By diversity index, Hawaii's statewide system is the most diverse large school district in the country, followed by a cluster of Washington, D.C. suburbs. Here is the national ranking of districts enrolling at least 50,000 students.

US public-school enrollment fell about 2.9 percent between 2017-18 and 2024-25, a loss of roughly 1.45 million students. But the national number hides a sharp regional split, with the Northeast and coastal West shrinking while the Sun Belt and Mountain West grow.

Gwinnett County Public Schools ranks 14th of the 89 US districts enrolling at least 50,000 students by diversity index, and no racial group comes close to a majority. But the diversity is uneven school to school, and neighboring Cobb County ranks slightly higher.

Cobb County enrolls about 116,600 public school students across 129 schools, but the county name hides two facts that matter more than any ranking: it holds two separate districts, and its highest-scoring high schools cluster on the east side. Here is what the data actually says.

Wake County, North Carolina runs one of the 15 largest school systems in the country, and it does it as a single countywide district. Here is what the enrollment, demographics, and test-score data say about Raleigh and its fast-growing western suburbs.

We ranked America's public high schools by a Simpson diversity index, and the leaders are not where most people guess. The most diverse high school in the country sits in Anchorage, Alaska, and the rest cluster in Puget Sound, Hawaii, the Las Vegas valley, and Northern California.

Gwinnett County is the largest school district in Georgia and one of the twenty largest in the United States. That fact gets repeated often enough that it stops landing. But when you look at the actual numbers, the scale of what's happening in Gwinnett's classrooms, and how fast the makeup of those classrooms has changed, it's worth slowing down and looking at what the data shows.
