Answer:

Components of population change in the world are:

(i) Higher birth rate

(ii) Lower death rate

(iii) Migration.

Impact:

(i) In developing countries like India the levels of maternal and infant mortality are very high. Repeated childbirths are seen as an insurance against multiple infant and child deaths. Vast numbers of people cannot avail of the services provided by government sponsored family planning programmes even when they are available, due to problems of knowledge and its access.

(ii) As the population grows, the pressure on natural resources will increase.

(iii) Population pressure will reduce the per capita availability of land for farming, which will affect availability of food grain, drinking water etc.

(iv) Pressure on basic amenities also increases due to change in population.
