(ABC4) – Did you know 20% of American’s claim Irish ancestry? That’s more than 31.5 million residents, according to the U.S. Census Bureau.

Irish heritage is second only to German heritage in the U.S. According to the U.S. Census Bureau, even our presidents largely represent an Irish heritage – exactly half of our presidents, 23, trace some of their roots to Ireland. That includes current President Joe Biden.

These five states have the most residents of Irish descent:

  1. California
  2. New York
  3. Pennsylvania
  4. Florida
  5. Texas

The U.S. Census Bureau reports that while these states have “the most smiling Irish eyes,” none of them have the highest percentage of people with Irish ancestry.

Those fives states are:

  1. New Hampshire: 20.2%
  2. Massachusetts: 19.8%
  3. Rhode Island: 17.6%
  4. Vermont: 17%
  5. Maine: 16.6%
