6 POPULATION C an you imagine a world without human beings? Who would have utilised the resources and created social and cultural environment? The people are important to develop the economy and the society. The people make and use resources and are themselves resources with varying quality. Coal is but a piece of rock, until people were able to invent technology to obtain it and make it ‘resource’. Natural events, like a flood or a Tsunami, becomes a ‘disaster’ only when they affect a crowded village or a town. Hence, population is the pivotal element in social studies. It is the point of reference from which all other elements are observed and from which they derive significance and meaning. ‘Resources’, ‘calamities’ and ‘disasters’ are all meaningful only in relation to human beings. Their numbers, distribution, growth and characteristics or qualities provide the basic background for understanding and appreciating all aspects of the environment. Human beings are producers and consumers of earth’s resources. Therefore, it is important to know how many people are there in a country, where do they live, how and why their numbers are increasing and what are their characteristics. The census of India provides us with information regarding the population of our country. POPULATION S IZE AND D ISTRIBUTION India’s Population Size and Distribution by Numbers India’s population as on March 2011 stood at 1,210.6 million, which account for 17.5 per cent of the world’s population. These 1.21 billion people are unevenly distributed over our country’s vast area of 3.28 million square km, which accounts for 2.4 per cent of the world’s area (Figure 6.1). The 2011 Census data reveal that Uttar Pradesh with a population size of 199 million is the most populous state of India. Uttar Pradesh accounts for about 16 per cent of the country’s population. On the other hand, the Himalayan state of Sikkim has a population of just about 0.6 million and Lakshadweep has only 64,429 people. Almost half of India’s population lives in just five states. These are Uttar Pradesh, Maharashtra, Bihar, West Bengal and Andhra Pradesh. Rajasthan, the biggest state in terms of area, has only 5.5 per cent of the total population of India (Figure 6.2) What could be the reason of uneven distribution of population in India? Census A census is an official enumeration of population done periodically. In India, the first census was held in the year 1872. The first complete census, however, was taken in the year 1881. Since then, censuses have been held regularly every tenth year. The Indian Census is the most comprehensive source of demographic, social and economic data. Have you ever seen a census report? Check in your library if it has one. 48 CONTEMPORARY INDIA-I Rationalised 2023-24 India’s Population Distribution by Density POPULATION Population density provides a better picture of the uneven distribution. Population density is calculated as the number of persons per unit area. India is one of the most densely populated countries of the world. Rest of the world, 82.5% India, 17.5% Only Bangladesh and Japan have higher average population densities than India. Find out the population densities of Bangladesh and Japan. Do You Know AREA Rest of the world, 97.6% India, 2.4% Fig 6.1 : India’s Share of World’s Area and Population The population density of India in the year 2011 was 382 persons per sq km. Densities vary from 1,102 persons per sq km in Bihar to only 17 persons per sq km in Arunachal Pradesh. A study of the Figure 6.3 shows the pattern of uneven distribution of population densities at the State level.

Do you find any corelation between these maps? Note the States with population densities below 250 persons per square km. Rugged terrain and unfavourable climatic conditions are primarily responsible for sparse population in these areas. Which states have density below 250 persons per square km? Assam and most of the Peninsular states have moderate population densities. Hilly, dissected and rocky nature of the terrain, moderate to low rainfall, shallow and less fertile soils have influenced population densities in these areas. The Northern plains and Kerala in the south have high to very high population densities because of the flat plains with fertile soils and abundant rainfall. Identify the three states of the Northern Plains with high population densities. POPULATION GROWTH AND PROCESSES POPULATION CHANGE OF Population is a dynamic phenomenon. The numbers, distribution and composition of the population are constantly changing. This is the influence of the interaction of the three processes, namely — births, deaths and migrations. Population Growth Growth of population refers to the change in the number of inhabitants of a country/territory during a specific period of time, say during the last 10 years. Such a change can be expressed in two ways: in terms of absolute numbers and in terms of percentage change per year. The absolute numbers added each year or decade is the magnitude of increase. It is obtained by simply subtracting the earlier population (e.g. that of 2001) from the later population (e.g. that of 2011). It is referred to as the absolute increase. The rate or the pace of population increase is the other important aspect. It is studied in per cent per annum, e.g. a rate of increase of 2 per cent per annum means that in a given year, there was an increase of two persons for every 100 persons in the base population. This is referred to as the annual growth rate. India’s population has been steadily increasing from 361 million in 1951 to 1210 million in 2011. Table 6.1 : The Magnitude and Rate of India’s Population Growth Year Total Population (in million) Absolute Increase in the Decade (in million) Annual Growth Rate (%) 1951 1961 1971 1981 1991 2001 2011 361.0 439.2 548.2 683.3 846.4 1028.7 1210.6 42.43 78.15 108.92 135.17 163.09 182.32 181.46 1.25 1.96 2.20 2.22 2.16 1.97 1.64 Table 6.1 and Figures 6.4 (a) and 6.4 (b) reveal that from 1951 to 1981, the annual rate of population growth was steadily increasing; which explains the rapid increase in population from 361 million in 1951 to 683 million in 1981. Table 6.1 reveals that despite the decline in growth rates, the number of people being added every decade is steadily increasing. Why? Since 1981, however, the rate of growth started declining gradually. During this period, birth rates declined rapidly. Still 182 million people were added to the total population in the 1990s alone (an annual addition larger than ever before). It is essential to realise that India has a very large population. When a low annual rate is applied to a very large population, it yields a large absolute increase. When more than a billion people increase even at a lower rate, the total number being added becomes very large. India’s annual increase in population is large enough to neutralise efforts to conserve the resource endowment and environment. The declining trend of the growth rate is indeed a positive indicator of the efforts of birth control. Despite that, the total additions to the population base continue to grow, and India POPULATION 51 Rationalised 2023-24 Fig. 6.4(a): India’s Population Growth Rates during 1951-2011 Fig. 6.4(b): India’s Population 1901-2011 may overtake China in 2045 to become the most populous country in the world. Processes of Population Change/Growth There are three main processes of change of population : birth rates, death rates and migration. The natural increase of population is the difference between birth rates and death rates. Birth rate is the number of live births per thousand persons in a year. It is a major component of growth because in India, birth rates have always been higher than death rates. 52 CONTEMPORARY INDIA-I Rationalised 2023-24 Death rate is the number of deaths per thousand persons in a year. The main cause of the rate of growth of the Indian population has been the rapid decline in death rates. Till 1980, high birth rates and declining death rates led to a large difference between birth rates and death rates resulting in higher rates of population growth. Since 1981, birth rates have also started declining gradually, resulting in a gradual decline in the rate of population growth. What are the reasons for this trend? The third component of population growth is migration. Migration is the movement of people across regions and territories. Migration can be internal (within the country) or international (between the countries). Internal migration does not change the size of the population, but influences the distribution of population within the nation. Migration plays a very significant role in changing the composition and distribution of population. Activity On a map, trace the migration of each of your grandparents and parents since their birth. Try and analyse the reasons for each move. population in 1951 to 31.80 per cent in 2011. There has been a significant increase in the number of ‘million plus cities’ from 35 to 53 in just one decade, i.e., 2001 to 2011. Adolescent Population The most significant feature of the Indian population is the size of its adolescent population. It constitutes one-fifth of the total population of India. Adolescents are, generally, grouped in the age group of 10 to 19 years. They are the most important resource for the future. Nutrition requirements of adolescents are higher than those of a normal child or adult. Poor nutrition can lead to deficiency and stunted growth. But in India, the diet available to adolescents is inadequate in all nutrients. A large number of adolescent girls suffer from anaemia. Their problems have so far not received adequate attention in the process of development. The adolescent girls have to be sensitised to the problems they confront. Awareness among them can be improved through the spread of literacy and education. National Population Policy In India, most migrations have been from rural to urban areas because of the “push” factor in rural areas. These are adverse conditions of poverty and unemployment in the rural areas and the “pull” of the city in terms of increased employment opportunities and better living conditions. Migration is an important determinant of population change. It changes not only the population size but also the population composition of urban and rural populations in terms of age and sex composition. In India, the rural-urban migration has resulted in a steady increase in the percentage of population in cities and towns. The urban population has increased from 17.29 per cent of the total Recognising that the planning of families would improve individual health and welfare, the Government of India initiated a comprehensive Family Planning Programme in 1952. The Family Welfare Programme has sought to promote responsible and planned parenthood on a voluntary basis. The National Population Policy (NPP) 2000 is a culmination of years of planned efforts. The NPP 2000 provides a policy framework for imparting free and compulsory school education up to 14 years of age, reducing infant mortality rate to below 30 per 1000 live births, achieving universal immunisation of children against all vaccine preventable diseases, promoting delayed marriage for girls, and making family welfare a people-centred programme.
