²The 2003 Rural-urban continuum codes classify metropolitan counties (codes 1 through 3) by size of the Metropolitan Statistical Area (MSA), and nonmetropolitan counties (codes 4 through 9) by degree of urbanization and proximity to metro areas. See the Rural-urban continuum codes for precise definitions of each code.

³The 2003 Urban influence codes classify metropolitan counties (codes 1 through 2) by size of the Metropolitan Statistical Area (MSA), and nonmetropolitan counties (codes 3 through 12) by the size of the largest city or town and proximity to metro and micro areas. See the Urban influence codes for precise definitions of each code.
