I know Southern California is too beautiful; it's seductive.
Reading bits and pieces of history over recent years, I've realized that the weather here has been the driver of SoCal's growth from a very early time.
California's initial growth and statehood came from the Gold Rush and SF's gateway/supply center to it. SoCal was a remote cattle ranching backwater.
The railroad came from SF in 1876, but the second transcontinental railroad went from L.A. through southern Arizona to Texas in 1883, less weather problematic than the first one through Wyoming and over the Sierra. This allowed rich people from the East to visit and they were wowed by the climate, which exists nowhere else in the USA. So they built second homes here, and with refrigerated railroad cars soon started a citrus industry. Florida's citrus industry did not get pushed far enough south to avoid disruptive freezes until after about 1910.
Early 20th century growth industries were aerospace, attracted by the climate, and Hollywood, same plus the varied geographies available within compact distances.
My parents were among countless people who passed through on the way to the Pacific during WWII, noticed the climate just like those wealthy easterners in the 1880's and decided they wanted to live here. For nearly 30 years after WWII it was not that expensive to live here. In one way it was cheap vs. most of the US because both heating and cooling costs are low.
The first real estate price explosion was in the late 1970's. L.A. County population was 2.8 million in 1940, 4.2 million in 1950, 6.0 million in 1960 and 7.0 million in 1970, eased to 7.5 million in 1980. The immigration surge pushed it to 8.9 million in 1990. Growth then slowed and population has been stable near 10 million since 2000.
