Class 12 Sociology notes on The Demographic Structure of the Indian Society: demography concepts, Malthusian theory, demographic transition, sex ratio, literacy and…
Demography is the systematic study of population — its size, growth, composition and the processes of birth, death and migration that shape it. This chapter explains why demography matters so much to sociology, and then applies demographic ideas to India. You will learn the two classic theories of population growth, the Malthusian theory and the theory of demographic transition, and the basic tools demographers use: birth rate, death rate, fertility rate, infant and maternal mortality, life expectancy, sex ratio, age structure and dependency ratio. The chapter then traces the size and growth of India's population through the twentieth century, the reasons death rates fell while birth rates stayed high, the sharp decline in the sex ratio, patterns of literacy, rural-urban differences and urbanisation, and India's population policy from 1952 to the present.

What Demography Is and Why Sociology Needs It
Demography comes from the Greek words demos (people) and graphein (describe), so it literally means the description of people. It studies changes in population size, patterns of births, deaths and migration, and the composition of the population by sex and age group. Formal demography is largely quantitative and uses mathematical methods to measure and forecast population change, while social demography or population studies asks about the wider social, economic and political causes and consequences of population trends. All demographic work rests on counting exercises such as the census or the survey. The chapter notes that sociology and demography grew together in eighteenth-century Europe, when nation-states needed regular social statistics, and that aggregate statistics like the death rate are social facts that must be explained socially, as Emile Durkheim showed in his study of suicide rates.

The Malthusian Theory of Population Growth
Thomas Robert Malthus (1766–1834), an English political economist, set out a pessimistic theory in his Essay on Population (1798). He argued that population tends to grow in geometric progression (2, 4, 8, 16, 32 …) while the means of subsistence, especially food, can grow only in arithmetic progression (2, 4, 6, 8, 10 …). Since population growth always outstrips the growth of food supply, humanity is condemned to poverty unless population growth is controlled. Malthus thought voluntary 'preventive checks' such as postponing marriage, sexual abstinence or celibacy had only limited scope, so 'positive checks' like famines and diseases were inevitable — nature's way of restoring the balance. His theory was later refuted: European birth rates declined and epidemic diseases were controlled, and both food production and standards of living rose despite rapid population growth. Liberal and Marxist critics added that poverty and starvation are caused by the unequal distribution of economic resources, not by population growth itself.

03
The Theory of Demographic Transition
The theory of demographic transition links population growth to levels of economic development and says every society passes through a typical pattern. In the first stage, an underdeveloped and technologically backward society has both a very high birth rate and a very high death rate, so net growth is low. The third and last stage is again one of low growth, but in a developed society where both birth rate and death rate have fallen considerably and the gap between them is small. Between these two lies a transitional stage of very high population growth. This 'population explosion' occurs because death rates fall quickly through better disease control, public health and nutrition, while it takes much longer for society to adjust its reproductive behaviour, which had evolved under conditions of poverty and high death rates. Western Europe made this transition in the late nineteenth and early twentieth century. In India the transition is not yet complete: mortality has fallen but the birth rate has not come down to the same extent.
Stage 1high birth rate and high death rate, low growth
Stage 2 (transitional)death rate falls fast, birth rate falls slowly, very high growth
Stage 3low birth rate and low death rate, low growth
Net growth rate = birth rate − death rate

Common Concepts and Indicators in Demography
Most demographic concepts are rates or ratios involving two numbers: the statistic for a particular area and a standard for comparison. The birth rate is the number of live births per 1000 population in a given area during a specified period, usually a year; the death rate is the number of deaths per 1000 population in the same way. The difference between them is the rate of natural increase or growth rate. When this difference is zero or very small, the population is said to have stabilised or reached replacement level, the rate of growth needed for new generations to replace older ones; some societies, such as Japan, Russia, Italy and Eastern Europe, have fertility below replacement level. The fertility rate is the number of live births per 1000 women in the child-bearing age group, usually 15 to 49 years, and is a crude rate because it ignores age differences. The infant mortality rate is the number of deaths of babies before one year of age per 1000 live births, and the maternal mortality rate is the number of women who die in childbirth per 1,00,000 live births. Life expectancy is the estimated number of years an average person is expected to survive. The sex ratio is the number of females per 1000 males. Age structure is the proportion of persons in different age groups, and the dependency ratio compares dependents (below 15 and above 64) with the working-age population (15–64), usually expressed as a percentage.

Size, Growth and Age Structure of India's Population
India is the second most populous country in the world after China, with 121 crores (1.21 billion) people according to the Census of India 2011. Growth was modest between 1901 and 1951, when the average annual growth rate did not exceed 1.33%; between 1911 and 1921 there was even a negative rate of −0.03%, caused by the influenza epidemic of 1918–19, which killed about 12.5 million people, roughly 5% of the population. Growth accelerated after independence, reaching 2.2% during 1961–1981, and has since declined but remains high. Before 1931 both birth and death rates were high; after that transitional moment the death rate fell sharply while the birth rate fell only slightly. India has a very young population. The share of the under-15 age group fell from 42% in 1971 to 29% in 2011, the 15–59 group rose from 53% to 63%, and the 60+ group is small but rising. The bias towards younger age groups is believed to give India a 'demographic dividend', but this benefit is not automatic — it requires education, employment and planned development.

The Declining Sex Ratio in India
The sex ratio is an important indicator of gender balance. Worldwide there are usually slightly more females than males — roughly 1050 females per 1000 males — because girl babies resist disease better in infancy and women tend to outlive men. India, however, has had a declining sex ratio for more than a century: from 972 females per 1000 males in 1901 to 933 in 2001, with a modest rise to 943 in 2011. More alarming is the child sex ratio for the 0–6 age group, which fell from 976 in 1961 to 919 in 2011. In 1991–2001 the overall sex ratio rose by 6 points while the child sex ratio plunged by 18 points, dropping below the overall ratio for the first time. Haryana has the lowest child sex ratio at 793, followed by Punjab, Jammu & Kashmir, Delhi, Chandigarh, Uttarakhand and Himachal Pradesh. Since maternal mortality generally declines with development, social scientists look to the differential treatment of girl babies: severe neglect in infancy, sex-specific abortions and female infanticide. The lowest child sex ratios are found in some of the most prosperous regions, so the problem is not simply one of poverty or ignorance. The Pre-natal Diagnostic Techniques (Regulation and Prevention of Misuse) Act has been in force since 1996 and was strengthened in 2003, and the Beti-Bachao, Beti-Padhao programme aims to improve the child sex ratio.

Literacy and Rural-Urban Differences
Literacy is a prerequisite to education and an instrument of empowerment: it widens awareness of career options, supports participation in the knowledge economy and encourages health awareness. Literacy has improved considerably since independence, and almost two-thirds of the population is now literate, but progress has to keep pace with a still-rapidly growing population. Literacy varies by gender, region and social group. In 2011 the literacy rate was 73.0% overall, 80.9% for males and 64.6% for females, a male-female gap of 16.3 percentage points. Female literacy has been rising faster than male literacy, partly because it started from a low level. Scheduled Castes and Scheduled Tribes have lower literacy rates, and female literacy within these groups is lower still; Kerala approaches universal literacy while Bihar lags far behind. Inequalities in literacy tend to reproduce inequality across generations. On rural-urban differences, the vast majority of Indians still live in villages: in 2011, 68.8% of the population was rural and 31.2% urban. The urban share has risen steadily from about 11% at the beginning of the twentieth century. Agriculture now contributes only about one-sixth of the gross domestic product, and rural people increasingly take up non-farm occupations or travel to nearby towns for work. Cities act as magnets for rural migrants, especially where common property resources like ponds, forests and grazing lands have declined, and the anonymity of city life can offer partial relief from caste-based humiliation in the village.

Population Policy in India
India has had an official population policy for more than half a century and was perhaps the first country to announce one explicitly, in 1952. The policy took concrete form as the National Family Planning Programme, whose broad objective was to influence the rate and pattern of population growth in socially desirable directions. In its early days the emphasis was on slowing population growth through birth control methods, better public health standards and greater public awareness of population and health issues. The programme suffered a setback during the National Emergency of 1975–76, when a coercive mass sterilisation drive was carried out — sterilisation refers to procedures like vasectomy for men and tubectomy for women that prevent conception and childbirth. Poor and powerless people were forcibly sterilised and lower-level government officials were put under pressure to bring people to sterilisation camps. There was widespread popular opposition, and the government elected after the Emergency abandoned the programme. It was renamed the National Family Welfare Programme, coercive methods were dropped, and new guidelines were framed in the National Population Policy of 2000. In 2017 the government brought out the National Health Policy 2017, incorporating many socio-demographic goals with new targets. The lesson of this history is that while the state can create conditions for demographic change, fertility is ultimately a matter of economic, social and cultural change.

Demography is the systematic study of population; formal demography is quantitative, while social demography studies social causes and consequences.
Malthus argued population grows in geometric progression while subsistence grows in arithmetic progression, making famines and diseases inevitable; his predictions were refuted by European experience.
The theory of demographic transition describes three stages, with a 'population explosion' in the middle stage when death rates fall faster than birth rates.
Key indicators include birth rate, death rate, growth rate, fertility rate, infant and maternal mortality rates, life expectancy, sex ratio, age structure and dependency ratio.
India's population was 121 crores (1.21 billion) in 2011; growth accelerated after independence to 2.2% during 1961–1981 and has since slowed.
India has a young population: in 2011, 29% were aged 0–14, 63% were 15–59 and 8% were 60 and above.
India's overall sex ratio fell from 972 in 1901 to 927 in 1991 before rising to 943 in 2011; the child sex ratio fell to 919 in 2011.
Literacy in 2011 was 73.0% overall, with a male-female gap of 16.3 percentage points; Kerala approaches universal literacy while Bihar lags behind.
In 2011, 68.8% of Indians lived in rural areas and 31.2% in urban areas, with the urban share rising steadily.
India announced a population policy in 1952; the coercive sterilisation drive during the Emergency of 1975–76 was abandoned, and the programme became the National Family Welfare Programme.
Demography is the systematic study of population. The word comes from the Greek demos (people) and graphein (describe). It studies changes in population size, patterns of births, deaths and migration, and the structure and composition of the population, such as the proportions of women, men and different age groups.
What is the difference between formal demography and social demography?
Formal demography is largely quantitative and focuses on measuring and analysing the components of population change, using mathematical methods to forecast growth and changes in composition. Social demography, also called population studies, enquires into the wider social, economic and political causes and consequences of population structures and change.
What is the theory of demographic transition?
It suggests that population growth is linked to levels of economic development and that every society follows a typical pattern. Stage one has high birth and death rates and low growth; the transitional stage has a fast-falling death rate and a slowly falling birth rate, producing very high growth; stage three has low birth and death rates and low growth again.
Why is the transition period associated with a population explosion?
During the transition, death rates are brought down relatively quickly through disease control, public health measures and better nutrition. Birth rates, however, are sociocultural and change slowly, because reproductive behaviour evolved under conditions of poverty and high death rates. The widening gap between the two rates produces rapid population growth.
Why is India's sex ratio declining?
Maternal mortality has been declining with development, so it cannot explain the worsening sex ratio. Social scientists point instead to the differential treatment of girl babies: severe neglect in infancy leading to higher death rates, sex-specific abortions, and female infanticide. The lowest child sex ratios occur in some of the most prosperous regions, so poverty and ignorance alone are not the cause.
What is the demographic dividend?
The demographic dividend is the benefit flowing from a changing age structure in which the working-age population is large relative to dependents, lowering the dependency ratio and creating potential for economic growth. It is temporary, because the large pool of workers will eventually become non-working old people, and it requires education and employment to be realised.
