The largest city in New England, Boston is an educational, governmental, and financial center and a leading fishing and commercial port. Its industries include publishing, food processing, and varied manufactures. High-technology research and development and computer and electronic manufacturing industries have flourished in the area, especially in the corridor along Boston's older peripheral highway (Routes 128 and 95). Tourism, much of it attracted by historic sites and cultural assets, has become increasingly important. Redevelopment in "the Hub" since the 1960s has focused on the Back Bay, where the John Hancock and Prudential buildings are New England's tallest, and on the city's compact downtown on the Shawmut Peninsula, where financial and other offices have been developed since the 1970s. Less than one fifth of the metropolitan area's residents, however, live in the city.
