Demographic Transition
Demographic transition refers to the decline in population mortality and fertility decline with social and economic development. The two major factors affecting demographic transition are the crude birth rate (CBR) and the crude death rate (CDR).
Demographic transition may be considered in four stages. During the first and second stages, the CBR remains high because people still live in agrarian cultures and require farm labour; infant mortality is high. During the third stage, the CBR begins to decline due to women's increasing participation outside the home and a reduced need for farm labour. During the fourth stage the CBR is sustained at a low level, with some countries having rates below the replacement level in other countries.

Famous quotes containing the word transition:
“There is not any present moment that is unconnected with some future one. The life of every man is a continued chain of incidents, each link of which hangs upon the former. The transition from cause to effect, from event to event, is often carried on by secret steps, which our foresight cannot divine, and our sagacity is unable to trace. Evil may at some future period bring forth good; and good may bring forth evil, both equally unexpected.”
—Joseph Addison (1672–1719)
