In 1972, the college was renamed California State University, Humboldt. However, it still continued to be popularly called "Humboldt State." Reflecting this, its name was simplified to Humboldt State University in 1974. Enrollment first reached 7,500 in 1974, and though it has increased to near 8,000 in years since, the university remains one of the smallest in the CSU system. Through the 1980s, mature students became a large part of Humboldt State's student body, and in 1986 40% of the students were over the age of 25. The number has since decreased to 30%.
