3. Stages of Population growth

   • STAGE 1
     • Stage 1 High Fluctuating A very wide base and a very narrow top representing few old people. The profile is CONCAVE
   • STAGE 2
     • Early Expanding Pyramidal in shape, with a wide base and few people surviving to old age
   • STAGE 3
     • Late Expanding The top of the pyramid is pyramidal, but the base starts to even out as birth rate starts to stabilise
   • STAGE 4
     • Low Fluctuating Straight sided with people living to an old age
   • STAGE 5
     • Natural Decrease Base narrows showing declining birth rate, many people live to an old age

4. Why does population vary from LEDCs to MEDCs

   • Age of Marriage
     • Adults will marry early in thier lives so they will choose to start a family earlier and will have mor years ahead of them to have more children
     • Most Young adults pursue a career berfore marrying so tey will start a family later in life and so thy have fewer children
   • Healthcare
     • Healthcare isnt advanced do death rate increases therefore people have larger families to make up for the rapid deaths
     • Healthcare is more advanced so the death rate isn't high because people are being treated
   • Education
     • Children do not go to school so prents will have more children to help them with agriculture and to look after them in the future
     • It is cumpulsory for children to go to school so they would have health education and they will sudy for longer before they start family planning
   • Status of women
     • Women wont have and education so they spent most of thier lives at home helping thier mothers. they would decide to have children earlier to help them i=around the house
     • Women get educated and so they pursue a career. Therefore they would start family planning later on in thier lives
   • Urban or rural Living
     • If you live in the city, there are more job opportunities so women pursue a career. Therefore they would start a family later on in thier lives
     • If you live in a rural area, there is a lot of agriculture. Therefore women have more children because they would need help with farming
