In the largest U.S. metropolitan areas, suburban school districts enroll 14.4 million students, far more than the 6 million students enrolled in the same metros' urban districts. In fact, students enrolled in the suburban school districts surrounding the 25 largest metropolitan areas represent roughly 30% of the nation's entire public school enrollment. Suburban growth has occurred alongside the creation of a segregated, metropolitan society through policy, law and practice. Discriminatory loan practices, federal highway construction, site selection for subsidized housing and exclusionary zoning are examples of how racial discrimination permeated to origins suburban society. State and federal governments are dominated politically by those representing suburban constituents too often eager to maintain an exclusionary status quo. As shifting populations change suburban school enrollment, education policy trends formerly confined to urban districts have spread to suburban ones. Many suburban school districts have experienced growth in the charter school sector, as well as a rash of school closures. Suburban schools and districts reflect broader societal problems, paradigms, and possibilities. This paper draws on federal enrollment data from the nation's largest 25 metros from 2011-2020 to descriptively analyze suburban school enrollment and segregation at the school district-level, seeking to understand different district contexts and their relationship to student segregation.
