State unemployment levels for 2012 have been revised, in some cases significantly.
For example, August's unemployment rate, initially reported at 7.8 percent and what would have been the highest level since January 2011, has been changed to 7 percent. After revisions, the highest level of unemployment for 2012 came in January, at 7.2 percent.
Dan Robinson is chief of research and analysis for the state labor department.
He says the department did not believe there was something going on related to Alaska's economy when the unemployment levels went up last summer. He said he and others felt there was instead an issue with the data.
He says he's fairly sure the new rates are more accurate, because more information has come in.
Revisions are done at the federal level.
