Since 2008, Sallie Mae has surveyed American families with an undergraduate student about their attitudes toward college and how they paid for it. For the past ten years, the "How America Pays for College" research has provided insight regarding families' belief in the value of a college education, how they are making college more affordable, and the relationship between education-related choices and cost considerations. Sallie Mae has again partnered with Ipsos, a global independent market research company, to conduct this study. "How America Pays for College 2018" reflects the results of online interviews Ipsos conducted with: (1) 799 parents of children ages 18-24 enrolled as undergraduate students; and (2) 790 undergraduate students ages 18-24. This report includes a full set of response tables associated with each itemized question. Percentage amounts reported may not sum to 100 percent due to rounding. "How America Pays for College 2018" explores how families of undergraduates paid for college in 2017-18--the resources they used, the amounts paid from each source, and the choices they made regarding how to pay for college.
