This report presents data on the staff of more than 10,000 postsecondary institutions in the United States including 3,589 institutions of higher education in the 50 states and the District of Columbia. The data were collected in two separate, but related surveys. The first was the "Fall Staff" survey (1989), part of the Integrated Postsecondary Education Data System, which collects information on the number of persons employed in postsecondary institutions by primary occupation, by full-time and part-time status, and by sex. The second survey used was the Higher Education Staff Information Survey, administered by the Equal Employment Opportunity Commission. The data are presented in two main tables and show the number employed in all postsecondary institutions, including institutions of higher education, and the number employed in institutions of higher education alone. Some highlights of the findings include the following: (1) postsecondary institutions employed over 2.6 million persons in fall 1989; (2) women accounted for 51.2 percent of persons employed in postsecondary institutions; (3) professional employees represented 63 percent of all staff in postsecondary institutions, with the majority employed full-time and 57 percent of professional staff being male. Included are eight tables, two figures and appendixes containing data on response status and rates. (Author/JB)
