Mississippi towns list more on the Register than most of the country (a typical Mississippi town has 71.9 per 10,000 residents, the U.S. 2.4), so Decatur’s 5.2 sits near the middle of its state (49% of Mississippi towns have fewer) while its 1 listings outnumber those of 51% 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 (±2.2 points) is firm at this size. The founding year is the first post office, not a stated founding date.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
