Why This Indicator Matters
Maine has the oldest median age in the United States, so drawing in new residents from other states and other countries is important for the economy. Maine is 45th in the nation based on the percentage of their population that is foreign born for 2023. Percent foreign-born by state

Notes
In the census, the term "foreign born" refers to people residing in the United States at the time of the population survey who were not U.S. citizens at birth. The foreign-born population includes naturalized U.S. citizens, lawful permanent immigrants (or green-card holders), refugees and asylees, certain legal non-immigrants (including those on student, work, or some other temporary visas), and persons residing in the country without authorization.
