Question

What does the shape of the given age pyramids (A to C) reflect about the growth status of populations?

A B C

• A. Declining Stable Expanding
• B. Stable Expanding Declining
• C. Expanding Stable Declining
• D. Declining Expanding stable

Answer 1

The correct option is C Expanding Stable Declining

Triangular age pyramid has high proportion of preoperative
individuals, moderate number of reproductive individuals and fewer post-reproductive individuals. It represents young or rapidly growing population.
In urn-shaped age pyramid, the number of reproductive individuals is higher than the number of pre-reproductive individuals. It represents declining or diminishing population with negative growth.
In bell-shaped age pyramid, the number of pre-reproductive and reproductive individuals is almost equal. Post reproductive individuals are comparatively fewer. It represents stable or stationary population, neither growing nor diminishing.
