About Lompoc

Lompoc was the site of a major railroad accident on 23 December 1930, when Southern Pacific Railroad train #4 collided with a freight train and derailed, killing 22 people. The Lompoc post office opened in 1872. Lompoc incorporated in 1964 to prevent city government from being taken over by the larger adjacent cities of Vandenberg Village (now Vandenberg Air Force Base) and Buellton; it had been known as "South Santa Barbara" for many years prior to incorporation. In 1970, the Census Bureau reported city's population as 91% white; 5% Hispanic or Latino of any race; 2% Asian-American; 1% African-American and 0%. The 2010 United States Census reported that Lompoc had a population of 42,434. The population density was 3,236.
