This study assesses the role of distance to school in the probability of attending university shortly after high school. Students who grow up near a university may avoid moving and added living costs by commuting from home to attend the local university. The distance between the homes of high school students and the nearest university is calculated by combining household survey data and a database of Canadian university postal codes. Students living "out of commuting distance" are far less likely to attend university than students living "within commuting distance." Students from lower-income families are particularly disadvantaged by distance.
