Which term describes how many people live in a certain area (e.g., per square kilometer)?

• A. Population
• B. Population Density
• C. High Population
• D. Constrictive

Answer: (B)

Population density describes how many people live in a given area, typically measured as the number of people per square kilometer. It’s found by dividing the total population by the land area, so it shows how crowded a place is and helps planners decide where houses, roads, and services are needed. The total population, while important, doesn’t account for how large the area is, so it doesn’t convey crowding per unit area. High Population isn’t a standard term for this idea, and constrictive isn’t related to measuring how many people live in an area.
