Consider the four age pyramids given below namely A, B, C and D representing four different countries. Which one of them indicates the declining population?
- A.A
- B.B
- C.C
- D.D
▶ Answer & Explanation
Correct answer: D. D
A declining population is typically characterized by a pyramid shape that is narrower at the base and wider in the middle age groups, indicating fewer young people and a larger proportion of older individuals. This results in a lower birth rate and a higher death rate over time, leading to a contraction of the population size.
