Dataset

The Statistical Abstract files are distributed by the US Census Department as Microsoft Excel files. These files have data mixed with notes and references, multiple tables per sheet, and, worst of all, the table headers are not easily matched to their rows and columns.

A few files had extraneous characters in the title. These were corrected to be consistent. A few files have a sheet of crufty gibberish in the first slot. The sheet order was shuffled but no data were changed.

The tables that were changed (this is table 1119):

0166 0257 0362 0429 0445 0446 0459 0461 0462 0464 0465 0466 0467
0469 0479 0480 0481 0482 0483 0484 0485 0486 0487 0559 0628 0629
1144 1227 1231

This dataset consists of a table of 52 rows and 23 columns.

108 represents 108,000,000. Covers principal carriers filing annual reports with Federal Communications Commission

Footnotes

1. Beginning 2001, detailed financial data only filed by regional Bell-operating companies.
   Access lines and calls reported by about 50 reporting companies.

   prior years may not be directly comparable on a one-to-one basis. Includes Virgin
   Islands, and prior to 1991, Puerto Rico.
3. Beginning 1985, the number of carriers dropped due to a change in the reporting threshold
   for carriers from $1 million to $100 million in annual operating revenue.
4. Excludes taxes.
5. After tax deductions.
6. Based on surveys conducted by FCC.
7. Series revised to include all toll revenues: toll, wireless, ILECs,
   incumbent local exchange
   carriers (ILECs) and competitive local exchange carriers (CLECs).
8. Beginning 1991, data are for all U.S. points, and include calls to and from Alaska,
   Hawaii, Puerto Rico, Guam, the U.S. Virgin Islands,
   and offshore U.S. points. Beginning 1991, carriers first started reporting traffic
   to and from Canada and Mexico. Data for Canada and Mexico
   in prior years are staff estimates.
