Colleges established in urban and rural areas can aid in community and regional development. The purpose of this study is twofold: first, to describe the social and economic impact of the college on various communities, and second, to predict institution-related inputs that are basic to this impact. Important factors in community development include increases in retail trade, property values, family income, educational levels, and social interaction. The college presence can strongly affect these factors, based on 5 major inputs: professional and auxiliary staff, local and nonlocal students, college purchases, physical factors such as buildings, visitors, and miscellaneous agents. Economic impact of the college basically depends on the proportion of staff and students living in the college community and the proportion of their expenditures made through local vendors. Social impact depends on the extent of staff and student interaction with local residents and institutions. Locational analysis of social and economic input combined with the predictive techniques demonstrated in this study can be useful in coordinating educational planning with area development and public investment decisions.
