In recent years, as a result of the well-known housing crisis in the greater Portland area, many immigrants who choose to remain in southern Maine have moved to cities such as Biddeford, which has a population of 21,452 and is Maine’s sixth-largest city. As of 2018, according to DATA USA, the foreign-born population of Biddeford was 7.35% of the city’s total population. Biddeford, a mill town, became home to many French-Canadian immigrants and their descendents in the early years of the 20th century.
