Earning a postsecondary degree is a well-established pathway out of poverty, and degrees are especially life-changing for women raising children on their own. Analysis by the Institute for Women's Policy Research (IWPR) finds that in 2016, single mother poverty rates were an average of 33 percent lower at each additional level of education, with bachelor's degree attainment or higher leading to decreases in single mother poverty of over 40 percent compared with one degree lower. While the share of single mothers' living in poverty has decreased over the last six decades, progress has been slow, and poverty rates remained significantly higher than rates among other family types: single mothers have been an average of nearly six times as likely to live in poverty as married couple families since 1974. IWPR estimates that if one quarter of single mothers with only a high school diploma or some college in 2016 had earned an associate or bachelor's degree, poverty among all single mothers would have declined by eight percent--more than three times the rate seen over the last decade. Greater access to supportive services, such as affordable child care, targeted financial aid, and holistic case management would improve single mothers' ability to enter college and persist to degree completion.
