World Population

But are countries that crowded?

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)

World Population Density

But are countries really that crowded everywhere?

Population distribution refers to the pattern of where people live.

World Population Distribution

Dense vs Sparse Population

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.
