Adak Naval Air Station continued to be a military base during the Cold War but was designated a Base Realignment and Closure (BRAC) site in 1995 and closed in March 1997. Shortly thereafter, the town of Adak was incorporated at the site of the former base. Down from a peak population of 6,000, the island recorded a 2010 census population of 326 residents, all in the city of Adak, in the northern part of the island. In 1980, the Aleutian Islands National Wildlife Refuge was created and much of Adak Island lies within its boundaries.
