The Demographic Transition pt.2
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.
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.
