1 Fall enrollment for the academic year specified.
2 For 1997-98 and later years, includes microform and electronic serials.
3 Excludes student assistants.
4 Excludes capital outlay. Expenditure data are reported only by degree-granting institutions with total expenditures over $100,000.
5 Includes student hourly wages.
6 Includes salary equivalents of contributed services staff.
7 Constant dollars based on the Consumer Price Index, prepared by the Bureau of Labor Statistics, U.S. Department of Labor, adjusted to a school-year basis.
8 Includes computer hardware/software, bibliographic utilities/networks/consortia, and "other library operating expenditures" not individually listed.
NOTE: Data through 1995 are for institutions of higher education, while later data are for degree-granting institutions. Degree-granting institutions grant associate’s or higher degrees and participate in Title IV federal financial aid programs. The degree-granting classification is very similar to the earlier higher education classification, but it includes more 2-year colleges and excludes a few higher education institutions that did not grant degrees. Detail may not sum to totals because of rounding.
