The Associated Press has compiled a great interactive online tool for viewing unemployment figures for the US. You can view the data by county (Shown above), by state, look at the national averages (Bar chart form), or view results by sector. The data is available back to June 2008 (1 year), and amazingly detailed. I particularly like the county-by-county view where you can zoom into a state and see every individual county with numbers.
