This report compares the ethnicities of residents aged 18 and over, Gavilan students, and high school seniors from the cities of Gilroy, Hollister, and Morgan Hill for 1999-2000. The data was gathered from the 2000 census website, California Department of Education Dataquest website, and the campus MIS data warehouse. Some of the key findings of the report are as follows: (1) Gilroy has the closest congruence of students to non-students; (2) Galvin has proportionately more Native Americans but fewer White, non Hispanic from Hollister; (3) for Morgan Hill African Americans and Latinos are more numerous than expected and White, non-Hispanics less numerous than expected at Live Oak High relative to the city population aged 18 and over; and (4) Asians from Morgan Hill are less numerous than expected and Latinos from Morgan Hill are more numerous than expected at Galvin relative to the city population aged 18 and over. Overall, these differences in that data are explained by stating that a higher proportion of "minority" persons as students and fewer "majority" persons as students. The author concludes that further research should be completed in the form of a community survey. (MZ)
