HistoryA character grade: shown, never part of Greenwood’s overall grade.
Delaware towns list more on the Register than most of the country (a typical Delaware town has 29.4 per 10,000 residents, the U.S. 2.4), so Greenwood’s 0.0 sits below most of its state (14% of Delaware 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 (±6.7 points). Two sources give 1856.
