132 of 132 figures sit in a row or column sum that works out.
p. 113. Decimal points: in the six percent columns many decimal points failed to print/scan, so cells appear as e.g. "100 0", "75 3", "10 6". Every one of these is a one-decimal percentage (neighbouring cells in the same columns show the point clearly, e.g. "4.1", "2.6", "1.0"), so they are transcribed with a decimal point. No digits were changed. Doubtful cell: "Electrical machinery", Unfair labor practice cases / Percent of total. The glyph reads as "4 8" (i.e. 4.8), but 181 of 3,815 is 4.74 percent, which would round to 4.7; the 7/8 distinction is marginal at this scan quality. Transcribed as printed (4.8) without correction. All other column sums and Number = ULP + Representation checks are internally consistent with the printed figures. The footnote begins "1 Source." with what appears to be a period rather than a colon after "Source"; transcribed as it appears. The table has four indentation levels in the stub (Total; major divisions such as Manufacturing and Mining; their component industries; and sub-items under Transportation equipment). Indentation is not preserved in the grid, so e.g. "Aircraft and parts" through "Other" are sub-items of "Transportation equipment", and "Transportation equipment" and "Miscellaneous manufacturing" are components of "Manufacturing". No row in this table is a label-only section line; every row carries values.
