  1. Population Pyramids A visual demographic transition model

  2. Dependency Load : 52.0 Working Population : 48.0 Dependency Ratio : 1.083 Stage 1??? of demographic transition (High Stationary)- The birth and death rate are elevated. Shown by the scooped form of the sides which indicates a large number of deaths from one cohort to the next.

  3. Dependency Load : 44.5 Working Population : 55.5 Dependency Ratio : .802 Stage 2 of demographic transition (Early Expanding) – The birth rate remains elevated but the death rate has dropped. This is shown in the straightening of the sides of the pyramid.

  4. Dependency Load : 37.8 Working Population : 62.2 Dependency Ratio : .608 Stage 3 of demographic transition (Late Expanding) – The birth rate follows the death rate and begins to drop. This is shown in the straightening of the base of the pyramid.

  5. Dependency Load : 35.4 Working Population : 64.6 Dependency Ratio : .548 Stage 4 of demographic transition (Low Stationary) – The birth rate continues to drop and population levels become stationary. The base of the pyramid is pinched inwards and there are more and more older people.

  6. Dependency Load : 31.5 Working Population : 68.5 Dependency Ratio : .459 Stage 5??? of demographic transition (Declining?) – The death rate exceeds the birth rate and population levels may begin to drop as natural decrease sets in.
