1. Population Density
People concentrated into certain parts make them crowded. Crowded areas have a high population density. Other areas have relatively few people living there and these are said to be sparsely populated e.g. the Sahara Desert in north Africa. These areas are said to have a low population density.

8. Factors Influencing Population Distribution and Density
Active volcanoes, mountains, high plateau, low temps and pressures e.g.
Himalayas
Flat lowland plains e.g. N European Plain
Physical Landscape

9. Factors Influencing Population Distribution and Density
Evenly distributed rainfall, no temperature extremes, lengthy growing season
Drought, high humidity, low temperatures. Short growing season
Climate

10. Factors Influencing Population Distribution and Density
Sparse deserts, dense coniferous and rainforests e.g. Amazon
Grassland e.g. plains in the USA
Vegetation

11. Factors Influencing Population Distribution and Density
Deep humus filled or volcanic soils. Fertile river deposited alluvium or silt
Infertile soils, leached, erosion, mountainous
e.g. Tundra
Soils

12. Factors Influencing Population Distribution and Density
Unreliable or lack of rainfall, supply of clean water and technology
e.g. Sahara Desert
reliable- either rainfall or technology to provide reservoirs e.g. Europe
Water Supply

13. Factors Influencing Population Distribution and Density
Few natural hazards, money/medical expertise to eradicate initial hazards UK
Malaria in Central Africa
Disease and pests

14. Factors Influencing Population Distribution and Density
Areas devoid of minerals or easily obtainable energy sources
Large mineral deposits or energy supplies (Ruhr, N. Germany)
resources

15. Factors Influencing Population Distribution and Density
Areas difficult to construct or maintain transport systems e.g. Afghanistan
Natural ports, easy to construct transport links e.g. Norway
communications

16. Factors Influencing Population Distribution and Density
Areas with less developed subsistence economies e.g. tundra, rainforests, desert fringes
Intensive farming due to higher technology result in larger profit e.g. Japan
economic

17. Factors Influencing Population Distribution and Density
Funding to create new towns (Brasilia) or opening ‘pioneer’ lands- government
Areas lacking in state funding where development is not encouraged
