A new look at Illinois’ manufacturing industry over the last decade shows that, since 1999, the state has shed one out of every three jobs. That’s far more severe than the national number of one in 4.

It found that the nation’s manufacturing jobs had decreased not only because of outsourcing to countries with lower labor costs but also because the jobs themselves had become more efficient.
