The "Inventory of College and University Physical Facilities" machine-readable data file (MRDF) is a subfile of the larger Higher Education General Information Survey (HEGIS). It includes basic data on the number of square feet of physical plant space, by type of room, function of room, organizational unit, and instructional program. Data was collected for 1966-67, 1968-69, 1969-70, 1970-71, 1971-72, 1974-75, and 1978-79. The data from the 1978-79 mail survey contains information from approximately 700 randomly selected public and private postsecondary institutions in the United States. One of the primary purposes of the survey was to obtain information as to the accessibility of college facilities and programs to handicapped persons, particularly those with mobility impairments. Section 504 of the Rehabilitation Act of 1973 requires that all programs of institutions receiving federal financial assistance have this accessibility. Data is also available on the gross square feet of building space by age of the building, extending from pre-1900 till 1970 in 10-year intervals. Total floor space is divided into "accessible" and "inaccessible" as pertains to mobility-impaired students. Total square feet are given for planned conversion of inaccessible to accessible space, plus estimated modification costs. Estimated enrollment data for mobility, visually, and acoustically-impaired students are included. The total number of beds in institutionally owned or operated housing is provided, along with the number that can accommodate mobility-impaired students. Finally, the accessibility, inaccessibility, and intended conversion of 19 categories of campus rooms is listed in square feet. The attributes of each institution precede each record, for sorting or selection purposes. POPULATION: Higher Education Institutions (>3,200). TYPE OF SURVEY: National Survey; Sample Survey.
