This report is one of a series of publications of final data for selected standard metropolitan statistical areas (SMSA's), from the Travel-to-Work Supplement to the Annual Housing Survey (AHS), initiated in 1975 under the sponsorship of the U.S. Department of Transportation (DOT). The AHS is conducted for the U.S. Department of Housing and Urban Development. The data in this report are based on interviews of households in the Chicago SMSA completed during the period from April 1975 through March 1976. Preliminary data from the Travel-to-Work Supplement, covering the first 4 months of the period, were previously published in Series P-23, No. 68, "Selected Characteristics of Travel to Work in 21 Metropolitan Areas: 1975."
