General Notes: **Counties with a "1" are designated as a metro area. Counties marked with a "0" are designated as a nonmetro area. For 2013 metro areas include all counties containing one or more urbanized areas: high-density urban areas containing 50,000 people or more; metro areas also include outlying counties that are economically tied to the central counties, as measured by the share of workers commuting on a daily basis to the central counties. Nonmetro counties are outside the boundaries of metro areas and have no cities with 50,000 residents or more. For year 2004 data metro and nonmetro area definitions are based on the 2003 Metro Classification System.
