The Inland Empire is what LA folks sometimes derisively call “the 909” (the area code there). It’s working class, more conservative-leaning in comparison to the rest of LA. I think it’s lower crime. I lived for about a year in Palm Springs and spent some time in this area. Much less pretentious than the ritzy parts of LA (greater metro). Much less crime than in the other parts of LA.
We just call it the desert, LOL. SB County is also home to most of the 1% MC’s. Lots of Vagos, who also seem to be expanding their territory westward towards LA recently
