Therefore these areas have a high population. While the areas that lack all these features have a low population.

2. Explain the factors affecting the density of population?

Ans: The factors affecting the density of population are: 

    i. Relief of land plays a dominant role to influence the population distribution. Plains attract population while mountainous areas, bad lands, rugged lands repel population.

    ii. Climate is another important factor. Only areas with favorable climate attract settlement.

    iii. Fertility of soil attracts people. Fertile soils are the support base for agriculture.

    iv. Development of industries is another factor. Industries provide jobs and hence attract people, thus increasing density of population.

    v. Religious places, development of education, medical facilities and development of mining are some other factors which control population distribution.

3. What is the impact of population growth on the economic development of a country?

Ans: The impact of population growth on the economic development of a country are:

    i. High growth rate of population affects the food supply.

    ii. High growth rate gives rise to housing problems also.

    iii. Water supply also becomes a problem when the growth rate is high.

    iv. High growth of population leads to problems of schooling for children, problem of medicine, unemployment and social crimes.

    v. Population growth leads to the destruction of forests and other resources which causes environmental degradation.
