9. Boston

Per-capita GDP: $60,074

Boston is the capital of Massachusetts as well as the Bay State’s largest city. It’s home to such institutions of higher learning as Harvard, Boston University and Massachusetts Institute of Technology.

The students who attend its schools account for $4.8 billion of the city’s annual economy, according to “Leadership Through Innovation: The History of Boston’s Economy,” a report published by the Boston Redevelopment Authority. Boston is also home to such profitable companies as Liberty Mutual, Gillette and Bain Capital, the former workplace of Republican presidential candidate — and former Massachusetts governor — Mitt Romney.
