Question

Assertion: In population pyramid, a broad base indicates high number of children in a country.
Reason: Broad apex is an indicator of high number of elderly in a country.

• A. Only Assertion is correct.
• B. Only Reason is correct.
• C. Both Assertion and Reason correct and Reason is correct explanation of Assertion.
• D. Both Assertion and Reason correct but Reason is not the correct explanation of Assertion.

Hint:

Population pyramids reveal age-sex distribution; a broad base signals high fertility, while a broad apex indicates longevity.

Answer 1

The Correct Option is D

Step 1: The assertion is correct: A broad base in a population pyramid indicates a high birth rate, resulting in a high number of children.
Step 2: The reason is correct: A broad apex indicates a high number of elderly, reflecting low mortality rates or longer life expectancy.
However, the reason does not explain the assertion, as the broad base (children) and broad apex (elderly) are independent features of a population pyramid, driven by different demographic factors (birth rate vs.
life expectancy).
