US Unemployment Rate at 9.3% (Chart 1981-May 2010), Michigan, Illinois, California From 1990

I came across this chart of the US Unemployment rate (not seasonally adjusted by the US Bureau of Labor Statistics) from 1981 to May 2010 on Google - public data. I also included Michigan, Illinois and California (from 1990) who have been hit hard. Unemployment could be rolling over from its peak. I'm trying to figure out what the market is saying here.  Are we setting up for a double dip or mild slow down, and how will unemployment react? There might be an issue with loading the flash chart. US 9.3%, Illinois 10%, California 11.9%, Michigan 12.8%.

If the chart doesn't show up for some reason click the photo.
