Data on the sex, ethnicity, age, and geographic origin of undergraduate and post-baccalaureate students enrolled in New Jersey colleges and universities in fall 1980 are given, along with comparisons and trends over the past five years. Increases in the enrollment of women in New Jersey higher education between 1976 and 1980 occurred among part-time undergraduate and full-time post-baccalaureate students (38 percent and 36.5 percent, respectively). Women were the majority of part-time undergraduate students (60.1 percent), while men were the majority of full-time post-baccalaureate students. Women represented 51.1 percent of full-time undergraduate students in fall 1980 and 52.1 percent of part-time post-baccalaureate students. Blacks and Hispanics (combined) increased 19 percent between 1976 and 1980, while whites/others (Asian/Pacific Islander, American Indian/Alaskan Native, and nonresident alien) were responsible for three-quarters of the systemwide growth. Hispanics increased more than did blacks (42.1 percent compared with 11.3 percent). Changes in proportions of minority full-time undergraduate students reflect absolute increases in the public sector and relative stability in the independent sector. Whites/others continue to constitute the vast majority of New Jersey higher education enrollments (85.7 percent overall), ranging from 82.2 percent among full-time undergraduates to 91.8 percent among part-time post-baccalaureates. Conversely, the highest percentage of minorities is among full-time undergraduates (17.2 percent for blacks/Hispanics combined), followed by part-time undergraduates, full-time post-baccalaureates, and part-time post-baccalaureates (8.2 percent). Fall 1980 data for individual colleges are included. (SW)
