This report offers data on regional population growth and on educational access based on commuting times to and from campus facilities to document the need for the establishment of a minimum of three permanent educational centers in the west part of Riverside County, California. After part I presents an overview of the study, part II explains the factors influencing the unprecedented growth of Riverside County and presents the Riverside Community College District's application for the approval of two permanent educational centers and the Mt. San Jacinto College District's application for the approval of an additional center. Part III profiles population trends in Riverside County and adjacent areas, including information on travel times to existing educational facilities. Part IV offers demographic data for the two districts, covering family income, ethnicity, employment, accessibility of the proposed sites to the population to be served, household size, transportation routes, and labor market. Additional data on community support for the proposed centers and the anticipated effects on adjacent institutions are provided. After part V looks at enrollment trends and projections for both districts, part VI presents an interdistrict and regional study of programs, which compares and analyzes existing programs; identifies duplicated, shared, and unduplicated programs; assesses labor needs and the regional labor market; and discusses corporate education needs.
