Of the five largest manufacturing states in the Midwest, Illinois is the only one with significantly more government workers than manufacturing workers. In Indiana, there are 125,000 more manufacturing jobs than government jobs; in Wisconsin, there are 92,000 more manufacturing jobs than government jobs; in Michigan there are 55,000 more manufacturing jobs than government jobs; and in Ohio, government jobs slightly outnumber manufacturing jobs by 17,000.There has to be a research opportunity, identifying total factor productivity by sector. Despite the slow economic recovery, the article notes that Indiana added ninety thousand manufacturing jobs (thus government employed fewer workers at the trough); Wisconsin added fifty thousand (ditto; also this is before the election of Scott Walker, the labor protests, and the recall); Michigan, 171,300 added (you'd think with the automotive relief bill Mrs Clinton could have closed the deal in that state); then Ohio plays catch-up, with about 76,000 manufacturing jobs added.
Chicago Magazine notes that Greater Chicago, and counties with a university presence, are holding their own, but other counties are losing out. The greatest population loss is in Winnebago County, where Rockford is. Might be a research project involving central place theory, with the smaller municipalities, including Rockford and Peoria, losing population while Chicagoland gains.
