What drives Mason’s History grade

A−
HistoryA character grade: shown, never part of Mason’s overall grade.
Few Texas towns list much on the Register (a typical Texas town has 0.0 per 10,000 residents, the U.S. 2.4), so Mason’s 1,006 sits above most of its state (100% of Texas towns have fewer) while its 201 historic buildings outnumber those of 93% 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 (±11.4 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1861 falls in the same era, so the grade doesn’t depend on which one is used.

The first settler is thought to have been Peter S. Parker in 1846. The settlement of Mason grew up around Fort Mason, which was established by the United States War Department as a front-line defense against Kiowa, Lipan Apache, and Comanche, on July 6, 1851. George W. Todd established a Fort Mason post office March 8, 1858, which became consigned to the civilian settlement on June 26, 1858.
