Between 1973 (the year the Supreme Court ruled in Roe v. Wade that women have the right to decide whether or not to terminate their pregnancies) and 1982, the number of abortion providers increased by 81 per cent. However, between 1982 and 1992, a period of increasing state-level abortion regulation, the number of abortion providers decreased by 18 per cent. We know very little about the factors that influence the willingness and ability of hospitals, clinics, and physicians to provide abortion services over time. Based on state data from 1978 to 1992, the results of this paper suggest that large abortion providers are better able to compete and survive in the market. Also clinics and physicians' offices appear to be gaining market share relative to hospitals. Further, this paper includes analysis of the impact of state-level Medicaid funding regulations on the number, size, and type of abortion provider. These results have important implications for women's access to abortion services and thus have important implications for infant and maternal health.
