What is population management? How do birth spacing and proper age at marriage help in controlling rapid population growth?

Population management refers to the proper distribution of the population according to the availability of means and resources in a certain area. The gap between first child and second child or two consecutive births is known as birth spacing. It is an interval of time after a bit of a baby to the next. If the birth spacing is following a long period, It is good for both mother and child and it also helps to control the population. The gap between two children should be at least four to five years to achieve sound health for the mother and children. That's why birth spacing is one of the best measures of population control.

This is often understood as appropriate age at marriage. It denotes the marriage after becoming physically, socially, mentally, and economically capable to bear a child. The suitable age of marriage for girls and boys are 20 years and 25 years respectively from a reproductive point of view. Appropriate age at marriage reduces the total fertile life span of females. The delayed marriage reduces the fertility period of women and controls the population. The age of 15 to 49 is regarded as the fertility period. If a woman marries at the age of 15, the total length of the fertile period becomes 34 years. If she marries after 15 years, her fertility period becomes shorter than 34 years which directly helps to control the population.
