Topic: Population density

Previous-year question practice database

Answer

Exam answer

POPULATION DENSITY is the number of PEOPLE living per UNIT AREA (usually per square kilometre) at a given time.

Explanation

Both elements must appear: the number of PEOPLE and the UNIT AREA. An answer saying only "the number of people in a place" omits the area and earns half.

DO NOT CONFUSE it with the other population terms, which are all RATES rather than densities: NATALITY — births per 1,000 people per YEAR MORTALITY — deaths per 1,000 people per YEAR GROWTH RATE — natality minus mortality

The UNIT tells you which term is meant: density is per AREA, the rest are per THOUSAND PEOPLE PER YEAR.

Example

Population density = Total population ÷ Total land area (km²)

Example: 5,00,000 people living in 2,000 km² gives a density of 250 persons per km².
