"Following three months of sharp increases, our Michigan Economic Activity Index paid back some of its gains in April," said Robert Dye, Chief Economist at Comerica Bank. "A downshift in U.S. economic momentum, visible beginning in March, may take a little steam out of auto sales and production over the summer months, but this will not be enough to roll back recent gains to the Michigan economy."

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 2004. Nominal values have been converted to constant dollar values. Index levels are expressed in terms of three-month moving averages.
