Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

What is population density?

Back

Population density is the average number of people living per unit area, usually expressed as people per square kilometer or square mile.

Front

How do you calculate population density?

Back

Population Density = Total Population / Total Area.
