Cities with the highest Irish ancestry
Which U.S. cities have the highest amounts of Irish ethnicity based on DNA?
To answer this, we averaged the Irish ethnicity of all AncestryDNA customers born in a given city.
In the map below, the darker the green, the higher the average Irish ancestry of the city (bigger circles mean that more AncestryDNA customers were born there). You may not see your city listed because we only looked at the top 50 cities with more than about 400 AncestryDNA customers.
