"Michigan's economy has run nearly flat over the course of 2004, largely reflecting a cut back in vehicle production schedules after the first half of the year," said David Littmann, chief economist at Comerica Bank. "Strong auto sales at year-end suggest an up-trend in the state economy for 2005."

The Michigan Business Activity Index (MBAI) represents 10 different measures of Michigan economic activity compiled monthly by the Economics Department of Comerica Bank. The MBAI is seasonally adjusted, corrected for inflation, and expressed on an index basis with base year 1996 equals 100. The MBAI series has been calculated monthly since 1957 and depicts state economic activity over seven full swings of the U.S. business cycle.
