Sources and notes:
Statistics for telephone carriers with over $250,000 annual operating revenues
(large telephone carriers), as well as some other telephone carriers that
voluntarily filed reports.
Based on monthly reports filed with the Interstate Commerce Commission
(ICC), 1916-1933, and the Federal Communications Commission (FCC), 1934-
1943.
FCC Annual Reports to Congress
R 1936: Table XV, pp. 110-1 (includes prior ICC data)
R 1938: Table XXIX, p. 158
R 1939: Table XXX, p. 153
FCC, Statistics of the Communications Industry
S 1942: Table 16, pp. 30-1
For Dec. 1932, 104 carriers reporting monthly to the ICC, and the 91 carriers
reporting to the FCC in 1936 had 86.9% and 83.5% of the Census of 1927
telephone total, respectively. See R 1936: p. 110.
The number of telephone companies reporting varies because of mergers,
acquisitions, and reporting scope changes.
Months where number of telephones likely was affected by a reporting scope
change have "c" in the rc field.

Notes:
Bell System composition clearer and more stable than other systems, and traffic reporting likely more accurate.
Hence Bell System calls per phone likely better quality statistic than industry-wide statistic.
Bell-controlled companies included with Bell System for 1917 and 1922.
Calls are calls originating with the system reporting.
Calls reported are not exact: "they probably do not correctly represent any number
more nearly exact than round billions for the country as a whole, or round millions or tens or
hundreds of millions for individual States." (Census, Telephones, 1922, p. 22)
Telephone traffic varies systematic by day.
"a year's traffic is equivalent to 325 full days' traffic, due allowance being made for the decreased use of the
telephone on Sundays and holidays." (Census, Telephones, 1922, p. 22)
