HistoryA character grade: shown, never part of Fairmount’s overall grade.
Founding eraNo founding year we can rely on, so the grade uses the other two–Homes built before 19401.6% of homes (±1.4) · typical CO town 2.5% · U.S. 8.4%C−National Register5 listings, 5.0 per 10,000 residents · typical CO town 1.1 · U.S. 2.4B+

Colorado towns of 2,500+ (159)Ahead of 59%
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 Fairmount’s 5.0 sits near the middle of its state (62% of Colorado towns have fewer) while its 5 listings outnumber those of 70% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±1.4 points) is firm at this size.
