The economic impact of Pennsylvania colleges and universities on the community, region, and state and the immediate new economic return for public and private dollars were assessed. One study phase involved the collective impacts of all of the accredited 2- and 4-year degree-granting colleges and universities in Pennsylvania upon the total economy of the state, based on data from 99 higher education institutions. Colleges were also invited to volunteer to conduct individual studies of their community economic impacts. A brief summary is presented of the results of each of the 17 case study reports submitted by individual colleges and universities as of October 1971, along with a description of the suggested methodology and collective observations regarding case study results. For the institutional case studies, information is presented on demographic and economic characteristics, including population, income, employment, service area business activity, enrollment and degrees conferred, revenues, capital assets, expenditures, the institution as an employer/property owner/investor, and tax revenues received by the city and county from college-related sources. In addition, excerpts are presented from the report of the statewide higher education economic impacts, which is entitled "Higher Education: Its Economic Relationships." A diagram illustrates how revenues received by colleges are rechanneled back into the economy in the form of salaries to employees, taxes and fees to governments, and payments for goods and services purchased from businesses. Enterprises that are economic by-products of the college include facilities for housing and feeding students, health services and retail functions, research laboratories, and athletic activities. A case study report summary outline is appended. (SW)
