More historic than 80% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Rocky Ford is more historic than 80% of U.S. towns, #5 of 159 in Colorado. Its share of homes from before 1940 holds the grade up; its age pulls it down.
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 Rocky Ford’s 26.2 sits above most of its state (82% of Colorado towns have fewer) while its 10 historic buildings outnumber those of 76% of U.S. towns.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.
