The Demographic Transition

Today in class we were introduced to the Demographic transition. It is basically what we have been learning about population but put into stages. The first stage would be very high birth rate and very high death. When we had to hunt for food and gather. Stage 2 would be the start of the countries industrial revolution. When there birth rate is high and there death rate is declining, high NRI. They are obtaining better qualities to live in. Stage 3 would be moderate growth. Rapidly declining birth rate and moderately declining death rate. Moderate NRI. Finally stage 4, restart back to stage 1. Very low CBR and low or slightly increasing CDR. Zero or negative NRI. There population isn't growing, somewhat declining.

Reviewed over quiz questions
