|Polygon Attribute Table|
|17||SQKM||Area of the polygon|
|21||ADMSQKM||Area of the admin unit (sum of SQKM)|
|25||CODE||L-Land, IS-Island, IW-Inland Waterbody|
|28||ADMINID||Administrative Unit ID (see below)|
|32||COUNTRY||3-Letter ISO Country ID|
|35||NAME1||Name of first subnational level unit|
|60||NAME2||Name of second subnational level unit ('N.A.' if not available)|
|85||NAME3||Name of third subnational level unit ('N.A.' if not available)|
|110||NAME4||Name of fourth subnational level unit ('N.A.' if not available)|
|135||NAME5||Name of fifth subnational level unit ('N.A.' if not available)|
|160||DEMOFLAG||1 for the major polygon belonging to the admin unit, 0 elsewhere (see below)|

|Arc Attribute Table|
|29||FEATURE||0 - International Boundary
1 - Boundary of first level unit
2 - Boundary of second level unit
3 - Boundary of third level unit
9 - Boundary with "outside polygon"
ADMINID - consisting of
3-digit UN country code + 2-digit first level unit code + 2-digit second level unit code + 2-digit third level unit code + 2-digit fourth level unit code + 2-digit fifth level unit code.
To produce the subnational code, the administrative units were (a) sequentially numbered based on a list of administrativeunits in an official census publication if available, or (b) alphabetically ordered otherwise.
DEMOFLAG - indicates the major (i.e., biggest) polygon in cases where an administrative unit consists of more than one polygon. For all polygons belonging to the same unit, the full attribute information is replicated in the data table. Therefore, for any frequency table construction or summary statistics calculation, one needs to select the polygons with a FLAG value of one first to avoid double counting.
