A method for calculating rates of induced abortion.

Accurate measurement of induced abortion is necessary for understanding the fertility dynamics of a population and for making projections about the future. Changes in abortion rates can amplify or dampen the impact of changes in contraception. This paper presents a methodology for calculating marital induced abortion rates from observed marital fertility and contraceptive prevalence and for modeling the impact of substituting contraception for abortion on future fertility. The methodology is validated against observed abortion complications in three populations, and the impact of substituting contraception for abortion on expected fertility is demonstrated.

A cost-benefit analysis of the Mexican Social Security Administration's family planning program.

A cost-benefit analysis of the family planning program of the Mexican Social Security System (IMSS) was undertaken to test the hypothesis that IMSS's family planning services yield a net savings to IMSS by reducing the load on its maternal and infant care service. The cost data are believed to be of exceptionally high quality because they were empirically ascertained by a retrospective and prospective survey of unit time and personnel costs per specified detailed type of service in 37 IMSS hospitals and 16 clinics in 13 of Mexico's 32 states. Based on the average cost per case, the analysis disclosed that for every peso (constant 1983 currency) that IMSS spent on family planning services to its urban population during 1972-1984 inclusive, the agency saved nine pesos. The article concludes by raising the speculative question as to the proportion of the births averted by the IMSS family planning program that would have been averted in the absence of IMSS's family planning services.

Sterilization and the birth rate.

Sterilization remains irreversible for all practical purposes, but as its procedures become more feasible in developing countries, the question of its potential contribution to fertility decline vis-à-vis other contraceptive methods has increasing significance for family planning program administrators. This question is examined by means of a model that calculates births averted in defined time durations from the acceptance of various contraceptive methods by women of different ages. The findings suggest that without ready access of the population to reversible contraceptive methods that are attractive to birth spacers and tentative birth terminators, the rate of fertility decline is not likely to be satisfactory regardless of the availability, promotion, or popularity of sterilization.
