The Demographic Transition

Today in class we learned about demographic transition. Demographic transition is a process of change in a society's population from high crude birth and death rates and low rate of natural increase to a condition of low crude birth and death rates, low rate of natural increase, and higher total population. Stage 1 is low growth. The low growth is caused by very high CBR, very high CDR, and very low NIR. Stage 2 is high growth. The high growth is caused by high CBR, rapidly declining CDR, very high NIR. Stage 3 is moderate growth. The moderate growth is caused by rapidly declining CBR, moderately declining CDR, and moderate NIR. Stage 4 is low growth. Low growth is caused by very low CBR, low or slightly increasing CDR, and zero or negative NIR. Those are the four stages of demographic transitions. We got our quizzes back and I got a 88%. Its not the best but its not bad. I only got 3 wrong.
