Industrial distribution of unfair labor practice and representation cases received, fiscal year 1952

p. 296. Nine columns: stub plus All cases, CA/CB/CC/CD (under "Unfair labor practice cases") and RC/RM/RD (under "Representation cases"). Arithmetic checks all pass, which supports the digit readings: every data row's seven case-type cells sum to its "All cases" value; the 21 manufacturing detail rows sum to Manufacturing 10,039; the three Transportation-equipment sub-rows (Aircraft, Ship and boat, Automotive) sum to 656; the four Mining sub-rows sum to 270 column by column; the seven Transportation/communication sub-rows sum to 1,460; and the nine major-division rows sum to Total 15,901. No misprints detected. Capitalisation kept as printed: "Metal Mining" and "Coal Mining" carry a capital M on "Mining" while all neighbouring stub labels are lower-case after the first word. Two readings worth flagging even though both are confirmed by their row sums: Water transportation has CB 58 greater than CA 55 (the only such row), and Products of petroleum and coal has RD 17 against RM 5. Footnote 2 is printed without a closing period. Indentation (major division / detail / sub-detail) is not representable in the flat grid; Transportation equipment and its three sub-rows, and Mining and its four sub-rows, are detail-level groups whose sub-rows are indented one step further in the original.
