Most low-income students received financial aid: 78 percent at public 2-year institutions, and 86 to 98 percent at 4-year institutions. Among middle-income students, less than half received aid at public 2-year institutions (40 percent), but 71 to 93 percent did so at 4-year institutions. Students from both income groups were more likely to receive aid at private not-for-profit nondoctoral institutions than at any other type of institution.
