HistoryA character grade: shown, never part of Monroe’s overall grade.
Iowa towns list more on the Register than most of the country (a typical Iowa town has 9.1 per 10,000 residents, the U.S. 2.4), so Monroe’s 0.0 sits below most of its state (17% of Iowa 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 D to B. The pre-1940 share is a Census survey estimate (±7.3 points). Two sources give 1851.
