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 Bloomfield’s 212 sits above most of its state (93% of Iowa towns have fewer) while its 58 historic buildings outnumber those of 86% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share is a Census survey estimate (±7.9 points). The founding year is the first post office, not a stated founding date.
