What drives Clio’s History grade
On its age, its old homes and the National Register, Clio is more historic than 25% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
C
HistoryA character grade: shown, never part of Clio’s overall grade.
Alabama towns list about as much on the Register as the country (a typical Alabama town has 2.7 per 10,000 residents, the U.S. 2.4), so Clio’s 0.0 sits below most of its state (26% of Alabama towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C. The pre-1940 share is a Census survey estimate (±4.4 points). The founding year is the first post office, not a stated founding date.
