The boundaries of the North Slope Borough (NSB) encompass 89,000 square miles, stretching from the foothills of Alaska's Brooks Range to the coastline of the Arctic Ocean. NSB is a subdivision of the state of Alaska and provides the local government structure (similar to a county in other states). There are eight communities in this region: Anaktuvuk Pass, Atqasuk, Barrow, Kaktovik, Nuiqsut, Point Hope, Point Lay, and Wainwright. The population of the North Slope is approximately 7,000-most of whom are Inupiat Eskimo.
