The present study attempts to determine the effect of geographic accessibility of a college on the proportion of high school graduates continuing their education beyond school. Specifically, the study asks not only if communities possessing a college send larger proportions of their high school graduates to college than do communities lacking a local college, but also whether these proportions are differentially affected by different kinds of local postsecondary institutions. Since attention is focused on the variant behavior of different types of individuals as defined by sex, ability, and socio-economic background, college accessibility as defined here is not merely an ecological variable but is considered to be a distribution of educational opportunity over socio-economic space. Findings are presented in this document. (Author/HS)
