Test review
Hi bloggg! Monday we will have a quiz on the demographic transition. This weekend I will study so I get a good grade. The thing we need to know about the Demographic transition is the graph we did in class.
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.Stage 3: Rapidly Declining CBR, Moderately CDR, Moderate NIR- CBR begins to drop sharply. The population continues to grow because of the CDR. But the rate of natural increase is more modest in countries in stage 3 than in those in stage 2 because the gap between the CBR and the CDR narrows. A society enters stage 3 when people have fewer children.

But the rate of natural increase is more modest in countries in stage 3 than in those in stage 2 because the gap between the CBR and the CDR narrows. A society enters stage 3 when people have fewer children.
Stage 4: Very Low CBR, Low or Slightly Increasing CDR, Zero or negative NIR- the CBR declines to the point where it equals the CDR and the NIR approaches zero. This condition is called zero population growth(ZPG), often applied to stage 4 countries. ZPR may occur when the CBR is still slightly higher than the CDR because some females die before reaching childbearing years, and the number of females in their childbearing years can very. Women in stage 4 societies enter the labor force rather than remain at home as full-time homemakers. A country that has reached stage 4 of the demographic transition has in some ways completed a cycle. The total population and CBR and CDR.
The four-stage demographic transition is characterized by two big breaks with the past. The first break- the sudden drop in death rate that comes from technological innovation- has ben accomplished everywhere. The second break- the sudden drop in the birth rate that comes from changing social customs- has yet to be achieved in many countries.

The demographic transition model explains changes in the natural increase rate as they relate to economic and industrial development. This is a process with four stages (some people can argue that there are five) and every country in in one of them. Stage one consists of high birthrates and death rates and consequently very low growth, no country today is in this stage. Stage 2 consists of high growth because death rates have declined and birthrates remain high. When a country goes through the Industrial Revolution. Developing countries have moved into stage 2 because of the medical revolution- diffusion of medical technologies due to LDCs. The sudden decline in death rates that come from technological innovations has now occurred everywhere. Stage 3 countries move from stage 2 to stage 3 when the crude birth rates drop sharply as a result of changes in social and economic patterns that will encourage people to have less children. People are more likely to live in nuclear families in an urban and industrial world. The drop of birth rates comes in social custom has yet to be achieved in many countries. Stage 4 birth rates will continue to decline until the natural increase rate drops to zero. This occurs because of more changes in social customs such as women entering the labor force in larger numbers.
