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

18. What factors affect population distribution?
Physical Human
Climate
Landforms
Topography
Soil
Energy
Mineral resources
Accessibility eg distance
from sea coast, natural
harbour, navigable rivers
or canals
Political boundaries
Controls on trade and
migration
Government policies
Types of economic
activities
technology eg type of
farming, transportation
facilities, social
organisation, demographic
factors
Explain how each of these factors lead to
sparse and dense population density.
