HistoryA character grade: shown, never part of Arnold Line’s overall grade.
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 Arnold Line’s 0.0 sits below most of its state (19% of Mississippi 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 (±1.6 points) is firm at this size.
