What drives Cumberland Township’s History grade

On its age, its old homes and the National Register, Cumberland Township is more historic than 70% of U.S. towns, #474 of 1,035 in Pennsylvania. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Cumberland Township’s 245 sits above most of its state (92% of Pennsylvania towns have fewer) while its 174 historic buildings outnumber those of 92% of U.S. towns.

How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±2.5 points) is firm at this size.
