This article examines how student movements between traditional public schools (TPSs) and charters—both brick and mortar and cyber—may be associated with both racial isolation and poverty concentration. Using student-level data from the universe of Pennsylvania public schools, this study builds upon previous research by specifically examining student transfers into charter schools, disaggregating findings by geography. We find that, on average, the transfers of African American and Latino students from TPSs to charter schools were segregative. White students transferring within urban areas transferred to more racially segregated schools. Students from all three racial groups attended urban charters with lower poverty concentration.
