Blank means the geographic field is not applicable for that record type and the data field is empty.

1/Codes: 0 = worked outside the U.S., 1 = worked in central city of metropolitan area, 2 = worked in remainder of metropolitan area, 3 = worked in nonmetropolitan area.

2/See "List of Metropolitan Status/Rank/Size Codes" for documentation of codes.

Note: There is a known tabulation error in the CTPP National Part 2 tables. In record types 5 and 6, a total of 565,990 workers are incorrectly tabulated as working outside metropolitan areas. For record type 5 this makes the number of workers with powmetro code of zero equal to 22,565,015. The correct number is 21,999,025 of which 110,300 work outside the U.S. and 21,888,725 work in nonmetropolitan areas. For record type 6 the erroneous records have a value of 1 (13,490 workers) or 2 (552,500 workers) on powccs_00, in conjunction with a powmetro value of 0. See the file "CTPP National Part 2 Data Error.xls" for an estimate of the error for each powmetro category. The total error shown on that worksheet is slightly less (560,160) because the main CTPP data have been summed from individually rounded metropolitan area data, rather than tallied and rounded once as in the National.
