31.3 million Americans, or nearly 10% of the population, claim Irish ancestry. This year consumers are estimated to spend $7.2 billion on the green holiday.

Massachusetts is the US state with the second-greatest rate of Irish heritage, according to the study.

Approximately 1,319,826 people, or 18.9%, have Irish heritage in the Bay State, higher than almost every other spot in the country.

North Attleboro and Newburyport also have a high proportion of locals with Irish ancestral roots, with 30.49% and 29.64% of the population in each respective city having Irish ancestors.

New Hampshire holds the top spot as the most Irish state. Nearly 20% of the state’s residents say they have Irish roots.
