The Chicago Federal Reserve has an index of economic activity for the region. In September, the index weakened. It stood at a minus 0.81, down from a minus 0.65 in August and a minus 0.90 the previous month.
A reading at zero or above indicates expansion in economic activity. Unfortunately, these readings show that the region is still in a deep recession.
The Chicago Fed uses a three month moving average to smooth out the raw numbers. Using that average, the reading for September was a minus 0.63, and a minus 0.96 in August.
