No state has a better track record on reproductive rights than Oregon, according to a new report.

Seven states and the District received the highest grade, an A-, based on nine indicators chosen by the Institute for Women’s Policy Research (IWPR), a think thank that promotes women’s rights, which did the report as part of its Status of Women in the States series . Ten states earned B’s, 20 earned C’s, nine earned D’s and four states — South Dakota, which ranked last, Nebraska, Kansas and Idaho — received F’s. The Northeast and the West are home to the highest grades, while the South and Midwest scored lowest.
