Inaction to address housing segregation in metropolitan areas has resulted in persistently high levels of residential segregation. As the Supreme Court has recently limited school districts' voluntary integration efforts, this article considers the role of residential segregation in maintaining racially isolated schools, namely what is known about the reciprocal relationship between housing and schooling segregation patterns. In addition, it examines the residential and school segregation indices in the largest metropolitan areas since 2000, comparing relationships between the extent of school and residential patterns and changes in each over time. Finally, I consider the legal and policy options for how residential integration efforts might affect school segregation.
