1.	Describe the basic factors affecting the population of India.
Answer» The basic factors affecting the population of India are: (i) Birth rate- It is the number of births per 1000 individuals of a country’s population per annum. It increases both population size and population density. (ii) Death rate- It is expressed as the number of deaths per 1000 individuals of a nation’s population per year. It decreases both population size and density. (iii) Immigration- It is the entry of more individuals into a local population of a species in a specific area from outside due to more favourable conditions in that area. (iv) Emigration- It is the departure of some individuals from a local population to another area due to unfavourable conditions in the former. It decreases population size of that area.

The basic factors affecting the population of India are:

(i) Birth rate- It is the number of births per 1000 individuals of a country’s population per annum. It increases both population size and population density.

(ii) Death rate- It is expressed as the number of deaths per 1000 individuals of a nation’s population per year. It decreases both population size and density.

(iii) Immigration- It is the entry of more individuals into a local population of a species in a specific area from outside due to more favourable conditions in that area.

(iv) Emigration- It is the departure of some individuals from a local population to another area due to unfavourable conditions in the former. It decreases population size of that area.
