Census Area was a census area located in the U.S. state of Alaska. It was part
of the unorganized borough and therefore had no borough seat, although its
largest community was Petersburg. The population was 3,815 at the 2010 census.
It was previously known as the Wrangell-Petersburg Census Area until June 1,
2008, when Wrangell, formerly a part of the census area, was incorporated as a
city-and-borough. The Petersburg Census Area ceased to exist in 2013 when
Petersburg incorporated as a borough, although Kake and several other parts of
the former census area, including Tracy Arm, remain unorganized.
