What drives Carlsbad’s History grade

C+
HistoryA character grade: shown, never part of Carlsbad’s 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 Carlsbad’s 2.8 sits near the middle of its state (63% of New Mexico towns have fewer) while its 9 historic buildings outnumber those of 75% 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 (±1.4 points) is firm at this size. Two sources give 1888.
