This report tracks 335 Title-IV participating degree-granting institutions that met the criterion of enrolling at least 25% Hispanic students in 1999 (Hispanic Serving Institutions, or HSIs). The HSIs on this list include public, private not-for-profit, and private for-profit institutions in the United States and Puerto Rico. This report provides a statistical overview of the growth in HSI enrollment and degrees during the 1990s. It also presents an overview of HSI staff in 1999 and describes salary changes from the middle to the end of the decade. This report does not contain an official list of HSIs, but instead attempts to provide a policy-relevant picture of current trends in college education for Hispanics. The broader definition of HSI in this report brings into focus a group of institutions that served 45% of all Hispanic college students in the United States in 1999. Enrollment data are from the 1999 survey of the Integrated Postsecondary Education Data System fall enrollment compliance report. Data show that enrollment in the HSIs grew rapidly between 1990 and 1999. The number of students enrolled increased by 14%, so that the proportion of all U.S. college students enrolled in HSIs grew to 10%. In addition, the number of degrees awarded by HSIs grew by 36% between the 1991-1992 academic year and the 1999-2000 academic year. Data are also presented about faculty and students at HSIs. An appendix contains guides to the tables and sources and a list of definitions. (Contains 4 figures and 38 tables.) (SLD)
