HistoryA character grade: shown, never part of Pecos’ overall grade.
New Mexico towns list about as much on the Register as the country (a typical New Mexico town has 2.2 per 10,000 residents, the U.S. 2.4), so Pecos’ 58.1 sits above most of its state (87% of New Mexico towns have fewer) while its 7 historic buildings outnumber those of 73% 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 (±5.5 points). The founding year is the first post office, not a stated founding date.

The story so far
Pecos, in brief
Wikipedia doesn’t have a history of Pecos yet. The photos, dates and memories neighbors add here are how it gets written.
Pecos is a village in San Miguel County, New Mexico, United States. As of the 2020 census, Pecos had a population of 1,392. The village has been shrinking slower than other parts of San Miguel County, partly because Pecos is within commuting distance of Santa Fe. The village is built along the Pecos River, which flows from the north out of the Santa Fe National Forest. Notable locations nearby include Pecos National Historical Park, Glorieta Pass, and Pecos Benedictine Monastery. It is also an entry point for hunting, fishing, hiking and camping in the Pecos Wilderness. The closest metropolitan area is the Santa Fe metropolitan area, approximately 26 miles (42 km) to the west.
Its first post office opened in 1883. Its population held steady between the last two censuses: 1,392 in 2010, 1,392 in 2020.
