Summarize the main stages of the demographic transition and the reasons why a society moves from one stage to another

What will be an ideal response?


Answer: In Stage 1 there are high birth rates and high death rates, as a result, the population is fairly stable. In Stage 2, typically due to advancement in medical technology, the death rate falls, but birth rates remain high. This creates a rapid population increase. In Stage 3, people realize that children are expenses rather than assets, and the birth rates drop. This decrease in birth rates causes the population increase to slow. In Stage 4, the populations become stable again with low birth rates and low death rates. Stage 5 is where the death rates exceed the birth rates and populations decline.
