Today, the Federal Reserve Bank of Chicago released December 2015 figures for its Midwest Economy Index (MEI). The MEI is a weighted average of 129 indicators designed to measure non-farm business activity in the Midwest (IL, IN, MI, WI, IA).

The overall MEI moved up to -0.15 in December from -0.20 in November. A negative MEI indicates that the Midwest economy grew at a slower rate in December than would typically be suggested by its historic growth rate.

The relative MEI increased to +0.28 in December from +0.08 in November. The positive relative MEI index value indicates that Midwest economic growth was higher than the growth rate of the national economy.

Michigan and Indiana were the only states to make positive overall contributions to the MEI, led primarily by Michigan’s manufacturing contribution of +0.03 and services contribution of +0.02. Negative manufacturing contributions from Iowa (-0.13), Illinois (-0.07) and Wisconsin (-0.04) had the greatest impact on the overall MEI’s negative value. All states made positive consumer spending contributions.

The following chart illustrates contributions to the MEI by sector for Illinois and the Midwest as a whole.

The following chart illustrates five-year trend lines for the MEI and Relative MEI indexes. The MEI captures both national and regional factors driving Midwest growth and the relative MEI provides a picture of Midwest growth conditions relative to those of the nation.
