HistoryA character grade: shown, never part of Avenue B and C’s overall grade.
Few Arizona towns list much on the Register (a typical Arizona town has 0.1 per 10,000 residents, the U.S. 2.4), so Avenue B and C’s 0.0 sits below most of its state (29% of Arizona 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 (±0.7 points) is firm at this size.
