School district boundaries define more than just the area where a certain group of children attends a given set of schools. They also determine the taxing jurisdiction that supports those schools with local property taxes. Big differences in property value can lead to large funding gaps, even between neighboring districts. These disparities in property values are the legacy of discriminatory housing policies explicitly intended to segregate neighborhoods by race and class. The school district lines drawn onto this divided landscape then replicate segregation and inequity in schools. But our current district borders need not be permanent. They can be redrawn to produce better outcomes for students and their schools. In a new research report, New America's Education Funding Equity Initiative analyzes nearly 25,000 pairs of adjacent school districts to measure how district borders create deep economic and racial divisions, producing radically different educational resources and experiences for students in different districts--even districts that are right next door to each other. It also features stories about these disparities told by local educators and families. An accompanying multimedia story shows what these divides mean for American school districts and communities, and an interactive national map and data tool allows users to explore American school districts and the borders that surround them.
