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:
“A transition from an author’s books to his conversation, is too often like an entrance into a large city, after a distant prospect. Remotely, we see nothing but spires of temples, and turrets of palaces, and imagine it the residence of splendor, grandeur, and magnificence; but, when we have passed the gates, we find it perplexed with narrow passages, disgraced with despicable cottages, embarrassed with obstructions, and clouded with smoke.”
—Samuel Johnson (1709–1784)
