Summary: The Demographia City Sector Model classifies the nearly 9,000 zip code tabulation areas (ZCTA's) in the 52 major metropolitan areas of the United States, using urban form, density and travel behavior characteristics and residence age. Major metropolitan areas have more than 1,000,000 residents.

Classifications: There are four functional classifications, (1) the urban core, (2) earlier suburbs, (3) later suburbs and (4) exurbs (outside the urban area and all areas with fewer than 250 residents per square mile (97 per square kilometer). The urban cores have higher densities (7,500 per square mile or 2,896 per square kilometer), and substantially greater reliance on transit, walking and cycling (20 percent or more) than other parts of metropolitan areas. The urban core also includes all non-exurban ZCTA's with a median house construction date of 1945 or before (see page 2).

Replicating the Pre-Auto Suburban City: The City Sector Model criteria produces geographies functionally similar to the urban cores that preceded the great automobile oriented suburbanization that developed after World War II. Exurban areas are beyond the built up urban areas. The suburban areas constitute the balance of the major metropolitan areas. Earlier suburbs include areas with a median house construction date before 1980. Later suburban areas have later median house construction dates.
