Question

Consider five human populations that differ demographically only in their age structures. The population that will grow the most in the next 30 years is the one with the greatest fraction of people in which of the following age group?

Options

• 10-20

• 20-30

• 30-40

• 40-50

Answer 1

10-20

Explanation:

The population that will grow the most in the next 30 years is the one with the largest fraction of people in the age group 10-20 years. This is because a broad base in the age pyramid, representing a high percentage of young individuals in the pre-reproductive age group, leads to rapid population growth as this group enters reproductive age and contributes to the birth rate.
