What drives Trenton’s History grade

A
HistoryA character grade: shown, never part of Trenton’s overall grade.
Tennessee towns list more on the Register than most of the country (a typical Tennessee town has 6.1 per 10,000 residents, the U.S. 2.4), so Trenton’s 248 sits above most of its state (97% of Tennessee towns have fewer) while its 103 historic buildings outnumber those of 90% 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 (±6.4 points). The founding year is the first post office, not a stated founding date.
