During Phase I both the CBR and the CDR are high, but balance out. Many children die before maturity, and so even though many are born the population does not grow. A population can remain in this state for long periods of time. It corresponds to human populations before industrialization.
In Phase II the CDR declines, as it did during the early industrial period. Advances in hygiene and a better understanding of disease led to dramatic declines in child mortality. Because children are still seen as assets rather than liabilities, the CBR remains high. This causes a rapid expansion of the population, if the food supply is sufficient. An increased food supply brought about the the Agricultural Revolution of the 18th century permitted the population to expand rapidly.
In Phase III the CBR begins to fall but still exceeds the CDR. Urbanization makes children a liability, because there is no farm work for them to do. They must be fed and cared for, and do not contribute to the family's income. The CDR also continues to fall, but not as dramatically.
The Phase IV is characterized by low CDR and low CBR, which lead to a steady population. Both CDR and CBR level off at values where the population can replace itself, but not expand. The CDR is equal to the CBR, but now at a lower level. Fewer children …show more content…
In developing countries, most women have very few prospects other than becoming wives and mothers. Their self-worth is based on bearing sons, and because children often die before maturity, they have "extra" children so as to ensure some living adult offspring. Even if contraception is available, women often choose to have many children, or feel pressure from their husbands and in-laws to continue having children. In India, women are often beaten and adondoned for failure to produce a
