Concerns have been raised over the potential of charter schools to re-segregate the nation's schools. This concern has been expressed mostly with respect to students with disabilities and with respect to ethnic and/or racial minorities. In this study, the enrollment statistics for charter and contiguous non-charter public schools in a large urban district were compared with each other and with district enrollment averages by school level (elementary, middle, and senior schools). Findings indicated that very few enrollment percentages of charters and of noncharters were comparable with District averages on gender, ethnicity, participation in the free/reduced lunch program (FRL), limited English proficiency (LEP), and students in exceptional student education (ESE). Indeed, contiguous charter and non-charter public schools were more likely to resemble each other than District averages. However, charters and non-charters differed significantly from each other on the number of schools that had "low" and "high" enrollments of students participating in FRL, of LEP, and of ESE students.
