HistoryA character grade: shown, never part of Blue Township’s overall grade.
Kansas towns list more on the Register than most of the country (a typical Kansas town has 5.1 per 10,000 residents, the U.S. 2.4), so Blue Township’s 0.0 sits below most of its state (19% of Kansas 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 (±1.8 points) is firm at this size.
