Single Family Schoolyards: Residential Zoning and School Segregation

Though the Supreme Court’s 1955 decision in Brown v. Board of Education outlawed explicit segregation of public schools, segregation has remained stubbornly persistent in the intervening decades. What explains continuous racial segregation in the absence of explicit policy? One possible driver is America’s built environment–designed with similar segregationist impulses but not subject to corrective legal action. Zoning and land use policy may inhibit residential mobility which in turns leads to segregated schools. I investigate this drawing on data from over 150 million residential parcels provided by Zillow. I find that school districts whose boundaries include a higher proportion of single-family parcels have a higher proportion of White students and more racial concentration than districts whose boundaries include more mixed types of housing. However, I do not find that districts with more single-family parcels have more racially segregated student populations compared to the larger metro area. These findings help illuminate how land use policy influences educational segregation and contributes to literature on how policies that regulate the built environment affect racial sorting.
