6. Cupertino, Calif.
Home to Apple, this San Jose, Calif., suburb is the only Northern California city to appear in our top 10. This city of 58,302 people can best be described as affluent, and residing there comes at a premium; its cost of living is 90.5 percent above the national average. At the same time, it’s tied for the distinction of being the safest city in our top 10 with a crime rate — 1,283 per 100,000 residents — that’s 59 percent below the national average.
Cupertino’s residents also make a lot; at $120,201, the median household income there is 129.7 percent higher than the national average and 86.5 percent greater than the average Californian household. As with the rest of California, however, the city has larger than average class sizes — 22-to-1 student-teacher ratio compared to the 16-to-1 national average — which, along with the cost of living, kept it out of the top five.
