Recent mass closings of schools have rocked cities across the United States. Though these urban closures--and widespread community protests--have made headlines, rural schools have also long experienced and opposed the closure of their schools. A large body of research examines these urban and rural closures from a variety of perspectives, including their economic motivations and policy implications. This review reexamines this literature, looking across context to show how school closure can produce spatial injustice. Advocates argue that closures further academic opportunity, efficiency, and equality. But our analysis shows that closures are unevenly distributed, disproportionately affecting places where poor communities and communities of color live, and they can bring negative effects, harming students and adults and reducing their access to an important educational and community institution. We conclude with recommendations for research and practice.
