The Federal Reserve Bank of Chicago renamed the Chicago Fed Survey of Business Conditions (CFSBC) to the Chicago Fed Survey of Economic Conditions (CFSEC) to better represent the survey’s aim and base of respondents. This change is now reflected in FRED as well.
The goal of the survey remains unchanged: to assess the state of the economy in the Seventh Federal Reserve District, which is served by the Federal Reserve Bank of Chicago. The survey has always been filled out by both business and nonbusiness contacts.
