A population pyramid with a very wide base that narrows sharply in older age groups is observed in a developing country. This shape is best described as which type of pyramid?
- A Constrictive
- B Stationary
- C Expansive ✓
- D Constricted
Correct answer: C. Expansive
Explanation
An expansive population pyramid has a wide base and narrow top, indicating high birth rates and high death rates, typical of developing countries with young, growing populations. A constrictive pyramid has a narrow base, seen in aging populations. A stationary pyramid has roughly equal proportions across age groups, indicating stable population growth.
