Irish-American population: 14.9% Nearly one person in six in and around Rhode Island's capital is of Irish descent, giving rise to all sorts of Celtic-themed clubs, pubs, restaurants and activities. "Providence's Irish contingent is strong enough that I can find lots of people of a like heritage, but not so dominant that I only have Irish friends," says Ned McCrory of the Society of Friendly Sons of St. Patrick's local chapter. McCrory's 113-year-old club is just one of several Providence-area Irish cultural groups. The Museum of Newport Irish History documents the community's experience going back to the 17th century, while the Ceilidhe Club of Rhode Island sponsors concerts and classes in Irish music, knitting, Gaelic and more. There's even an annual "Tour de Patrick" -- a series of three 5-kilometer running races held around St. Patrick's Day.
