The Demographic Impact of Changes in Contraceptive Practice in Third World Populations
One of the persistent questions in the population field relates to the potential impact of improved contraceptive practices on the level of fertility. This improvement can take several forms: (1) increases in the adoption of contraception by nonusers, (2) increases in the use of the more effective methods, (3) reduction of discontinuation rates, and (4) introduction of new contraceptive technologies. In a recent analysis of European and U.S. data, a methodology to explore several of these questions was developed that can now be applied (with modifications) to Third World countries. We pose two broad questions: (1) What is the implication for future fertility of the prevailing rates of unwanted fertility? and (2) What unwanted births are associated with the nonuse of contraception and with the different methods currently in use, and what would the birth rates be if the mix of methods was improved or if a new method was introduced?
