Guide to Tabular Presentation
XV
The following symbols used in the tables throughout this book, are explained in condensed form
in footnotes to the tables where they appear:
— Represents zero or rounds to less than half the unit of measurement shown.
B Base figure too small to meet statistical standards for reliability of derived figure.
0 Figure withheld to avoid disclosure of information pertaining to a specific organization or
individual.
NA Data not enumerated, tabulated, or otherwise available separately.
NS Percent change irrelevant or insignificant.
S Figure does not meet publication standards for reasons other than that covered by symbol
B, above.
X Figure not applicable because column heading and stub line make an entry impossible,
absurd, or meaningless.
Z Entry would amount to less than half the unit of measure shown.
In many tables, details will not add to the totals shown because of rounding.

Headnotes immediately below table titles provide information important for correct interpretation
or evaluation of the table as a whole or for a major segment of it.
Footnotes below the bottom rule of tables give information relating to specific items or figures
within the table.
Unit indicators (“ tn thousands," “ In millions of dollars,” etc.) are usually given in boldface type as
the first elements of the headnote. In tables where several units are used, the unit indicators are
generally given in the stub or unit column or in the column headings.
Parallel vertical rules are used to the right of a total column to indicate—
(1) that the components which follow add to the total (e.g., tables 1, 4, 29, etc.);
(2) in the case of derived figures, that the underlying data are additive to their total (e.g., table
29 for ratios, table 48 for percentages, table 87 for rates and table 90 for medians).
Heavy vertical rules are used—
(1) in tables where the stub is continued into one or more additional columns across the table
to separate each segment of stub and its accompanying data columns from the continued
segments (e.g., tables 2, 22, 41, etc.);
(2) to set off independent sections of a table (e.g., tables 1, 3, 5, etc.).
