Between 1978 and 1988, as district residence requirements were liberalized for California community college attendance, enrollments in the Los Angeles Community College District (LACCD) declined sharply. A study was conducted to track the interdistrict flow of students between 1981 and 1987 within the context of total enrollment changes since 1975. Study findings included the following: (1) the outflow of students from the LACCD increased from fall 1981 through fall 1987, but at a rate of only 2% between 1985 and 1987, compared to a 50% increase between 1981 and 1985; (2) 21,607 district residents attended non-LACCD colleges in 1981, 25,189 in 1983, 32,477 in 1985, and 33,221 in 1987; (3) the inflow of students to the LACCD remained fairly stable between 1981 and 1987, with 5,930 non-district residents enrolled in 1981, 6,063 in 1983, 5,080 in 1985, and 5,808 in 1987; (4) LACCD residents who attended community colleges outside of the district tended to be somewhat younger, and were more likely to be full-time, transfer-oriented students; (5) between 1981 and 1987, the ethnic distribution of outflow students moved much closer to that of the LACCD enrollees as a whole; (6) 26% of all LACCD residents attending any community college were enrolled outside of the district; (7) by the time of the study, several neighboring districts had become dependent on LACCD residents for the maintenance of their own enrollments, with neighboring colleges drawing from 58% to 20% of their students from the LACCD; and (8) the theoretical revenue losses to the LACCD resulting from large outflow imbalances were estimated at $45 million in 1987-88.
