American Canyon, CA, United States

This sleepy suburban city of 21,837 residents isn't exactly the buzzing metropolis some Americans may have in mind when moving abroad. The median household income is a comfortable $123,935, but the bureaucracy is a persistent headache - the city has an elected mayor, city council, and representatives at the state and federal level. Summers are warm but not scorching, with no average monthly temperatures exceeding 71.6°F. For those seeking a quiet, affordable Californian enclave, American Canyon could be a good fit. But for the city-loving expat, this may be a bit too laid-back.
