ADMINID consistingof
3-digit UN country code +
2-digit first level unit code +
2-digit second level unit code +
2-digit third level unit code
To produce the subnational code, the administrativeunits were
(a) sequentially numbered based on a list of administrativeunits in an official census publication if available, or
(b) alphabetically ordered otherwise.
DEMOFLAG indicates themajor (i.e., biggest) polygon in cases where an administrativeunit consists of more than one polygon. For all polygons belongingto the same unit, the full attribute information is replicatedin the data table. Therefore, for any frequency table constructionor summary statistics calculation, one needs to select the polygonswith a FLAG value of one first to avoid double counting.
