Census tracts are small, relatively permanent statistical subdivisions of a county designed by the U.S. Census Bureau to contain roughly 1,200 to 8,000 residents, with boundaries held stable across decades so researchers can track neighborhoods over time. Tract-level figures from the American Community Survey are five-year rolling averages rather than snapshots — that smoothing reduces year-to-year noise in small areas but also means the numbers you see here describe the period ending in the reference year rather than a single moment. For context, we link back to the parent city and state pages where you can compare this tract against its neighbors.
