How many counties does Maine have?
Maine has 16 counties covering 30,843 square miles and roughly 1,328,146 residents. The state was admitted to the Union in 1820 as the 23rd state, and the current county boundaries reflect more than a century of administrative subdivision.
The largest county by land area is Aroostook County at 6,671 square miles, home to about 67,610 residents. The most populous is Cumberland County with approximately 309,364 residents — a density of about 370 people per square mile.
At the other end of the scale, Piscataquis County has only about 21,472 residents.
Maine’s capital is Augusta, while the largest city is Portland — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
