Data on 1980-1981 student enrollments in the University of Nevada system are presented with tables and charts divided into two sections: full-time equated enrollment or credit loads at campuses, and headcount enrollment. The tables report only those course loads or enrollments that are entitled to state funding (private or federally-supported courses and enrollments are omitted). The figures in the tables are net (i.e., withdrawals within the add-drop period have been subtracted from the totals). The figures are also annualized, which means that fall and spring registrations (plus mini-session credits or students) have been totalled and then averaged to show the mean effort of a campus or unit for the year. For the University of Nevada's Reno and Las Vegas campuses, data are presented on credit production by college (subject area) for 1979-1980 and 1980-1981. Data are also presented on credit production for developmental studies, occupational studies, and general education for Clark County Community College, Northern Nevada Community College, Truckee Meadows Community College, and Western Nevada Community College. Headcount enrollments for the universities and community colleges of the state system are presented for the fall semester from 1971-1972 through 1980-1981. Headcount student enrollments are also provided by sex, along with declared major by sex. Resident student enrollment by county is provided for the University of Nevada at Reno and Las Vegas, along with data on in-migrants from out-of-state and from other countries. Lastly, data on 1979-1980 student out-migrants (Nevada residents attending college in other states) are presented. (SW)
