Education levels and occupation contribute mightily to salaries, but where a worker lives can give a boost to employees across the board—or result in diminished earnings. It's not just a location's tax rates and cost of living, either. According to a Brookings study, simple geography is responsible for a large variation in earnings: Sebring, Florida, for example, has the low median earning of just $26,000, while the metro area of San Jose-Sunnyvale-Santa Clara in California boasts a median earning figure of $65,000. The same study found that overall workers in the top-earning 30 locations across the U.S. earn an average of 37% more than the workers in the bottom 30 locations.

Silicon Valley boasts a workforce that Sebring, Florida, simply can't. In addition to powerhouse hubs like Silicon Valley, cities in general also boast higher wages for workers than their counterparts living outside of cities. High-paying firms are often located in cities, drawing talent who earn top dollar.
