(The US rate is 9.1%; in Wayne County -- which has Detroit -- it's 14.6% and in Oscoda County it's 22.3%.)
The feature seems pretty limited so far -- I can't find anything other than the unemployment data from the Bureau of Labor Statistics and population data from the Census -- but the BLS has tons of data on productivity and compensation that would be wonderful to have too. (And I am certainly in favor of having a new place from which to steal graphs and charts.)
