The "Residence and Migration of College Students" machine-readable data file (MRDF) is based on data gathered periodically as a part of the Higher Education General Information Survey (HEGIS). Data are collected from the regular HEGIS universe of over 3,000 accredited higher education institutions in the United States and its outlying territories. The response rate is typically over 90%. In 1984, 3,379 institutions were queried and 2,931 (87%) responded; records for non-responding institutions were zero-filled rather than imputed. Records in each file are arranged by institution. Each record consists of basic institutional characteristics (e.g., calendar system used, current total enrollment, enrollment range, highest level of offering, institution affiliation, institution name, land grant status, race and sex ratios of the student body, etc.), followed by data for all students when they are first admitted as undergraduate, graduate, unclassified, or first-professional. Undergraduates are categorized either as first-time freshmen who have just completed high school, or other first-time freshmen, or as transfer students. Students are also categorized as full-time or part-time. Foreign students are grouped separately under the above categories. Extension students are reported along with main campus data; students in non-credit adult or extension courses are not included. Student variables include: residence, home state, sex, full-time or part-time, foreign or domestic, and category of student (as discussed above). POPULATION: Higher Education Institutions (73,000).
