The headline
2,271 US public schools have student bodies in which no single racial or ethnic group exceeds 35% of enrollment, roughly the working definition of "balanced" or "fully integrated" used in school-integration research.
These schools are an exception. Most US public schools are heavily concentrated in a single racial group: 2,351 schools are 95%+ White, 731 are 95%+ Black, and 2,724 are 95%+ Hispanic.
Where the diverse schools are
Schools meeting the no-group-over-35% threshold cluster in a handful of geographies. Military-base schools, where housing is assigned, not chosen. The inner-ring suburbs of major metros that have themselves diversified over the past 30 years (parts of suburban DC, Atlanta, Houston, and Sacramento). And magnet schools with deliberate balanced-enrollment lotteries.
Several major US cities have almost no schools meeting this threshold. Not because the cities themselves are homogeneous, but because attendance zones run through neighborhood-segregated patterns that channel students into single-group schools even when the surrounding metro is diverse.
What the research says
Decades of research, beginning with Coleman in 1966 and continuing through contemporary work by Reardon and others, finds that racially and socioeconomically diverse schools produce measurably better outcomes for low-income students and no detectable harm to higher-income peers. The list of schools that have achieved this composition organically, without busing, is therefore useful both as a research resource and as a parent-decision tool.
Methodology
Source: NCES Common Core of Data 2024-25 race/ethnicity data. We computed the maximum single-group percentage at each school (max of White, Black, Hispanic, Asian, Pacific Islander, Native American, Two-or-more), and selected schools where that maximum is below 35%. Schools with fewer than 200 total students are excluded so the percentages are stable.
