Day 44- First Day of Demographic Transitions

Today in class we started talking about demographic transitions. Demographic transitions are a type of graph that is used to model birth and death rates and finding what stage of a country they are. There are four stages that everyone agrees with and a fifth that is disputed. stage one is a country with high birth and death rates but a very low rate of natural increase. A stage 2 country is one with a drastically lower death rate and a higher or steady rate of natural increase. The third stage is a stage where the birth rate goes down very fast along with the death rate which doesn't fall as fast. a stage 4 country is one with a very low rate of natural increase and the birth and deaths get close together until they level out. The last stage is one that is disputed and it is a country with a negative rate of natural increase which would mean that the death rate would need to be higher than the birth rate.
