Sample values in Rhode Island
What our API returned at the Census Bureau's interior point of Rhode Island's 3 largest counties by land area, computed 2026-10-29. One point is not a whole county: values can change within a few hundred meters, so look up your own site. "No data" means the dataset has nothing at that point.
