  7. 7. STAGE 3:STAGE 3: LATELATE EXPANDINGEXPANDING Birth rates fall rapidly (20 per 1000), while death rates continue to fall (15 per 1000) The fall in birth rate may be due to: - Family planning (contraceptives, Sterilisation, abortion, etc) - A lower infant mortality rate, therefore less need to have so many children. - Increased industrialisation: fewer labourers are needed. - Increased desire for material possessions (cars, holidays...) - Emancipation of women
  8. 8. STAGE 4:STAGE 4: LOW FLUCTUATINGLOW FLUCTUATING Both birth rates (12 per 1000) and death rates (10 per 1000) remain low, fluctuating slightly to give a steady population
