"Our Michigan Index kept its upward momentum in June after improving in May. Payroll job growth in Michigan increased in May, June and July, breaking out of an ominous stall pattern that extended through the end of 2013 into early 2014. National auto sales were strong through midsummer and that has spurred production increases for Michigan-based assembly plants and suppliers," said Robert Dye, Chief Economist at Comerica Bank. "State sales tax revenues are trending up this year, showing that improved household finances and confidence are being felt at Michigan retailers."

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.
