Population density indicator – UGC NET Question

Population density expresses how many people live in a given unit of land area, allowing comparison of how crowded or sparsely populated different regions are.

Option A:
Incorrect, because the share of people in urban areas describes the level of urbanisation, not density itself.

Option B:
Correct, as it defines density directly as people per unit area of land.

Option C:
Incorrect; the rate of natural increase is based on birth and death rates and shows how fast a population is growing, not how it is distributed in space.

Option D:
Incorrect; the average number of children per woman refers to fertility, not density.
