What drives Rockford’s History grade
On its age, its old homes and the National Register, Rockford is more historic than 68% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

NoteThe founding year comes from Wikipedia alone; no second source gives 1815.
