Demographic transition

Today in class we continued to discuss the demographic transition and demographic transition model.  We did this by first drawing the model in our notebooks then we rewatched the Kahn academy video.  This video covered how the demographic transitions change from stage  1 to stage 5.  In stage 1 the country has a high birthrate and deathrate this stage occurs before there are any advances in technology that can raise the life expectancy, and better the quality of life. Then stage 2 occurs often when a country has an industrial revolution this causes the death rate to go down, but the birthrate stays the same which causes the population to grow exponentially.  then in stage three as the country continues to develop it reaches stage 3 which is when the birth rate decreases which leads to a smaller increase in the population.  Then when the country continues to develop more women can enter the workforce then fewer children are born which allows the deaths to begin to outnumber the births which cause the population to decrease.  Then there is a possible stage 5 where the country's population continues to decrease.  After this, we do not know what will happen next.
