Older undergraduate students tend to enroll in private and for-profit 4-year universities. Once adult students reach the ages of 35-39, data revealed that enrollments shift from public (3.1%) to private (3.4%) 4-year universities. Enrollment for students aged 65 and older are equal (0.2%) among institution type. Enrollment percentages for adult students over the age of 25 at for-profit 4-year universities are higher than both public and private 4-year universities until the age of 65 and older. For this older age group, the data revealed that the percentage of adult students at for-profit 4-year universities is 0.1% (Caruth, 2013).
