Population - The Demographic Transition Model

Stage One
1. Very high birth rate
  1. High infant mortality rate
  2. Uneducated population
  3. Children are future sources of income
  4. Lack of family planning
  5. Religious beliefs
  6. Many kids is a sign of fertility
2. Very high death rate
  1. Very poor hygiene
  2. Bad healthcare (lack of technology)
  3. Average life expectancy is very low
  4. Wide-spread diseases
  5. Lack of clean water
  6. Famine
  7. War
3. Birth rate and death rate are both high anfd fluctuating
4. Examples of stage one may be tribes and parts of Ethiopia
5. Typical of Britain in the 18th century
6. Total population low, increasing slowly
Stage Two
1. Falling death rate because
  1. Healthcare is improving dramatically and quickly
  2. Improved hygiene
  3. Improved sanitation
  4. Improved food production and storage
  5. Improved transportation
    1. Means people can reach hospitals quicker
    2. Food can be transported more easily
  6. Falling infant mortality rate
2. Death rate has fallen but birth rate is still high
3. Examples would be Bangladesh, India and Nigeria
4. Typical of Britain in the 19th century
5. Total population increasing massively
Stage Three
1. Birth rate starts to fall
2. Death rate continues falling
3. Total population is still increasing
4. Reasons for falling birth rate
  1. Family planning becoming more common
  2. Lower infant mortality rate
  3. Increased mechanization means less workers are needed
    1. Means children are no longer future sources of income
  4. Increased standard of living
  5. Changing status of women
5. Examples include China and Brazil
6. About the point at which a country goes through the industrial revolution
7. Britain at the end of the 19th century, start of the 20th century
Stage Four
1. Low birth rate
2. Low death rate
3. Total population is steady
4. Sometimes birth rate may fall below death rate
5. Known as low fluctuating
6. Examples include Canada, the USA and Britain
7. Britain today
  1. Post 1940
Stage Five
1. Birth rate stays low
  1. May even decrease slightly
2. Death rate starts to increase
3. Results in a declining population
4. Results in an ageing population
  1. Causes pension problems and housing problems (bungalows)
5. Examples are Russia, Germany and Japan
6. Death rate may rise slightly due to poor dieting and smoking/alcohol consumption
7. Britain in the close future (maybe 2050)
