Development and the Demographic Transition Model
The DTM shows how changing birth and death rates affect population growth
Stage 1 is the least developed
Birth rate high because no contraception
People have lots of children because infant mortality is high
The death rate is high because of poor healthcare and famine
Life expectancy is low
(Some tribes in Brazil)
Stage 2 is not very developed
The economy is based on agriculture so people have lots of children to work on farms
Death rates fall because healthcare and diet is better
Life expectancy increases
(Gambia)
Stage 3 is more developed
Birth rate falls rapidly because there is more equality
Use of contraception increases and more women work instead of having children
Economy changes due to manufacturing, income increases and fewer children have to work on farms
Healthcare improves so life expectancy increases
(India)
Stages 4 and 5 are the most developed
Birth rates are low because people want a better QOL
Dependant elderly relatives mean less money to have children
Healthcare is good so death rates are low and life expectancy is high
Income is high
Stage 4 - UK Stage 5 - Japan
