Sources and precision

U.S. Census Bureau, 2025 Cartographic Boundary Files. The county outline uses the 1:500,000 file; location maps and interactive overlays use 1:5,000,000. Areas come from ALAND and AWATER, converted to square miles and rounded to one decimal place. Neighbor links are calculated from shared boundary segments, not from point-only contacts. Generalized maps are for geographic reference, not parcel or legal boundary determination. Full methodology.
