To examine whether facility availability impacted abortion utilization, we examined the relationship between facilities and abortions at the county level. We used both abortion rates and ratios because each measure reflects different contexts; abortion rates (abortions per 1000 female Medi-Cal FFS enrollees of reproductive age) relate abortions to the population ‘at-risk’, while abortion ratios (abortions per 1000 Medi-Cal FFS paid births) relate abortions to a measure of fertility. T-tests comparing county level abortion rates and ratios between counties with and without a facility providing 50 or more Medi-Cal FFS abortions found no significant associations (p = 0.29 & p = 0.79, respectively). A linear regression of county level abortion ratios by number of facilities (providing 50 or more abortions) per 10,000 enrollees also found no significant association (p = 0.51), however, the abortion rate was significantly positively associated with the number of facilities per 10,000 enrollees (p = 0.02) (see Fig. 1).Fig. 1County Medi-Cal abortion rates vs. number facilities proving 50+ abortions per 10,000 female reproductive-aged enrollees
