This study presents an expanded methodology for economic impact analysis to measure the impact of a community college, South Plains College (SPC), Texas, on a specified nonlocal economy. The research had four parts. First an economic impact study was conducted for SPC and its impact on the local economy of Hockley County, where the college is located. Second, existing economic impact analysis methodology was expanded based on a modified Ryan model (a variation of the Caffrey-Isaacs model) to facilitate the estimation of the economic impact on a nonlocal economy. Third the method was applied to the nonlocal economy, Lubbock County, which is adjacent to Hockley County. Fourth, the findings of both impact studies were evaluated to identify differences in method and relative impacts in both economies. The study found that differences in the method rested chiefly in writing the impact formulas and in collecting the impact data. Analysis showed that, in Hockley County, there was a return to the economy of about four dollars for every one dollar of taxes invested in the college, and that Lubbock County experienced a total business volume impact of $21 million. Comparison of impact volume between the two showed that total impact differed by only approximately $86,000. (Contains 30 references and 12 figures.) (JB)
