Notwithstanding John Mellencamp's paeans to its small-towns, Indiana's reputation as a rural state just isn't that well supported by its demographics. For instance, although Illinois has a population of 13 million people, to Indiana's six, the vast majority of the Illini population is concentrated in the immediate area of Chicago.
Take out Chicago, Aurora, Elgin, Joliet and Waukegan and Illinois' population drops to 5 million people. Take out Indianapolis and its surrounding cities, and the population of Indiana drops only to four-and-a-half million, just half a million less than Illinois.
Now factor back in the greater land area of Illinois (53,000 square miles (again, removing Chicago and its environs from the calculation)) versus that of Indiana (33,000 square miles (not counting Indianapolis or its satellites)) and you get a population density of 95 people per square mile for Illinois versus 136 for Indiana.
