Data on freshmen at the University of North Carolina at Chapel Hill are presented and compared to data of comparable institutions as part of the research of the Cooperative Institutional Research Program (CIRP). The study deals with the class of 1980 (enrolled, fall 1976) and the class of 1981 (enrolled, fall 1977). The two classes of entering freshmen are profiled using data submitted on state and federal reporting forms. The CIRP Freshman Survey data are presented in selected areas as a series of tables that allow comparisons of the class by sex with other freshmen populations entering in the same year. Data are shown by sex for each of the following groups: Chapel Hill freshmen, freshmen entering highly selective public universities, freshmen entering highly selective private universities, and freshmen entering all universities. Some brief highlights of the survey are noted in the text along with some comparisons between the classes of 1980 and 1981, and possible implications of the data for planning and decision making at the University of North Carolina at Chapel Hill are presented. Suggestions for futher campus uses of the data obtained through the annual surveys are also offered. (SW)
