This map shows school year 2022–23 segregation indexes in US public school districts in order to compare US public school districts against each other in terms of racial segregation. It is based on the Mutual Information Index and Atkinson Index (the former using national racial demographic weightings) defined within the 2011 article “Measuring school segregation” by David M. Frankel and Oscar Volij. School enrollment data comes from the Common Core of Data provided by the US National Center for Education Statistics.
