Spot on, this is my experience as well. A lot of the once-sketchy parts of Berkeley, Oakland, East Palo Alto, etc. have gentrified and become safer since the 70s and 80s. Part of that has been big shifts in racial makeup and socioeconomics. Starting in the mid-late 90s tech began to really dominate Bay Area employment, bringing in a lot of new (well-paid) people and forcing out many others.
