Designed for use by community college personnel, this handbook provides information necessary to conduct a study of the impact of a community college on the business volume and other economic aspects of the community. Section I explains models for assessing the following seven types of economic impact: (1) college-related local business volume; (2) value of local business property committed to college-related business; (3) expansion of local banks' credit base; (4) college-related revenues received by local governments; (5) operating costs of government-provided services applicable to college-related influences; (6) number of local jobs attributable to the presence of the college; and (7) personal income of local individuals from college-related jobs and business activities. Directions and questionnaires for surveying college staff and students are provided in section II. Section III lists information needed to complete an economic impact study, and section IV presents a process to calculate economic impact in seven areas. Finally, summary information is provided related to the concept of the multiplier, along with data on the percentage of each county's population enrolled in each community college district, and selected references.
