The Demographic Transition pt.1
Demographic transition is a process of change in society's population form high crude birth rate 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. This consists of four stages. Stage 1: Low Growth, Stage 2: High Growth, Stage 3: Moderate Growth, Stage 4: Low Growth.
Stage 1: Very high CBR, Very High CDR, Very Low NIR- today no country remains in stage 1, every nation has moved on to at least stage 2. When food was easily obtained, a region's population increased; the population declined when people were unable to locate enough animals or vegetation nearby.
Stage 2: High CBR, Rapidly Declining CDR, Very High NIR- rapidly declining death rates and very high birth rates produce very high natural increase. The Industrial Revolution involved major improvements in manufacturing goods and delivering them to market. As a result there is an unprecedented level of wealth. What pushed some developing countries into stage 2 was the Medical Revolution. Medical technology invented in Europe and North America has diffused to developing countries. Improved medical practices have eliminated many of the traditional causes of death in developing countries and enabled more people to experience longer and healthier lives.
