B
HistoryA character grade: shown, never part of Grundy Center’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 Grundy Center’s 7.1 sits near the middle of its state (51% of Iowa towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share is a Census survey estimate (±6.2 points). Two sources give 1877.
