Enrollment at California state universities has increased by almost 95,000 students in the last five years, increasing housing problems in campus communities, according to a Public Policy Institute of California report.

College students in California have to compete for affordable housing in an already crowded and expensive housing market. The state is home to four of the eight most expensive rental markets in the country, according to the report. And areas once considered affordable, such as Sacramento, Fresno and Bakersfield, have seen rental costs skyrocket in recent years.

Students who live on campus are more likely to remain in college, although most students at University of California and California State University campuses move off campus after their freshman year, according to the report. At many campuses university housing is more costly than private housing.
