This report (the third of three volumes) presents the results of the annual survey of the geographic origins, or permanent residences, of students attending institutions of the State University of New York during the fall 1990 term. The report includes tabular data on all credit course students and all institutions of the State University system. Volume III presents information on trends from 1959 through 1990, provided by individual institution and institutional type, regarding the percent of the institution's full-time students who came from the institution's area of location, from New York State but outside the area of the institution's location, from the United States but outside of New York State, and from a foreign country. In addition, there are displays of a seven year trend in the New York origins of full-time, first-time students for each State University of New York (SUNY) institution or institution type. Finally, the report shows a seven year trend for full-time, first-time students from each New York county (along with Long Island, New York City, and New York State totals) who enrolled at SUNY institutions. A publications list is provided. (GLR)
