8. Population Density
–An average population figure for an area (e.g.
Country). Normally measured per km².

Different reasons cause people to live in different
areas and these can be split into both physical and
human factors.
What factors effect where people live?

FACTOR HIGH DENSITY LOW DENSITY
14. Physical Factors Affecting
Population Density
a. Physical Factors High Density Low Density
1. Relief
(shape and height of
land)
Low land which is flat e.g.
Ganges Valley in India
High land that is
mountainous e.g.
Himalayas
2. Climate Areas with temperate
climates tend to be
densely populated as
there is enough rain and
heat to grow crops e.g.
UK
Areas with extreme
climates of hot and
cold tend to be
sparsely populated e.g.
the Sahara Desert

16. Where would you rather live?
Why do cities grow?
•Political factors
17. Where would you rather live?
•Job opportunities have encouraged city growth
18. Human Factors Affecting
Population Density
b. Human Factors High Density Low Density
1. Political Countries with stable
governments tend to
have a high population
density e.g. Singapore
Unstable countries
tend to have lower
population densities
as people migrate
e.g. Afghanistan.
2. Economic Good job opportunities
encourage high
population densities,
particularly in large
cities in MEDCs and
LEDCs around the
world.
Limited job
opportunities cause
some areas to be
sparsely populated
e.g. Amazon
Rainforest

19. YOUR TURN!• TASK:
1. Look at your A4 sheet and
write down why people live
where they live.
2. Use the ‘interactive climate
map’ on line to help you.
3. Also use the map that you
had at the start of the
lesson to see what the
population density is in the
country
