> We find that, on average, the 17 U.S. states with the highest union densities:
> have state minimum wages that are on average 19% higher than the national average and 40% higher than those in low-union-density states
> have median annual incomes $6,000 higher than the national average
> have higher-than-average unemployment insurance recipiency rates (that is, a higher share of those who are unemployed actually receive unemployment insurance)
