Question

Which one of the following is incorrectly matched ?

List-I (Term)	List-II (Meaning)
(A) Physiological density	Total population/Net cultivated area
(B) Agricultural density	Total agricultural population/Net cultivable area
(C) Population density	Total population/Total area
(D) Marginal worker	Total population/Total working population

• A. A
• B. B
• C. C
• D. D

Hint:

When learning about demographic terms, ensure you understand the specific definitions of terms like physiological density and agricultural density, which are closely tied to the land area, not just population size.

Answer 1

The Correct Option is D

- Option (A) is correct: Physiological density is defined as the total population divided by the net cultivated area, which is accurate.
- Option (B) is correct: Agricultural density refers to the total agricultural population divided by the net cultivable area, which is correctly matched.
- Option (C) is correct: Population density is defined as the total population divided by the total area, which is also correct.
- Option (D) is incorrect: The term "marginal worker" refers to those individuals who are engaged in low-wage or part-time work. It is not calculated by dividing the total population by the total working population. The correct definition of marginal worker is individuals who are not fully employed or engaged in agricultural work on a regular basis. This term is not about calculating a ratio of population and working population.
Thus, the incorrect match is (D).
