Densely Populated: Japan

BACKGROUND

  • One of the most densely populated countried in the world
  • Population density of 339/ square km

The distribution is extremely contrasting from place to place

Few people live in the low-density rural areas beacuse

  • the land is not compatible for food growth and the soil is poor, aswell as extreme climates
  • many areas are completely isolated and there is little  

Lots of people live in high-density rural areas because

  • good soil and flat land, good climate
  • not as isolated

Lots of people live in high-density urban areas because

  • lots of flat land - easy to build everything a city needs
  • coasts are very useful

  • Low GDP ($5200)
  • Population density of 2.5 square km
  • Hot, dry, desert-like climate
  • Economy is dependant on the extraction and processing of minerals for export
