Economists estimate that the gauge of manufacturing and overall business activity in the region fell to 54 from 56.2 in October, according to Bloomberg.

"The index has been quite choppy since the trough in February, but the overall trend does look to be positive, suggesting modestly accelerating growth. While this is down notably from the average level of 60 in the prior 1.5 years ending January, the upward trajectory contrasts with contractionary readings from other regional surveys, suggesting that the Chicagoland area has been much more resilient in the face of trade and commodity headwinds."
