What drives Walsenburg’s History grade

A−
HistoryA character grade: shown, never part of Walsenburg’s overall grade.
Few Colorado towns list much on the Register (a typical Colorado town has 1.1 per 10,000 residents, the U.S. 2.4), so Walsenburg’s 16.3 sits above most of its state (76% of Colorado towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to A. The pre-1940 share is a Census survey estimate (±9.1 points). Two sources give 1859.
