# POPULATION DENSITY

POPULATION DENSITY

Population density is defined as the number of persons per square kilometre of land.

The population density of a country can be expressed mathematically as:

## Example of population density

Calculate the population density of Nigeria, having a total population of 88,514,501 as of 1991 with a total land area of923,768 sqkm. Solution

Total population =        88,514,501

Total land area =           923,768 km2

Population density =     Total population

Total land area =      88.514.501

923,768

95.8

=      96 persons /km2

Population density may either be high or low depending on the number of people in a specified area or country. Generally, high population density occurs where there are many people in an area which leads to over population as discussed earlier.

Similarly, a low population density refers to a situation where there are few people in a specified area of land.
