What drives Lompoc’s History grade
On its age, its old homes and the National Register, Lompoc is more historic than 37% of U.S. towns, #259 of 847 in California. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
C+
HistoryA character grade: shown, never part of Lompoc’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Lompoc’s 0.7 sits above most of its state (73% of California towns have fewer) while its 3 listings outnumber those of 65% 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 (±0.7 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1888 falls in the same era, so the grade doesn’t depend on which one is used.

Before the Spanish conquest, the area around Lompoc was inhabited by the Chumash people. The Original Mission La Purísima was established in 1787 near what is now the southern edge of the city. Purisimeño, a Chumashan language, was spoken in the region during the mission period. After an earthquake destroyed the mission in 1812, it was moved to its present location 1 mile (1.6 km) northeast of the present city. After independence from the Spanish Empire, the First Mexican Empire was established in 1821. The Mexicans secularized the Spanish missions in 1833, and La Purisima Mission fell into ruins.
