The Chicago Business Barometer, also known as the Chicago Purchasing Manager’s Index, is similar to the national ISM Manufacturing indicator but at a regional level and is seen by many as an indicator of the larger US economy. It is a composite diffusion indicator, made up of production, new orders, order backlogs, employment, and supplier deliveries compiled through surveys. Values above 50.0 indicate expanding manufacturing activity.
