The Evolving Urban Form: Chicago

New Geography reports:

The city of Chicago, like other historical core cities, had previously been dominant in its metropolitan area. The earliest Census Bureau metropolitan area (“metropolitan district”) estimates from 1900 indicated that more than 90 percent of the region’s population was contained in the city of Chicago. By 1950, the city of Chicago had fallen to 66 percent of the metropolitan area as defined in that year. The city of Chicago now has only 28 percent of the combined statistical area population of 9.7 million

Another great one from Wendell Cox.
