That’s the median income for U.S. households led by an Irish-American, compared with $51,371 for all households.

There are about 34.1 million Americans who claim Irish ancestry, according to a 2012 Census Bureau survey. Irish is the second-most frequently claimed ancestry, after No. 1 German, Census data show.

The states with the biggest share of people claiming Irish descent are concentrated in the Northeast, led by Massachusetts at 22.6 percent and followed by New Hampshire at 21.9 percent and Rhode Island and Delaware at 18.5 percent each. Vermont rounds out the top five, with 18.3 percent of people claiming Irish ancestry.

The most heavily Irish congressional district is Massachusetts’ 8th (33.1 percent), which includes part of Boston and all of Quincy and Brockton. It’s represented by Democrat Stephen Lynch.

The next most-Irish district is Massachusetts’ 6th (27.5 percent), which includes Lynn, Peabody and Salem and is represented by Democrat John Tierney.

President Barack Obama and Vice President Joe Biden met Irish Prime Minister Enda Kenny at the White House last week.

Obama has Irish roots to the town of Moneygall, about 85 miles southwest of Dublin. In 1850, Obama’s great-great-great grandfather on his mother’s side, Falmouth Kearney, sailed for the U.S.

“Now I knew that I had some roots across the Atlantic, but until recently, I could not unequivocally claim that I was one of those Irish-Americans,” Obama said during a visit to Ireland in May 2011.

“But now, if you believe the Corrigan Brothers, there’s no one more Irish than me,” Obama said, referring to an Irish band’s hit, “There’s No One as Irish as Barack O’Bama.”

Happy St. Patrick’s Day from Political Capital.
