Decreased population due to a reduced death rate and an increased fertility rate

Explanation:
Detailed explanation-1: -Population momentum explains why a population will continue to grow even if the fertility rate declines. Population momentum occurs because it is not only the number of children per woman that determine population growth but also the number of women of reproductive age.
Detailed explanation-2: -As fertility declines, the proportion of children in the population falls and the proportion of the population of working age increases, resulting in a lower dependency ratio (defined as the number of children and older persons per 100 persons of working age).
