A Study On India's Population

a. Size of the population compared to the world population

The world has a population of 6 billion. India alone has a population of 1 billion approximately. India accounts for 16% of the world's population approximately.

b. India 's geographic area compared to the world geographic area? What percentage is India 's geographic area and density of population?

By area, India is the seventh largest country in the world. It consists of twenty-eight states and seven Union Territories. Area covered by India is 3.3 million sq. kms approximately. World geographic area is 1.48 billion sq. kms approximately. India's density of population is approximately 336 persons per square km whereas world's density of population is 44.57 persons per sq.km

b. The demographic transitions- 3 stages and which stage India is in

Demographic transition occurs in societies that transition from high birth rates and high death rates to low birth rates and low death rates due to the economy of the country.

Stage One

In pre-industrial society, death rates and birth rates were both high and fluctuated rapidly according to natural events, such as drought and disease, to produce a relatively constant and young population.

Stage Two

This stage leads to a fall in death rates and an increase in population. The changes leading to this stage in Europe were initiated in the Agricultural Revolution of the 18th century and were initially quite slow. In the 20th century, the falls in death rates in developing countries tended to be substantially faster. Countries in this stage include Yemen, Afghanistan, Palestine, Bhutan and Laos and much of Sub-Saharan Africa (but do not include South Africa, Zimbabwe, Botswana, Swaziland, Lesotho, Namibia, Kenya and Ghana, which have begun to move into stage 3).

A consequence of the decline in mortality in Stage Two is an increasingly rapid rise in population growth (a "population explosion") as the gap between deaths and births grows wider. Note that this growth is not due to an increase in fertility (or birth rates) but to a decline in deaths. This change in population occurred in northwestern Europe during the 19th century due to the Industrial Revolution. During the second half of the 20th century less-developed countries entered Stage Two, creating the worldwide population explosion that has demographers concerned today.

The decline in death rates in Stage Two entails the increasing survival of children and a growing population. Hence, the age structure of the population becomes increasingly youthful and more of these children enter the reproductive cycle of their lives while maintaining the high fertility rates of their parents. The bottom of the "age pyramid" widens first, accelerating population growth. The age structure of such a population is illustrated by using an example from the Third World today.

Stage Three

Stage Three moves the population towards stability through a decline in the birth rate.

A major factor in reducing birth rates in stage 3 countries such as Malaysia is the availability of family planning facilities, like the one in Kuala Terenganu, Terenganu, Malaysia.

The resulting changes in the age structure of the population include a reduction in the youth dependency ratio and eventually population aging. The population structure becomes less triangular and more like an elongated balloon. During the period between the decline in youth dependency and rise in old age dependency there is a demographic window of opportunity that can potentially produce economic growth through an increase in the ratio of working age to dependent population; the demographic dividend.

However, unless factors such as those listed above are allowed to work, a society's birth rates may not drop to a low level in due time, which means that the society cannot proceed to Stage Four and is locked in what is called a demographic trap.

Countries that have experienced a fertility decline of over 40% from their pre-transition levels include: Costa Rica, El Salvador, Panama, Jamaica, Mexico, Colombia, Ecuador, Guyana, Surinam, Philippines, Indonesia, Malaysia, Sri Lanka, Turkey, Azerbaijan, Turkmenistan, Uzbekistan, Egypt, Tunisia, Algeria, Morocco, Lebanon, South Africa, India and many Pacific islands.

Countries that have experienced a fertility decline of 25-40% include: Honduras, Guatemala, Nicaragua, Paraguay, Bolivia, Vietnam, Myanmar, India, Bangladesh, Tajikistan, Iran, Jordan, Qatar, United Arab Emirates, Zimbabwe and Botswana.

Countries that have experienced a fertility decline of 10-25% include: Haiti, Papua New Guinea, Nepal, Pakistan, Syria, Iraq, Saudi Arabia, Libya, Sudan, Botswana, Kenya, Ghana and Senegal.

India is currently in Stage 3 of the demographic transition stages.

C. what is the optimum population based on the Malthusian theory of population

Thomas Robert Malthus made the famous prediction that population would outrun food supply, leading to a decrease in food per person.

According to Malthus, "The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race. The vices of mankind are active and able ministers of depopulation. They are the precursors in the great army of destruction, and often finish the dreadful work themselves. But should they fail in this war of extermination, sickly seasons, epidemics, pestilence, and plague advance in terrific array, and sweep off their thousands and tens of thousands. Should success be still incomplete, gigantic inevitable famine stalks in the rear, and with one mighty blow levels the population with the food of the world."

d. Effects of the increasing population on the economic, public and social aspects of the country

Ð'* High infant and child mortality. High rates of infant mortality are caused by poverty.

Ð'* Starvation, malnutrition, poor diet with ill health and diet-deficiency diseases (e.g. rickets).
