demographic transition model

• stage one

  • birth and death rates are high = low population growth
  • remote tribal communities
  • larger families=larger income from working children
  • overcrowded and unsanitary conditions
  • at present - few countries - war, famine, drought, high deathrate and low life expectancy
• stage 2 -

  • high birthrate and falling deathrate
  • death rates fall because of medicines, diets and better living conditions
  • birthrates high because religion, limits on contraception, large families needed to care for parents
  • LEDC at this stage, falling desthrate from food aid, improved agriculture
  • eg. botswana
• stage 3-

  • falling deathrate + slowly falling birthrate
  • population continues to grow
  • long term aid + their own development, LEDC begin to reduce death and birth rates
  • medical advancements against diseases suchh as cholera and malaria
  • eg.brazil
• stage 4 -

  • deathrates fall due to advanced healthcare, drugs against cancer and heart disease
  • birthrates fall due to lifestyle changes and increased contraception
  • women choose work over family
  • low population growth
  • eg. uk
• stage 5-

  • australia and germany population growth starts declining
