Question

what is the reason that many african countries are said to have population momentum? many african countries have not yet reached replacement fertility rates. many african countries have younger workers who have difficulty starting careers. many african countries have a high number of young women who have not yet given birth. many african countries have retirees who live longer and use more social benefits.

Explanation:

Population momentum occurs when a large proportion of a population is in the child - bearing age group. In many African countries, there is a high number of young women who have not yet given birth, which means there is potential for continued population growth even if fertility rates start to decline. Replacement fertility rates are not the main cause of population momentum here. Difficulty of young workers starting careers and retirees using social benefits are not related to population momentum.

Answer:

Many African countries have a high number of young women who have not yet given birth.
