What drives St. Clair’s History grade

On its age, its old homes and the National Register, St. Clair is more historic than 57% of U.S. towns, #105 of 247 in Missouri. Its share of homes from before 1940 holds the grade up; its age pulls it down.

All U.S. towns we grade (21,289)Ahead of 57%

Missouri towns of 2,500+ (247)Ahead of 58%

Missouri towns list about as much on the Register as the country (a typical Missouri town has 2.4 per 10,000 residents, the U.S. 2.4), so St. Clair’s 4.2 sits near the middle of its state (60% of Missouri towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share is a Census survey estimate (±10.6 points). Two sources give 1859.
