Existing studies have examined geographic accessibility to abortion, though to our knowledge no study has examined distances traveled specifically by those using Medicaid funds, or more broadly, by low-income women who may be most burdened by additional travel costs and time. Average distance traveled for abortion has been estimated at the national and regional levels for the general population of abortion patients in the United States , and distance estimates exist at the state level for Louisiana , New York  and Texas [6, 7]. Studies have also used estimates by clinic managers and other key informants at facilities to calculate the proportion of patients traveling distances greater than 50 miles to reach the abortion facility [8, 9]. Estimates of the percent of women traveling greater than 50 miles have changed little over time; in 2005 27% of abortion patients traveled >50 miles, in 2001, 1997, and 1993 an estimated 24% traveled >50 miles [8–10]. A nationally representative survey of abortion patients in 2008 estimated that women traveled an average of 30 miles for abortion services, with a median of 15 miles and that 67% traveled less than 25 miles, 16% 25–29 miles, 11% 50–100 miles and 6% more than 100 miles for care . Controlling for other factors, this study found that rural women and women obtaining second trimester abortions were more likely to travel greater distances, while women of color were less likely to travel long distances than non-Hispanic white women.
