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. In light of the national and state discussions about immigration, it is helpful to know how many immigrants live in Maine's 16 counties. Maine is 43rd in the nation based on the percentage of their population that is foreign born for 2021. Percent foreign-born by state

What the data show7
Maine's population that is foreign-born has remained completely steady at 3.6% for each of the six different 5-year periods from 2012-2016 to 2017-2021. The most recent population growth in Maine is from out-of-staters moving in, rather than from people from other countries, or from births. 

For 2017-2021, four counties in Maine have 70% of the state's immigrant population. Cumberland County has 37% of the state's foreign-born population, while York has 16% and Penobscot has 9% and Androscoggin 8%. There are six counties where there are less than 1,000 people who are immigrants.

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.
