NCERT Explained: Class IX Geography, Chapter 6 - Population: Understanding India’s People

Introduction to the Topic

When we look at a map of India, we see diverse landscapes—mountains, plains, plateaus, and coasts. However, the most important element that makes a nation is its people. People are the ones who utilize resources and create social and cultural environments. They are both producers and consumers of resources. Therefore, understanding the population of a country is essential to understanding its development and future potential.

In Class IX Geography, Chapter 6, titled 'Population', we delve into the three major aspects of the human resource: population size and distribution, population growth and processes of population change, and the qualities or characteristics of the population. This chapter helps students understand that people are not just numbers; they are the most significant resource of a country.

Key Concepts Explained

1. Population Size and Distribution

India’s population is one of the largest in the world. According to the 2011 Census, India’s population stood at 1,210.6 million (1.21 billion). To put this in perspective, India accounts for 17.5 percent of the world's population, but only occupies 2.4 percent of the world's total land area. This highlights the high pressure on our natural resources.

Distribution by State: Population is not spread evenly across the country. Uttar Pradesh is the most populous state in India, accounting for nearly 16 percent of the country's population. On the other hand, states like Sikkim have very low populations (only about 0.6 million), and the Union Territory of Lakshadweep has only a few thousand people. Almost half of India's population lives in just five states: Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Andhra Pradesh.

Population Density: Population density is calculated as the number of persons per unit area. It gives us a better picture of how crowded a place is. India is one of the most densely populated countries in the world. As per 2011 data, the density was 382 persons per square km. However, this varies greatly. For example, Bihar has a density of 1,102 persons per sq km, while Arunachal Pradesh has only 17 persons per sq km. Factors like climate, terrain (hilly vs. flat), and availability of water influence these numbers.

2. Population Growth and Processes of Population Change

Population is a dynamic phenomenon. The numbers, distribution, and composition are constantly changing. There are three main processes that drive these changes: births, deaths, and migration.

• Birth Rate: This is the number of live births per thousand persons in a year. In India, birth rates have historically been higher than death rates, leading to population growth.
• Death Rate: This is the number of deaths per thousand persons in a year. A significant decline in death rates (due to better medical facilities and food security) is a primary reason for the rapid growth of India’s population in the 20th century.
• Migration: This refers to the movement of people across regions and territories. Migration can be internal (within the country) or international (between countries). While internal migration does not change the size of the national population, it significantly influences the distribution of population within the nation. In India, the 'push' factor of rural poverty and the 'pull' factor of urban employment opportunities drive people from villages to cities.

Growth of Population: Growth of population refers to the change in the number of inhabitants of a country/territory during a specific period of time (usually 10 years). We calculate this in two ways: absolute increase (subtracting the earlier population from the later) and annual growth rate (percentage increase per year).

3. Characteristics or Qualities of the Population

To understand the 'quality' of our human resource, we look at several demographic indicators:

• Age Composition: The population is generally divided into three categories: Children (below 15 years), who are economically dependent; Working Age (15-59 years), who are the productive part of the population; and Aged (above 59 years), who may be retired but are part of the dependent group. A large percentage of children and aged people means a higher dependency ratio.
• Sex Ratio: This is defined as the number of females per 1000 males. It is a crucial social indicator to measure the extent of equality between males and females in a society. In 2011, the sex ratio in India was 943. Some states like Kerala have a sex ratio of 1084 (favorable to females), while others like Haryana have much lower ratios.
• Literacy Rates: Literacy is a prerequisite for economic and social development. According to the Census of 2011, a person aged 7 years and above who can read and write with understanding in any language is considered literate. India's literacy rate in 2011 was 73 percent (80.9% for males and 64.6% for females).
• Occupational Structure: This refers to the distribution of the population according to different types of occupations. These are categorized into Primary (agriculture, mining), Secondary (manufacturing), and Tertiary (services, transport, banking). In developing countries like India, a large proportion of the population is still engaged in primary activities.
• Health: Health is an indispensable component of individual development. While India has made significant strides in life expectancy (which rose from 36.7 years in 1951 to 67.9 years in 2012), challenges like malnutrition and lack of safe drinking water in rural areas remain.

4. Adolescent Population and National Population Policy

Adolescents (aged 10 to 19 years) constitute about one-fifth of India's total population. They are the most important resource for the future. However, their nutritional requirements are higher than those of children, and many adolescent girls in India suffer from anemia. The National Population Policy (NPP) 2000 was formulated to address these issues. Its objectives include providing a policy framework for imparting free and compulsory school education up to 14 years of age, reducing infant mortality, achieving universal immunization of children, and promoting delayed marriage for girls.

Summary & Key Takeaways

• People as Resources: Humans are the most vital resource for any nation's development.
• Census: A census is an official enumeration of population done periodically (every 10 years in India).
• Uneven Distribution: Population is concentrated in fertile plains and coastal areas, while mountains and deserts are sparsely populated.
• Components of Change: Birth rate, death rate, and migration are the three pillars of population change.
• Dependency Ratio: India has a large working-age population, which is an economic advantage (often called the demographic dividend).
• Social Indicators: Literacy and sex ratio are key measures of a society's health and progress.
• Policy Focus: The NPP 2000 focuses on health, education, and empowering the youth to ensure a stable and productive population.
