Chicagoland is an informal name for the Chicago metropolitan area. The term Chicagoland has no official definition, and the region is often considered to include areas beyond the corresponding MSA, as well as portions of the greater CSA. Colonel Robert R. McCormick, editor and publisher of the Chicago Tribune, usually gets credit for placing the term in common use. McCormick’s conception of Chicagoland stretched all the way to nearby parts of four states (Indiana, Wisconsin, Michigan, and Iowa). The first usage was in the Tribune’s July 27, 1926 front page headline, “Chicagoland’s Shrines: A Tour of Discoveries”, for an article by reporter James O’Donnell Bennett.
