  1. 1 Less than one-tenth of 1 percent.

140 of 140 figures sit in a row or column sum that works out.

Reader’s notes

p. 187. Nine columns. The table has two stacked panels (A and B) sharing one set of column headings, printed only above panel A; panel B's body follows with no headings of its own. The two centered panel titles ("A. COLLECTIVE-BARGAINING ELECTIONS", "B. DECERTIFICATION ELECTIONS") are transcribed as label-only section rows in panel order. Decimal points: this is a coarse 1-bit scan and the decimal point drops out of many percent cells, which print as e.g. "19 8", "9 4", "100 0", "16 0", "4 5". I have restored the point in those cells (giving 19.8, 9.4, 100.0, 16.0, 4.5), on the same principle as closing the space in "8, 044". The restoration is corroborated arithmetically: with these readings every one of the eight percent columns sums to exactly 100.0, and every row satisfies Number of elections = AFL-CIO + Unaffiliated + No representative (all 40 data rows and both Totals check). Footnote-reference cells: in the "Percent of total" column, rows 3,000-3,999, 4,000-4,999 and 10,000 and over carry no value, only a parenthesized raised "1" pointing to the footnote ("Less than one-tenth of 1 percent"). These are written "(^1)" — printed parentheses kept, raised digit marked with the caret. Two printed values in panel B differ by 0.1 from the figure implied by the counts: "20-29"/no-representative Percent prints 14.2 (14/99 = 14.14) and "30-39"/no-representative Percent prints 12.2 (12/99 = 12.12); "400 and over" in the same column prints 3.1 (3/99 = 3.03). These are forced-rounding adjustments by the typesetter, not misreadings — that column sums to exactly 100.0 only with the printed values, so all three are transcribed as printed. Likewise panel A "600-799"/Percent of total prints .7 (30/4,729 = 0.63) and panel B "90-99"/Percent of total prints 2.7 (4/145 = 2.76); both are needed for their columns to total 100.0. A small stray ink mark sits in the gutter between the "Percent of total" and AFL-CIO "Number" columns on the "100-149" row of panel A; it is scanner/press debris, not a value, and no cell content was taken from it. Row-label ranges are printed with en dashes ("1–9"); transcribed with plain hyphens. The union heading is printed "AFL–CIO" with an en dash; transcribed "AFL-CIO". No part of the table is cut off: the caption, both panel titles, all rows and the footnote are inside the crop.
