The tables in this report generally follow the principles of tabular presentation used by the U.S. Census Bureau in its annual publication, Statistical Abstract of the United States, and described in Bureau of the Census Manual of Tabular Presentation, published by the Bureau in l950. These principles have been accepted by the Department of Business, Economic Development & Tourism for use in its publications and recommended to all other state agencies for official use.
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.
Unit indicators (“In thousands,” “In millions of dollars,” etc.) are usually given as the first element of the headnote. In tables where several units are used, the unit indicators are generally given in the stub or in the column headings.
Footnotes below the bottom rule of tables give information relating to specific items, figures or symbols within the table.
Parallel vertical rules are used to the right of a total column to indicate —
- that the components which follow add to the total;
- in the case of derived figures, that the underlying data are additive to their total.
A dash (-) represents zero in references to absolute values. In rates and percentages, a zero (0) is used. When data are not available (NA) is used. The symbol (X) is used when data are not applicable. A (D) is used when information is withheld by the source to avoid disclosing data for individual companies.
In many tables, details will not add exactly to the totals and subtotals shown because of rounding.
Geographic coverage should be understood as statewide, unless otherwise indicated in the table title, headnote, boxhead, or stub. All annual statistics should be understood as referring to calendar years unless otherwise indicated.
The source of a table may include an address to an Internet webpage. Should the link be invalid, please try the upper levels of the address.
Brackets (< >) indicate the Uniform resource locator (URL) of the website of the publication, title page, if applicable, or the page where cited material appears.
