Notes: Columns 2 to 4 report results from separate regressions where the dependent variable is the proportion of the female population age 15–44 who received Medicaid family planning services. All regressions control for state and year fixed effects, the state unemployment rate, the maximum welfare benefit for a family of three in the state-year, and whether the following policies were in place in the respondent’s state at the beginning of the survey year—welfare family cap, TANF, SCHIP, Medicaid coverage of abortion, abortion parental notification requirements, abortion delay rules, and mandated private health insurance coverage of family planning services. They also control for the percentage of the state-year female population in the following demographic groups: married, white, Hispanic, four education groups, and age 15–17, 18–19, 20–24, 25–29, 30–34, and 35–39. All regressions are weighted by the population of women age 15 to 44 in the state and year. Standard errors are adjusted for clustering at the state level. Data on Medicaid family planning beneficiaries for the years 1999–2002 are from the Medicaid Statistical Information System (MSIS), downloaded from http://www.cms.hhs.gov in December 2006. Comparable data for 1992–1998 come from national HFCA-2082 tables, graciously provided to us by Kosali Simon.
