5. www.maps.com/ref_map.aspx?pid =12880 75% people live within 1000 km of sea 85% live in areas less than 500m high 85% live between latitudes 68 o North and 20 o North <10% live in S. hemisphere

6. There are over 6 billion people in the world today. Distribution is very uneven – there are a number of different reasons for this (more on these reasons later!) Asia and Europe have the highest densities of population. World’s population varies latitudinally – 80% lives between 20 and 60 degrees north of the equator. Primary concentrations >100 per sq km - SE Asia, Europe + NE USA. Secondary concentrations 25-100 per sq km – California, coastal Brazil, Nile Valley. Areas of low population density 2-25 per sq km – Norway, New Zealand, Canada, North Africa, S Argentina, Australia. 64% of the world’s land area has <2 people per sq km. 35-40 of this land area is regarded as unihabitable. Areas with environmental advantages tend to be densely populated while those with disadvantages tend to be sparsely populated with social and economic deficiencies. There are exceptions to this - eg Bangladesh.

9. Key to explaining distribution is the ability to feed a population. The world’s 6 billion people are not distributed evenly across the Earth’s surface. Almost all of the world’s inhabitants live on 10% of the land area 75% live within 1000 km of the sea 90% lives north of the equator where the larges proportion of the total land mass is located (63%) 85% lie in areas < 500m high 85% live between latitudes 68o N and 20o N < 10% live in the southern hemisphere. Most live in temperate low lying areas with fertile soils

10. pg 122 How will the World’s population be distributed in the future? By 2030 the population of E and S Asia will be over 4.1 billion people, about 1.8 billion more than now. They will comprise 44% of the world’s population on 13% land area Areas of the Earth that are not presently inhabited will remain uninhabited Within the inhabited areas there will be a core – periphery polarisation Rapid urban pop growth will continue in LEDCs

13. Homework question…. Explain why the distribution of the world is uneven.

26. Describe the global distribution of population. You should include these terms in your answer: sparsely populated, densely populated Using only an annotated map, explain how physical, historical, cultural and political factors have affected the distribution of a country of your choice.
