AIIMS 2019 Botany Age Pyramids MCQ Question
Select the correct option w.r.t. Age pyramids.
a - Expanding, b - stable, c - Declining
a - stable, b - Expanding, c - Declining
a - stable, b - Declining, c - Expanding
Correct Answer
Detailed Explanation
Option A is correct because it accurately describes the characteristics of age pyramids: an expanding pyramid (a) indicates a high birth rate and a youthful population, a stable pyramid (b) reflects a balanced birth and death rate with a relatively even distribution across age groups, and a declining pyramid (c) shows a low birth rate and an aging population. Other options are incorrect as they misclassify the types of age pyramids; for instance, option B incorrectly labels a stable population as expanding, which contradicts the demographic transition model. Understanding these classifications is essential for analyzing population dynamics and predicting future demographic trends.
