Population Density

1. Amman, Jordan 2. The Alps, France

PowerPoint Presentation:

Population Density- describes the average number of people living in a given area( km²). It is calculated by dividing the total population by the area of land. Densely populated- high population density Ex. north – east USA Sparsely populated – low population density Ex. Central Australia

PowerPoint Presentation:

Factors influencing where people live Attracts people to live in some areas Flat land Employment Fertile soil Reliable water supplies Natural resources Good communication Few people live in some areas Steep relief Infertile soil Marshy land Extremely cold climate Arid climate

PowerPoint Presentation:

Different types of land use 1. Housing/residential 2. Industrial 3. Commercial/businesses/offices 4. Shops 5. Leisure facilities / or example 6. Educational/schools/colleges 7. Health care/hospitals

PowerPoint Presentation:

Low population density in Namibia Republic of Namibia Capital – Windhoek Population -  2011 census 2,100,000 [1]  - Density2.54/km 2  ( 235th ) 6.6/sq mi Land area-  Total825,418 km 2  ( 34th ) 318,696 sq mi GDP- per person US $ 5200 Karas Region Geography- Desert, with hot, dry climate. Rainfall is sparse and erratic and there are prolonged periods of drought so as a result the area is a sparsely populated.

PowerPoint Presentation:

High population density in Japan Capital- Tokyo Official language – None Population – 126 million density - 337.1/km 2   873.1/sq mi Area - 377,944 km 2 145,925 sq mi Islands – 6852 4 largest islands are Honshu, Hokkaido, Kyushu and Shikoku Borders - Sea of Japan , China, North Korea, South Korea, Russia to the east, Sea of Okhotsk to the north ,East China Sea and Taiwan to the south

PowerPoint Presentation:

Northern Japanese Alps Low density Rural areas Few people live here because: There is not enough flat land to grow food on 2. Soils are thin, acidic and infertile 3. Many areas are isolated and remote as the winding roads are poor and there are few if any other communications 4. There is little work except forestry as there are few natural resources 5. The climate is often extreme, with long cold winters and heavy ran or snow

PowerPoint Presentation:

A village in Gifu prefecture, Japan High- density rural areas Densely populated because: Crops can easily be grown on the fertile soils of the flat or gently sloping land It is easy to use farm machinery on flat land the warm temperate climate means a variety of crops can be grown 4. Good roads and railways make it possible to live in the countryside and work in the cities

PowerPoint Presentation:

Tokyo cityscape High- density urban areas Densely populated because: On the flat land is it easy to build - town and cities - factories, offices and other commercial buildings - road and rail networks - airports 2. On the coast there are many ports and harbours which led to - the import raw materials - the export of manufactured goods - the development of a fishing industry

PowerPoint Presentation:

Vocabulary Steep – high or lofty as of a hill Infertile – unproductive Marshy- soft, wet , swamp Arid – dry, w/o moist, extremely dry Tarred – smoke solid components, coal- tar Gravel – small stones or pebbles Choropleth  a symbol or marked and bounded area on a map denoting the distribution of some  property

PowerPoint Presentation:

Population distribution Is the way that the population is spread out over a given area from a small region to the Earth as a whole. West coast Ireland Sparsely populated Extremely cold climate Infertile soil There's is a little work or job available Communication is not convenient Areas are isolated

PowerPoint Presentation:

Cairo Egypt Densely populated Flat land - easy to build infrastructures, cities - factories, offices, roads, railways - airports 2. Convenient communication 3. More employment available 4. Good climate 5. Trading is easy

North America – one of the 7 big continents of the world Low population density USA- 31/km² Canada- 3/km² Cold , dry and mountainous regions Low temperate in the North Steep relief Areas are isolated Hot climate in the desert part
