Between the community campuses and the main Anchorage campus, over 20,000 undergraduate, graduate, and professional students are currently enrolled at UAA. This makes it the largest institution of higher learning in the University of Alaska System, as well as the state.
In the 1970s, the university began a period of rapid growth. Enrollment at the beginning of the decade stood at 6,629, including 2,724 women. To accommodate the growing student population, UAB acquired land in the Southside. UAB Mini Park (the predecessor to The UAB Green) was dedicated in 1977.
