What drives Hillandale’s History grade

On its age, its old homes and the National Register, Hillandale is more historic than 14% of U.S. towns, #200 of 261 in Maryland. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

Few Maryland towns list much on the Register (a typical Maryland town has 0.9 per 10,000 residents, the U.S. 2.4), so Hillandale’s 0.0 sits below most of its state (20% of Maryland towns have fewer) while its 0 listings outnumber those of 23% 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 is a Census survey estimate (±3.2 points).
