"With most national numbers worsening dramatically in October, the drag on the Michigan economy almost certainly will get more intense over the next several months, particularly given the emerging cutbacks in the Michigan-based auto sector." The Michigan Business Activity Index equally weights nine, seasonally-adjusted coincident indicators of real economic activity. These indicators reflect activity in the construction, manufacturing, and service sectors as well as job growth and consumer outlays. Historical data is available upon request.
