We examine the gap in broadband access to the Internet between minority groups and white households with geographically fine data on DSL subscription. In addition to income and demographics, we also examine quality of service and competition as components of the Digital Divide. The gaps in DSL demand for blacks and Hispanics do not disappear when income, education, and other demographic variables are accounted for. However, lack of competition is an important driver of the Digital Divide for blacks. Service quality is an important determinant of demand, and ignoring it masks the true size of the DSL gap for Hispanics.
