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 Estancia’s 0.0 sits below most of its state (28% of New Mexico 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 B−. The pre-1940 share is a Census survey estimate (±11.2 points). The founding year is the first post office, not a stated founding date.
