Each neighbor’s History grade, on the same three inputs.
Caledonia is more historic than 74% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
