The Demographic Structure of the Indian Society
Notes
Demography – the systematic study of the population of a country, area, community, etc. The term is of Greek origin and is composed of the two words, demos (people) and graphein (describe). |
There are two types of demography –
|
1. Formal Demography – statistical analysis of population i.e., total population, number of males, number of females, number of youth, working population, rural urban (quantitative data) |
2. Social Demography – birth rate, death rate and migration that happens in a particular society. Consists of four processes –
|
The Malthusian Theories of Population Growth • Malthusian Theory was propounded by Thomas Robert Malthus. • According to him there are two important things that matter. (i) Population – People • According to him population can grow uncontrollably. It grows in ‘geometric progression’ (2, 4, 8,16, 32, 64 …). It is fast. • Land gives limited return. It grows in arithmetic progression (2,4,6,8,10 ). It is slow. • Population is growing uncontrollably, land is not able to sustain the large population which leads to poverty, hunger, saturation etc. • Malthus came up with 2 solutions. Positive check – Natural disasters cause many people die and the population is naturally controlled. If one doesn’t take care of themselves nature will take care of them e.g. earthquakes, tsunami. Preventive check – Man made e.g. late marriage, celibacy, contraceptives etc. |
Criticism of Malthusian Theory According to sociologists, poverty, hunger etc is not due to less agricultural growth but due to unequal economic resources. Agricultural production is not limited due to the advancement of science and technology. Along with population growth, there is an increase in the standard of living. This is because of science and technology. |
Theory of Demographic Transition – Population is moving from underdeveloped to developed countries. |
There are three stages – 1. Primitive Stage-underdeveloped countries (Africa). |
Underdeveloped Countries (stage 1) • Birth rate is high since people are unaware of the advantages of having small families, they are not educated. |
Developing Countries (stage 2) • Birth rate is high as we live in a patriarchal society where men decide how many children – must be bom and male child is preferred. |
Developed Countries (stage 3) • Birth rate is low, people are educated and aware and use contraceptives, birth control is popularised. |
Population Explosion – When the birth rate of a country is high and the death rate is low because of availability of health and medical facilities. Therefore population is exploding, increasing. |
Common Concepts of Population 1. Birth Rate – Number of live births per thousand population.
4. Fertility Rate – Number of live births between the age of 15-49 yrs per thousand women. |
Size and Growth of India’s Population – Today the population of India is very high but it has not always been high. Growth has been up and down. |
Causes
|
Epidemics – Disease which is widespread and affects lakhs of people in a large area. For example, during the World War there spread the Spanish influenza. It affects the throat and cavity and you choke and die. It is believed to have killed more people than any war. It spreads very fast and is contagious because:
They are less common now because
In India we still have some epidemics like swine flu, chickenguniya, plague, malaria etc. |
Famine – There is scarcity of food, shortage of food supply and production. It is of two types
Dr. Amartya Sen, “It is not necessary that famine is due to lack of food grain but it could be due to lack of efficient distribution, failure of entitlements and inability of people to buy or otherwise obtain food.” Efficient distribution of foodgrains by improving transportation and community, (it) Green Revolution has increased the supply of foodgrains despite varying amounts of rainfall. 3. Medical facilities – If an area is experiencing famine, the government takes caution/ measures to see that the people are given help. |
NREGA-National Rural Employment Guarantee Act – Takes care to see that everyone is employed so that if there is a famine they can move somewhere else and buy food. Total Fertility Rate When the birth rate is high and death rate is low it results in population explosion. In a country birth rate is still high because of (i) Mindset of people |
Replacement Level
|
Low Fertility Rate – Tamil Nadu, Karnataka, Himachal Pradesh, West Bengal, Kerala, Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh (Mostly northern states due to desire for male child). Age Structure of Indian Population.
Demographic Dividend – Working population is higher than the non-working population. Kerala – Good age structure ➙ increase in working population, the literacy rate is very high, so they are educated about economic growth. Uttar Pradesh – Increase in working population because of large working youth population, decreasing aged population.
|
The Declining Sex Ratio in India
Reasons for declining sex ratio – (i) Mindset of the people • The child sex ratio is still very scary as there is a drastic fall. • Prosperous states such as Punjab and Haryana have maximum female infanticide and down with burning because
|
Sonography – to know the sex of the child. • The Pre Natal Diagnostic Technique Act/Regulation and Prevention of Misuse Act which came up in 1996 and was later enforced in 2003. • This does not allow the sex of the child to be known. |
Literacy
There are three categories – (i) Gender – more males are literate to females but it is becoming higher. (ii) Social Group – higher income families have more literacy level than those with lower income families. Govt is trying to bridge the gap through reservation for SC’s and ST’s. (iii) Regions – Kerala has high literacy level as compared to Rajasthan, Bihar which have low literacy level. |
Rural-Urban Differences
|
Reasons for migration from rural to urban areas –
|
Metropolis – City with infrastructure and the suburbs are different. |
Megapolis – City with infrastructure and the suburbs are included, for example, NCR. |
Population Policy of India • In 1952 the National Family Planning Programme (NFPP) was introduced. Its objectives were –
During emergency by Indira Gandhi (1975-76)
|
Words That Matter
1. Age Structure – The proportion of persons of population in different age groups related to the total population. It includes all age groups like children, youth and old people. |
2. Agricultural density – Ratio between people and arable land. |
3. Arithmetic density – Ratio between people and land. |
4. Birth Rate – Number of live births per 1000 population for a given time period and for a particular place. |
5. Census – Official examination of population alongwith certain economic and social statistics in given territory and carried out or a specific way. It bears decodal frequency. |
6. Death Rate – Number of deaths per 1000 population for a given time period and for a particular place. |
7. Density of population – Number of people occupying a certain area and their ratio in any country, region or state viz. Number of people living on one square kilometre of land. |
8. Dependency Ratio – Number of dependent population over working population. |
9. Economic Density – Ratio between people and the availability of economic resources of any region, state or country. |
10. Fertility Rate – Refers to the number of live births per 1000 women in the child bearing age groups usually taken to be 15-49 years. |
11. Infant Mortality Rate – Number of deaths of babies before the age of one year per thousand live births. |
12. Life expectancy – Refers to the estimated number of years that an average person is expected to survive. |
13. Literate – From the point of view of census the person who can read and write any language is a literate. |
14. Maternal Mortality Ratem – Number of women who die in child birth per 1000 live births. |
15. Negative Growth Rate – This happens when fertility levels are below replacement level such as Japan, Russia, Italy. |
16. Rate of Natural Increase or Growth Rate of population – This refers to the difference between the birth rate and death rate. |
17. Replacement Level – When the difference is zero then we say that the population has stabilised or has reached the ‘replacement level’, which is the rate of growth required for new generations to replace the older ones that are dying out. |
18. Sex Ratio – Number of women per 1000 of men population. |
19. Total Fertility Rate – Number of children born upto child bearing years of a women. |
