The U.S. student population is more diverse, but schools are still highly segregated

The U.S. student body is more diverse than ever before. Nevertheless, public schools remain highly segregated along racial, ethnic and socioeconomic lines.

That's according to a report released Thursday by the U.S. Government Accountability Office (GAO). More than a third of students (about 18.5 million of them) attended a predominantly same-race/ethnicity school during the 2020-21 school year, the report finds. And 14% of students attended schools where almost all of the student body was of a single race/ethnicity.

The report is a follow up to a 2016 GAO investigation on racial disparity in K-12 schools. That initial report painted a slightly worse picture, but findings from the new report are still concerning, says Jackie Nowicki, the director of K-12 education at the GAO and lead author of the report.
