Question

What demographic group expansion is identified as a cause of population explosion?

Options

• Increased number of children under 5 years

• Increased number of people in the reproductive age group

• Increased number of elderly persons

• Increased number of disabled individuals

Answer 1

An increased number of people in the reproductive age group is identified as a cause of population explosion. As death rates decline, particularly among infants and children, more individuals survive to reproductive age. This creates a large cohort of fertile individuals capable of bearing children, amplifying population growth even if individual family sizes decrease. This demographic effect, known as population momentum, ensures continued rapid growth even with declining fertility rates, as more women of childbearing age enter their reproductive years.
