A population pyramid with a wide base and rapidly narrowing upper sections indicates which of the following?
- A Low birth rate and low death rate with an aging population
- B Population decline due to emigration
- C High birth rate and high death rate with a young population ✓
- D Constrictive population structure with low fertility
Correct answer: C. High birth rate and high death rate with a young population
Explanation
A wide base indicates a high proportion of young people, reflecting high birth rates. The rapid narrowing indicates high death rates in older age groups. This is the classic expansive pyramid seen in developing countries. Option A describes a stationary pyramid. Option D describes a constrictive pyramid. Option B is not a standard pyramid type.
