The unemployment rate for August is 9.7%, a new high for this recession as the economy continues to lose jobs. (Current report is at http://www.bls.gov/news.release/pdf/empsit.pdf, which is not a permanent link.) Alternative measures of unemployment can be found at http://www.bls.gov/news.release/empsit.t12.htm. These measures attempt to add in the effects of discouraged workers and people who are working part time but would like to be working full time. The highest, U-6, which includes both of these groups, is 16.8%.
Update: The teenage unemployment rate rose by 1.7% from the previous month to 25.5% and now is at an all-time high. The rise is consistent with the hypothesis that a rise in the minimum wage will result in job loses for those who have the least skill.
