What drives La Salle’s History grade
On its age, its old homes and the National Register, La Salle is more historic than 28% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of La Salle’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 La Salle’s 0.0 sits below most of its state (22% of Colorado 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 C+. The pre-1940 share is a Census survey estimate (±5.2 points). The founding year is the first post office, not a stated founding date.
