Population

  1. 1. J a d e V e r n o n sparSely & denSley populated areaS
  2. 2. An area can be… Sparsely populated Few people living in an area. Densely populated Lots of people living in an area. Population distribution means the pattern of where people live
  3. 3. This is a population density map. It shows how many people live in an area.
  4. 4. Physical Factors which affect population density
  5. 5. Human factors which affect population density
  6. 6. The world's population is growing very rapidly. In 1820 the world's population reached 1 billion . In 1990 it reached 6 billion people. This rapid growth in population has been called a population explosion . Population is affected by the birth and death rate in a country
  7. 7. Life Expectancy The average age a person can expect to live to in a particular area. From this figure you can determine many features of a country. For example standard of living. As a general rule the higher the life expectancy the more healthy a country is.
  8. 8. The Demographic Transition Model shows how population changes as a country develops but does not involve migration. The model is divided into four stages. Stage 1 Birth rate and death rate are high - low natural increase - low total population Stage 2 Birth rate is high - death rate is falling - high natural increase (population growth) Stage 3 Falling birth rate - low death rate - high natural increase (population growth) Stage 4 Birth rate and death rate is low - low natural increase - high total population
