Of 150 metro areas, San Diego is 21st as an intellectual hub, according to WalletHub, which gathers statistics on metro areas and states.
The key criteria for each metro area are highest percentage of high school grads, adults with some college, holders of bachelor's degrees, holders of graduate or professional degrees, and workers with computer, engineering, and science jobs; also, doctors per capita is a factor.
Since the results are based on percentages, the winners are smaller- and medium-sized metro areas with nearby universities.
The most educated city is Ann Arbor, Michigan (home of the University of Michigan). In second and third place are Raleigh and Durham, North Carolina, known as the Research Triangle, and the location of Duke, the University of North Carolina, and North Carolina State. Fourth is Provo, Utah, which has Brigham Young University. Boston, chock-full of top universities, is only tenth because of its large population. San Jose, or Silicon Valley, comes in seventh.
San Diego comes in 21st, just behind Albany, New York.
Of the ten least-educated cities by WalletHub's system, five are in California: Fresno, Bakersfield, Visalia, Modesto, and Salinas. In last place is Beaumont, Texas.
