(ii) The major components of population growth are natural increase of population and immigration. Natural increase of a population is the difference between the birth rates and the death rates in that populations. Immigration refers to the inflow of people into a region from other regions.

Death rate is the number of deaths per thousand persons in a year.

Birth rate is the number of live births per thousand persons in a year.
