How to calculate the population density of an island
The world’s population is expected to grow by over 50 million people by 2050.
However, it’s still not clear how many of these people will live in cities and suburbs.
Arithmetic density is the amount of people in a square kilometre.
A population density in a city is the percentage of people living in a specific area.
For example, a city with a population density around 30 people per square kilometer would have a population of around 1,000,000 people.
In contrast, a population with a density of less than 10 people per sq. kilometre would have only around 50 people living there.
A city with the density of around 20 people per kilometre could also be a major population centre.
