The impact of public-sector expenditures for contraceptive services in California.

A methodology previously used to calculate the number of unintended pregnancies averted nationally through publicly funded contraceptive services has been adapted for a state-level analysis in California. An estimated 136,800 unintended pregnancies--which would result in approximately 36,000 births, 85,100 abortions and 15,700 miscarriages--are averted each year because publicly funded contraceptive care is available from clinics and private physicians in California. Federal and state expenditures of $46 million for contraceptive services in California in FY 1989 resulted in an estimated savings of $232-$509 million in public costs for abortions, for prenatal and maternity care and for medical care, welfare and supplementary nutritional programs during the first two years after a birth. These savings represent an average of $7.70 saved for each dollar spent to provide contraceptive services. This savings/cost ratio is 75 percent higher than that previously estimated for the United States as a whole.
