Population Change

Population Change

1. Population Pyramids

   • Stage 4 : Straight sided, Steady birth rate, High life expectancy, Arched Shaped
   • Stage 1 : Wide Base, High Birth rate, High infant Mortality, Low life expectancy, Pyramid shaped (Concaved)
     • Concave = Early
   • Stage 5 : Large Proportion of elderly, Low birth rate, High life expectancy, Light bulbed shaped (Convexed)
     • Convex = Late

2. Controlling Population

   • Anti-Natalist
     • China (Birth controll)
