Todd Township is more historic than 83% 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.
Two places: the Cold Spring Farm (listed 2000) and the Cowans Gap State Park Family Cabin District (1987).
15% of Todd Township’s homes were built before 1940 (Census estimate, ±6.1 points), against a typical 18% for a Pennsylvania town; the median home was built in 1986.
