This analysis describes levels of diversity in a comparable subset of schools to enable policy-relevant comparisons between charter and magnet schools. We examine schools in districts that had at least five charter schools and five magnet schools in any year since 2000. This selection includes most of the 100 largest school districts since both types of schools developed mostly in large urban districts. This sample is especially relevant to choice policies because it allows comparisons in the same districts where both types of school choice have been tried at a significant level. This study describes the level of segregation in recent decades in large districts which had a significant presence of schools of both types.
