This series represents the contributions of Midwest Region to the Midwest Economy Index (MEI). The Midwest Region contribution specifically focuses on indicators existing only at a regional level. This series is the weighted average of regional variables measuring the growth in nonfarm business activity based on indicators of four broad sectors of the Midwest's economy: 1) manufacturing, 2) construction and mining, 3) services, and 4) consumer spending.

A zero value represents an average contribution to the MEI by the Midwest Region, whereas a positive value indicates that an above-average contribution to MEI; and negative values indicate below-average contribution to MEI.
