(i)                 Effect of birth and death rate on population size.

(ii)               Composition of population (age group, sex ratios).

(iii)             Change in the distribution of population due to migration, again birth and death.

(i)                 Awareness among students about the consequences of uncontrolled population growth.

(iii)             Relation of population to standard of living.
