Overview
Aroostook County, known in French as Comté d'Aroostook, is a large county-level jurisdiction in the U.S. state of Maine. It is organized as a county on the northeastern edge of the state and lies along the Canada–U.S. border. According to the 2010 census, the county had a population of 71,870; its county seat is Houlton, which appears in regional records as Houlton when referenced by name.
Geography and demographics
Aroostook covers a very large area with low population density, featuring forests, rivers and agricultural land. The climate is continental with long winters and a relatively short growing season. Settlement is scattered among small towns and unincorporated townships, and communities often have strong French-Acadian and Franco-American cultural ties.
History and boundary issues
The county's borderlands were the focus of 19th-century tensions between the United States and British North America, culminating in diplomatic agreements that clarified the line. Local memory preserves episodes such as the Aroostook confrontation of the late 1830s, which shaped settlement and cross-border relations.
Economy, land use and culture
Traditional economic activities include commercial agriculture—especially potato production—forestry and related wood products, together with services that support rural communities. Outdoor recreation and wilderness tourism, including destinations such as the Allagash waterways and other conservation areas, contribute to the local economy and identity.
Notable facts and contemporary role
