons in a year.
3) Migration: Migration is the movement of people across regions and territories. Migration can be internal (within the country) or international (between the countries). It influences the distribution of population within the nation. In India, the rural-urban migration has resulted in a steady increase in the percentage of the population in cities and towns.

Age Composition
The age composition of a population refers to the number of people in different age groups in a country. The population of a nation is grouped into 3 broad categories:
1) Children (generally below 15 years): They are economically unproductive and need to be provided with food, clothing, education, and medical care.
2) Working Age (15–59 years): They are economically productive and biologically reproductive. They comprise the working population.
3) Aged (Above 59 years): They may be working voluntarily but they are not available for employment through recruitment.
Sex Ratio
It is defined as the number of females per 1000 males in the population. Sex Ratio is an important social indicator to measure the extent of equality between males and females in a society at a given time.
Literacy Rates
According to the Census 2011, a person aged 7 years and above, who can read and write with understanding in any language, is treated as literate. India's literacy rate is 73% as per the census of 2011.
Occupational Structure
The distribution of the population according to different types of occupation is referred to as the occupational structure. Occupations are classified as:
- Primary: Primary activities include agriculture, animal husbandry, forestry, fishing, mining, quarrying, etc
- Secondary: Secondary activities include the manufacturing industry, building and construction work, etc.
- Tertiary: Tertiary activities include transport, communications, commerce, administration, and other services.
