REASON OUT WHY

(i) Why is the quality of people more important than quantity of people?

This statement is quite true that quantity of people has got its own value but it is so upto a certain point. Beyond that the excessive number becomes a liability rather than an asset. Then only the quality of the people matters and not the number. Where man is an asset, he is curse as well. As far as our own country is concerned, out population is becoming a great liability on us. We should seriously think of restricting the number of people and the growth of population and should lay stress on improving the quality of the people by providing them balanced and nutritious food, necessary medical care and technical and professional training. The growth of population should also be checked by making the people aware of the small family norms.

(ii) Why has the number of women per thousand of men been steadly decreasing?

The number of women per thousand men is called sex ratio. In 1901 the ratio between the male and female population was 1000 : 972 but it dropped to 1000 : 929 in 1991. However, in the last decade, it has shown a little increase in ratio from 929 females per 1000 males to 933 females per 1000 males in 2001. However, females are lesser than men per 1000.

This lesser female population in India is due to the following causes :

1. Lesser care of female children as compared to male children.

2. Women are subject to greater risks to their lives especially at the time of child birth.

3. Women are also killed or forced to die by the dowry seekers and sometimes poor parents who cannot afford dowry and let their infant daughter die.

4. Due to illiteracy, they cannot avail of the medical facilities.

(iii) Why is dependency ratio higher in India?

The number of dependent persons per hundred on working persons is called the dependency ratio. In India in 1991, the working population was 55.991 % while the dependent population was 44.1%. The dependency ratio is calculated by dividing dependent population by the active population and multiplying by 100. In this way, the dependency ratio in India in 1991 comes to 78 %. This is quite high as compared to Japan whose dependency ratio is 48.8 %. It means the proportion of dependent population in India is quite higher as compared to Japan.

In India, this dependency ratio is quite higher because of the following reasons :

1. Here percentage of children below the age of 15 is quite high. They form 34.33 % of the total population.

2. Here old men, forming 6.97 % of the total population, also form a part of the dependency population.

The dependency ratio in India can be reduced by lowering the birth rate over a couple of decades so that not much pressure is put on the economically active population and on our limited resources including health and medical care.

(iv) Why West Bengal is more densely populated than Punjab? West Bengal is more densely populated than Punjab. While in Punjab, the density of population is 403 persons
per sq. km that of West Bengal is 767 persons per sq. km. The reasons for the same are the following:

1. While in Punjab, the growth rate declined between 1981 to 1991, in Bengal, however, it increased, thus adding to the density of population in case of Bengal.

2. There is more migration of people from Punjab to other countries as compared to Bengal.

3. The continuous illegal entry of Bangladesh is into West Bengal added to the density of population in Bengal while there is very little entry of people from Pakistan into Punjab.

(v) Why Kerala state is densely populated?

Kerala state is densely populated. Some of the reasons for the same are the following :

1. Kerala state is a part of the West Coastal Plains which are quite levelled and fertile and there is enough of rainfall. As such, there is no scarcity of food in Kerala.

2. Kerala lies on the sea-shore for a long distance as such she earns both in external and internal trade.

(vi) Why is West Bengal the most thickly populated state in India?

Of all the states of India. West Bengal has the highest density of population with 904 persons per sq. km (Census 2001). The reasons for the same are the following :

1. West Bengal receives a fair amount of rainfall. The Ganga river also provides large irrigational facilities.

2. This region is flat and has very fertile alluvial soils which produce in abundance to eat.

3. West Bengal is centre of many agro-based and metal-based industries which provide work to large number of people.

COMPARATIVE STUDY

(i) Difference between the Birth Rate and the Death Rate :

The difference between the birth rate and the death rate gives us the growth rate of population of any country in a year. It must be remembered that one main cause of higher growth rate in India is the widening gap between the birth rate and the death rate. No doubt, the birth rate which was 49.2 per thousand in the beginning of the 20th century has come down to 26.1 per thousand at the end of the century. But the death rate declined from 42.6 per thousand to 8.7 per thousand in the same period. It means the birth rate fell at a slower speed than the death rate, hence the increase in the growth rate which is exerting a great pressure on the already depleting resources of India.

(ii) Distinction between the productive population and dependent population

That part of the population which is engaged in productive activities for earning is called the productive population. These people usually fall in the age group of 15-59. By and large women are not engaged in economically productive activities. The percentage of working population in India is 59.7 % (as.in 2001). That part of the population, which is not engaged in any productive activity and is dependent on the working population, is called the dependent population. This part of population includes children below 15 i.e. age group 0-14 and adults of 60 years and above. They comprise 41.3 % of the total population. This percentage is quite high.

(iii) Distinction between population growth and population change :

Population Growth : Population growth is the actual addition in the existing population during a particular period, say a year. It is the difference between the births and deaths during that period., India's current annual increase in population is 1.5 crore which is increasing our population year after year. Population Change : Population change is the result of three main factors of components birth rate, death rate and migration. The population change is the result of difference between the births and deaths in a year plus the migration from one part of the country to the other or from one country to the other.
