"90 per cent of the world population lives in about 10 per cent of its total land area, whereas the remaining 10 per cent population resides in the 90 per cent of its land area." Support the statement with suitable examples.

Yes, the statement is valid because most people favour living in a location where there is the availability of favourable conditions for life. The factors affecting the population decide the density of the population.

Factors affecting population distribution plays a major role in the settlement of 90% of the population in the world.

• Landforms:

People prefer living on flat plains and gentle slopes. This is because such areas are favourable for the production of crops and to build roads and industries. The mountainous and hilly areas hinder the development of the transport network and hence initially do not favour agricultural and industrial development.

• Availability of water

Water is the most precious natural resource which is very essential for sustenance of life. Therefore people prefer to live in areas where fresh water is easily available.

• Climate

Extreme climates such as very hot or cold deserts are scratchy for human habitation. Areas with a comfortable climate, where there is not much seasonal difference to attract more people. Regions with very heavy rainfall or extreme and unsympathetic climates have low population

• Urbanization

Lack of employment in rural areas is the main reason for the movement of people from rural to urban occurs. In urban areas, there will be more employment opportunities due to factories and industries. Employment status of the society can be improved by the Urbanization.

These factors are responsible for 90% of the population living in 10% of the land area. Where there are exceptions to these factors that contribute the remaining 10% of the population living in 90% of areas and most of them will be tribes and nomadic herders.
