p. 95. Seven columns: stub plus Number/Percent of total pairs for All cases, Unfair labor practice cases, and Representation cases. The stub heading carries footnote marker 1 ("Industrial group^1"). The body is unnumbered but indentation marks hierarchy: Manufacturing, Agriculture and forestry, Mining, Construction, Wholesale trade, Retail trade, Finance insurance and real estate, Transportation communication and other public utilities, and Services are major groups; the indented lines under Manufacturing, under Transportation equipment (itself a Manufacturing subgroup with its own indented detail), under Mining and under Transportation/communication are their components. No separate section-label rows are printed. Arithmetic checks all pass as transcribed: in every row the Unfair labor practice Number plus the Representation Number equals the All cases Number, and the nine major-group Numbers sum to the printed Total of 9,543. No misprints detected. Doubtful cells, all read as given with moderate-to-good certainty: Mining, "Unfair labor practice cases / Percent of total" — the glyphs are smudged in the scan and read 2.9, which is consistent with 100/3,403; "Other transportation", "Unfair labor practice cases / Percent of total" — a stray ink speck precedes the decimal point, printed as "..5", transcribed as .5. Percentages below 1 are printed without a leading zero (e.g. ".3") and are kept that way. Values in the 1,000s are printed with a space after the comma in the scan ("9, 543", "1, 512", "1, 039", "1, 146", "7, 560", "2, 729", "4, 831", "3, 403", "6, 140") and have been closed up per instruction.
