North Slope Borough is a borough located largely in the North Slope region of the U.S. state of Alaska. As of the 2010 census, the population was 9,430.[3] The borough seat is Barrow.[4] Since 2011 the mayor is Charlotte Brower.


According to the U.S. Census Bureau, the borough has a total area of 94,796 square miles (245,520 km2), of which 88,695 square miles (229,720 km2) is land and 6,101 square miles (15,800 km2) (6.4%) is water.[5] The borough is larger than 39 states.[6]

Its western coastline is along the Chukchi Sea, while its eastern shores (beyond Point Barrow) are on the Beaufort Sea.

The North Slope Borough is the largest county-level political subdivision in the United States by area, with a larger land area than that of the state of Utah (itself the 13th largest state in the nation). Although the adjacent Yukon-Koyukuk Census Area is larger in area, it has no borough-level government. The borough is also the fourth-least densely populated county-level entity in the United States (the Yukon-Koyukuk Census Area is the least densely populated county-level entity).

Adjacent boroughs and census areas[edit]

It also shares its eastern border with Yukon, Canada, which has no subdivisions.
