St. Patrick’s Day is approaching.
For some, that means parades, corned beef, and avoiding being pinched. However, for others it’s more than just a fun holiday: It’s a day to honor their heritage.
While 4.9 million people call Ireland home, 32 million Americans identify as Irish.
That’s right, America is home to more Irish-Americans than Ireland is home to Irish. However, some states are far more Irish than others.
To find the states where St. Patrick’s Day isn’t just a day on the calendar but a true event, we found the states where the most residents are of Irish descent.
How We Determined This
To find the most Irish states, we turned to U.S. Census Ancestry data.
From there, we simply divided the total number of residents with Irish ancestry by the total number of residents. The higher percentage of Irish residents, the more Irish the state.
This data is self-reported, which relies on people accurately knowing their own heritage. Considering that 21% of Americans are unable to name a single great-grandparent, chances are good these results are skewed.
So we can’t guarantee there aren’t a lot of unaware Irish folks out in the Southwest, or that people in areas with a robust Irish population don’t incorrectly assume they are also Irish.
For the cities, we did a similar process, looking at cities and metro areas with more than 25,000 residents.
1. New Hampshire
Percent Irish: 20.2%
Number of Irish residents: 272,613
New Hampshire is the most Irish state in the whole country.
An impressive 20.2% of folks in New Hampshire claim Irish ancestry. That means 1 in 5 New Hampshire residents hail from the Emerald Isle.
Percent Irish: 20%
Number of Irish residents: 1,354,176
While Massachusetts has lost its spot as the No. 1 most Irish state, the state is still pretty Irish.
Don’t believe me? Go to Boston on St. Patrick’s Day. Between the bars full of cheery Irish patrons and the legendary parade, it’s easy to see Massachusetts is Irish and proud.
3. Rhode Island
Percent Irish: 18%
Number of Irish residents: 186,040
Kiss Rhode Island, because it’s pretty Irish. Fully 18% of Rhode Islanders claim to have Irish ancestors on their family tree.
