Population Density is the measure of the
number per unit area. It is commonly
represented as people per square kilometre.
= Total Population / Total Area (km2)

World Population Density
But are countries really that crowded everywhere?
Population distribution refers to the
pattern of where people live.
What factors affect population distribution?
Accessibility eg distance
from sea coast, natural
harbour, navigable rivers
Controls on trade and
Types of economic
technology eg type of
Explain how each of these factors lead to
sparse and dense population density.
