"Our Michigan Index improved again in June, aided by a strengthening auto sector. Light vehicles sales in the U.S. had a break-out month in June, hitting a 15.9 million unit annual rate and that is good news for Michigan," said Robert Dye, Chief Economist at Comerica Bank. "Statewide employment strengthened in June and sales revenues are trending up. July employment levels were also up, but that is not reflected in our June index."

The Michigan Economic Activity Index consists of seven variables, as follows: nonfarm payrolls, exports, sales tax revenues, hotel occupancy rates, continuing claims for unemployment insurance, building permits, and motor vehicle production.  All data are seasonally adjusted, as necessary, and indexed to a base year of 2008. Nominal values have been converted to constant dollar values. Index levels are expressed in terms of three-month moving averages.
