Notes    
Increases Were Derived From Annual Data On Wire Mileage In The Above Sources. The Figure For The Previous Year Was Subtracted From The Figure For The Year Being Computed. For 1881-1956, The Annual Figures Refer To Wire Mileage In All Systems. They Were Estimated By The American Telephone And Telegraph Company, Except For Four Benchmark Years (1922, 1927, 1932, And 1937) In Which Bureau Of The Census Data Were Used. For The Segment 1956-1963, The Annual Figures Were Derived By Adding Wire Mileage Reported By Bell Telephone Companies And By Independent Companies. Data For The Independent Companies Are Based On Operating Reports Submitted By Each Company To The U.S. Independent Telephone Association. However Not All Such Companies Report. The Data From Bell Telephone Companies Exclude Drop And Block Wire. Because Of Technological Improvements, Increases In Wire Mileage Do Not Completely Indicate The Increase In Telephone Capacity.
