Population Pyramids

Shows how a countrys population can be split into groups of men and women of different ages.


  • Stage One: High birth rate, rapid fall in each upward age group due to high death rates, short life expectancy - concave pyramid
  • Stage Two: Still a high birth rate, fall in death rate as more living in middle age, slightly longer life expectancy
  • Stage Three: Declining birth rate, low death rate, more people living to an older age
  • Stage Four: Low birth rate, low death rate, higher dependency ratio, longer life expectancy
  • Stage Five: Low and falling birth rate, falling fertility rate, ageing population

  • Kenya is an LEDC
  • women live longer
  • 30,507,979 people
  • more women over the age of 39 than men
  • more men under the age of 39
  • birth rate is remaining high and death rate is high
  • children are an asset as they are needed for farming, they die young so more children are born

  • 0-15 years more men from the younger ages
  • 16-39 there are more women for the middle ages
  • 40-64 similar numbers
  • 65+ years more women
  • birth rate not very high
  • death rate not very high
  • population 1,268,853,362

CASE STUDY!!!! - Stage Four to Five - Germany

  • Population begins to decrease
  • birth rate decreases because children are expensive to raise
