Danville, CA, United States

Danville may boast the title of "safest town in California" for five years running, but don't let that fool you - this affluent suburban enclave has a heavy bureaucratic load and sky-high costs of living. With a population of 42,039 as of the latest census, Danville is one of the wealthiest suburbs in the Bay Area, home to households with a median income of over $223,000. However, the town's long, dry summers and periodic multi-day stretches of no rain, even in winter, can be a persistent headache. Danville is best suited for well-heeled families seeking a tranquil, security-conscious lifestyle, though the red tape and price tag may be too much for many.
