Early estimates show 29,910 students are enrolled at the University of Colorado's Boulder campus, down 1.7 percent from last year.
The CU system said Wednesday that new freshmen account for about 5,500 of the total. The Boulder campus had about 5,600 new freshmen last year.
Tuition at CU's College of Arts and Sciences in Boulder is $8,056 for in-state students or $29,946 for new out-of-state students.
About 22 percent of new freshmen this year are racial minorities. The number of international students rose 14 percent to about 1,900.
However, CSU saw record enrollment this year, it's the fourth straight year reporting growth.
The school on Thursday reported its largest-ever freshman class of 4,544 students and total enrollment of 26,769 students. The overall enrollment is just above last year's total of 26,735 students, which was then an all-time high.
CSU says 872 racially and ethnically diverse freshmen make up 19.2 percent of this year's incoming class, while out-of-state students make up about one-fourth of the freshman class. The university says nearly one in four new freshmen will be the first in their family to earn a college degree.
Despite high student enrollment, Colorado State University President Tony Frank is warning of a future without state funding for higher education in seven to 10 years if Colorado doesn't change the way it manages its resources.
Frank said Thursday in his annual fall address that CSU has begun planning for the possibility of no public funding.
Public universities and colleges have been a target of cuts as state legislators dealt with tight budgets in recent years and laws that limit state taxing and spending.
Frank says the university's long-term plan will focus on increasing enrollment of out-of-state students who pay more tuition than in-state students, ensuring CSU is a school of choice within Colorado, and pushing for excellence.
The university also has been cutting costs and has embarked on major fundraising initiatives.
