This series represents the contributions of the manufacturing sector to the Relative Midwest Economy Index (RMEI). his series is a weighted average of state and regional indicators encompassing the entirety of the five states in the Seventh Federal Reserve District (Illinois, Iowa, Iowa, Michigan, and Wisconsin).

The series measures the growth in nonfarm business activity in the Midwest Region based on the Midwest Region.

A zero value represents an average contribution to RMEI by the Midwest Region, a rate historically consistent with the growth of the national economy, whereas positive values indicate above-average relative contribution; and negative values indicate below average relative contribution.
