HistoryA character grade: shown, never part of Carson’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 Carson’s 0.0 sits below most of its state (31% of California 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 C−. The pre-1940 share (±0.6 points) is firm at this size.

What stands out about Carson’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
For thousands of years before the arrival of the first Europeans, Tongva Indians lived in the area. Carson lies on part of the Spanish land grant Rancho San Pedro, from the King of Spain in 1784. The Dominguez Rancho Adobe Museum on Alameda Street in Compton (not far from Carson's city limits) is the historic ranch home of the grantees Juan Dominguez and Manuel Dominguez. Carson was named after George Henry Carson, who married a daughter of the Dominguez family in 1857 and managed the rancho.

Carson was so well pleased with Bill’s appearance and excellent social qualifications that he remained for several days the guest of the celebrated buffalo killer and scout.
