I was wondering about changes in the makeup of the labor force, and how the increase in contractors, temps and part-time might change how we view the headline (U3) unemployment rate, to wit "less is more." That is, incremental increases in the U3 unemployment rate might indicate larger negative impacts than they have in the past.
So I considered U-6, which casts the net much wider in considering unemployment, and far more of the "shadow unemployment." Which led me to the spread between the unadjusted U6 and U3 unemployment rates. Unfortunately, the time series I built is only ten years and captures one previous recession but the difference there is remarkable.
