Population density
• What is it?• How does it vary
around the world?• What affects it?

What is it?• Population density = the average number of
people living in a given area
• Population density = Population Per sq km Area (KM)
DENSELY POPULATED e.g.. 243 sq km
China
SPARSELY POPULATED e.g. 2 sq kmAustralia
