|Colonel Robert Rutherford McCormick (1880-1955), was named the President of the Chicago Tribune Company in 1911 and he held this position until his death in 1955.|
In McCormick's time, it referred to the city and its grain, timber, and livestock hinterlands covering parts of five states (Illinois, Indiana, Wisconsin, Michigan, and Iowa), all of which were served by rail delivery of the colonel's newspaper. Later in the century, it came to mean a smaller, denser area of city and suburbs in three states stretching from northern Indiana to southern Wisconsin.

Because Chicago is such a large city on its own, it boasts a much wider metro area than most others in the country, save for New York and Los Angeles. Dating back to 1950, when statistical analysis for metro areas emerged, Chicagoland included the eight collared counties of Cook, DuPage, Will, Lake, McHenry, Kane, Kendall, and Grundy as well as Lake County in Indiana which to many a Chicagoan's surprise physically borders the city. Over the years, due to Chicago's expansion, the definition has also widened to include four more Indiana counties (Porter, LaPorte, Newton, and Jasper) as well as Kenosha County in Wisconsin.
