What drives Middle River’s History grade
On its age, its old homes and the National Register, Middle River is more historic than 35% of U.S. towns, #122 of 261 in Maryland. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

HistoryA character grade: shown, never part of Middle River’s overall grade.
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 Middle River’s 2.5 sits near the middle of its state (56% of Maryland towns have fewer) while its 8 historic buildings outnumber those of 74% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to B−. The pre-1940 share (±0.8 points) is firm at this size. The founding year is the first post office, not a stated founding date.
