Fall 1980 statistics on the age group and sex of students attending the State University of New York are presented. The major statistical tables array four main student characteristics: age group, sex, load (part-time/full-time), and level (undergraduate/graduate). Part 1 contains summary data for the entire system and each institutional type within the system. For each of the headcount tables in this section there is a corresponding table providing percent distribution arrays of the headcount data. Part 2 contains headcount arrays of students by age group, sex, full- and part-time enrollment, and undergraduate and graduate enrollment level for each individual institution of the state university system. Part 3 contains summarized historical trend data on all students from fall 1974 through fall 1980. In addition, trend data for first-time undergraduate students is included for full- and part-time students and is displayed in headcount and percent arrays. Data are provided for senior colleges, two-year colleges, agricultural and technical colleges, community colleges, university centers, university colleges, health sciences centers, specialized colleges, and statutory colleges. A map of state university institutions is appended. (SW)
