1. County Equivalents include Independent Cities in MD, MO, NV and VA; Boroughs or Census Areas in AK; Parishes in LA; DC treated as State and County.
2. Counties are the primary legal subdivisions of a state. In the New England states they perform few, if any, governmental functions.
3. In some states (CT, RI) they are recognized as historic geographic areas for statistical purposes only.
4. The FIPS Code is the Federal Information Processing Standards code; 3 digit county code unique within the state, 2 digit state code unique within the nation.
5. The Polidata CyAbb is an abbreviation used primarily on our maps. The Cy Seq is a sequential count of county units within the state. Asterisk indicates a break in sequence.

1. Areas/Markets are county-based regions comprised of whole counties or equivalents. This includes Parishes (LA), Independent Cities (MD,MO,NV,VA) Boroughs (AK), and Census Areas (AK).
2. Metropolitan Statistical Areas (MSAs) reflect federal statistical areas. Some counties are not assigned. MSAs are contiguous yet may cross state borders. NECMAs are used in New England.
3. Designated Market Areas (DMAs) reflect television media markets. All counties are assigned to one DMA (a few counties are actually split). DMAs may be noncontiguous and may cross state borders.
4. Internal State Regions (ISRs) reflect geographic regions based largely upon travel regions. All counties are assigned. ISRs are contiguous and internal to state borders.
5. Metro Groups (GMRs) reflect the size and nature of metropolitan counties. They are based upon work done by Dr. Gary Maloney in 1997 and updated/modified/expanded by Polidata.
6. Codes are assigned by either OMB, Nielsen or Polidata to be unique within the nation. Counties unassigned to a metro area are grouped together for consistency purposes.
