A nationwide survey of 999 two-year colleges was conducted to collect data concerning computer-related expenditures at the colleges and to facilitate interinstitutional comparisons of these data. The survey collected data on current annual operating expenditures, Fall 1979 credit student headcount, and current annual outlays for: (1) "normal" computer expenditures, i.e., the ongoing operating expenditures devoted to academic and administrative computer support; and (2) "total" computer costs, i.e., the sum of "normal" operating expenditures, plus expenditures for leases, computer development, and computer capital purchases. Analysis of the responses from 308 colleges involved the calculation of ratios expressing both computer-expenditure categories in relation to total college operating expenditures and in relation to college student headcount. For purposes of comparison, aggregate ratios were determined for four institutional size categories based on student headcounts: less than 1,000 students; 1,001 to 5,000 students; 5,001 to 15,000 students; and over 15,000 students. The study report examines limitations, details methodology, and presents the aggregate ratios on a series of tables. The range of findings determined within each size category are also presented. (JP)
