More on Demographic Transitions
During class we reviewed demographic transitions so that we can understand them better. We clarified what it really is and what the stages mean.
Stage 1 is when both the birth and death rate is high. Since they are both high they cancel each other out, therefore, making the natural increase stable. This stage usually happens in developing countries, and most countries are out of that stage.
Stage 2 is when the birth rate is still high, and the death rate falls dramatically. This causes an increase in the RNI. This usually happens when the country is going through some sort of breakthrough, such as the Industrial Revolution.
Stage 3 is when the the birth and death slowly decrease. The RNI will increase at a much slower rate compared to Stage 2.
Stage 4 is when the birth rate and death are low. It cancels each other out and it makes the RNI stable, or it will slowly increase.
Stage 5 is when the birth is lower than the death rate. The RNI is still stable, but unlike stage 4, it will slowly decrease. While many countries have not reached this stage, there are some that have, such as Japan.
