Answer:
factor affecting distribution of population as below
1) Water Bodies:
Availability of water plays a significant role in determining the population of a given area. Water is the basic necessity for several purposes including irrigation, industries, transport and domestic affairs. Rivers are the greatest source of fresh potable water. Therefore, most of the population is concentrated in the river valleys.
2) Industries:
Industrial growth offers massive employment opportunities and acts as a great magnet to attract people, particularly from the neighbouring areas. This results in higher population density. Industrial areas are almost invariably associated with areas of high population densities.
3)Urbanization:
Urbanization and population concentration go hand-in-hand and are closely related to each other. All the urban centres are marked by high density of population. The minimum density, that an area should have to be designated as urban, is 400 persons per sq km. The highly urbanized districts of Kolkata, Chennai, Greater Mumbai, Hyderabad, Delhi and Chandigarh have population densities of over 6,000 persons per sq km.
4)Climate:
Climate is as important as terrain in influencing population. Of all the climatic factors, twin elements of rainfall and temperature play the most important role in determining the population of an area. Man cannot go beyond the limits set by climate.
5)Mineral Resources:
Minerals act as great source of attraction for people from different areas, which results in higher density of population. The higher population densities in the Chhota Nagpur Plateau of Jharkhand and in the adjoining areas of Orissa are largely due to the availability of minerals.
6.Terrain:
Terrain of land is a potent factor which influences the concentration and growth of population. Normally speaking, plain areas encourage higher density of population as compared to mountain regions. The steep slope in mountain areas restrict the availability of land for agriculture, development of transport, industries and other economic activities which may tend to discourage concentration of population and its proper growth.
It is because of these adverse circumstances that the Himalayan region, though occupies about 13 per cent of India’s land area, supports only 1-2 per cent of the country’s population. In contrast to this, the Great Plain of North India is a land of extremely gentle slope and offers great opportunities for the growth of agriculture, transport and industries.
This results in higher concentration of population. Although the Great Plain of North India covers less than one fourth of the country’s land area, it is the home to more than half of India’s population.
7.Climate:
Climate is as important as terrain in influencing population. Of all the climatic factors, twin elements of rainfall and temperature play the most important role in determining the population of an area. Man cannot go beyond the limits set by climate.
Extremes of climate discourage the concentration of population. Such climates include the too cold climate of Himalayas, and the too hot and dry climate of the Thar Desert. A moderate climate, on the other hand, is favourable for population.
Of the twin factors of rainfall and temperature, rainfall is more effective in determining the distribution of population. It is generally said that the population map of India follows its rainfall map. Rainfall supplies sufficient water for agriculture which is the main occupation of Indian masses.
As we move from the Ganga-Brahmaputra Delta in the east towards the Thar Desert in the west, the amount of rainfall and consequently the density of population decrease. However, there are a few exceptions to this general observation.
The Assam valley in the north-east and the Circars coast on the Bay of Bengal has moderate density of population although these areas receive heavy rainfall. Similarly, southern face of the Himalayas is scarcely populated though this area receives sufficiently high rainfall.
Some of the adverse factors such as steep slope, frequent floods, infertile soils and dense forests counterbalance the positive effect of rainfall. Increased use of irrigation facilities in north-west India comprising Punjab, Haryana and western Uttar Pradesh has resulted in higher concentration of population than normally expected considering the amount of rainfall received by this region.
Since India is a tropical country, temperature is fairly high and does not play as important a role as is done by rainfall except in extreme cases. On high altitudes, in the Himalayan region, climate is too cold beyond 2,000 m and population is sparse there. There is practically no population in areas over 3,000 m above sea level.
