An amazing 32.3 million or 10 percent of people living in the USA claim Irish heritage. According to the Census Bureau surveys, that’s more than claim to be American (20.1 million)! A whopping 125,840 Irish born people also live in the United States but where exactly do all these Irish and Irish Americans reside?

Not surprisingly, the graphic shows that the largest density of Irish live in the northeast – Vermont, New Hampshire, Maine, Massachusetts, Rhode Island, Connecticut – and then Pennsylvania, all boasting of over 15 percent Irish heritage. It seems that the southern states such as California, Texas and Louisiana miss out with the lowest Irish representation.
