Question

In a human population, the population momentum effect is most likely to occur in cases in which a large percentage of people in the population are in which age group?

a. Between 30 and 44 years old
b. Younger than 18
c. Between 55 and 65

Answer 1

b. Younger than 18

Step-by-step explanation:

Population momentum is the population growth at the national level that continues even after childbearing levels immediately declined to replacement level. This effect is possible because there are still young people in the population who just reached child bearing age and are now reproducing at their replacement level, leading to a momentum.

The effect is more pronounce in a population with large percentage of individuals younger than 18, this is because they will soon reach child bearing age and start reproducing thereby increasing the momentum.
