Series Is Presented Here As Two Variables--(1)--Original Data, 1919-1946 (2)--Original Data, 1933-1955 Data Represent Output From Domestic And Foreign Material Including Secondary Copper Produced At Primary Refineries. North And South America Refers To The United States And Chile Through 1925 And Canada Beginning In 1926. Beginning In 1939 Only U.S. Production Is Covered. Data From October 1924-June 1925 Were Prorated From Quarterly Totals. Published Totals For 1945 And 1946 Have Been Revised To Eliminate 2,140 Tons 9,712 Tons Respectively; These Quantities Cannot Be Allocated To Monthly Figures.

Beginning In 1939, Data Refer Only To The United States. Data Include Export And Domestic Shipments. Data For 1919-1923, Collected By The Copper Export Association, Were Converted By NBER From Pounds To Short Tons. Published Totals For 1945 And 1946 Have Been Revised To Exclude 2,140 Tons And 9,712 Tons Respectively; These Quantities Cannot Be Allocated To Monthly Data.

Series Is Presented Here As Two Variables--(1)--Original Data, 1919-1946 (2)--Original Data, 1933-1955 Figures Represent The Output Of Primary Refineries Including From Duty-Free Imported Raw Material Through 1946; Beginning In 1947, From All Imported Raw Material. The Tariff On Copper Was Suspended During 1947 (See Survey Of Current Business, 1955 Supplement, Footnote 7 To P. 159). This Series Is Believed To Be Comparable To Series 01177 (Refined Copper Shipments).

Series Is Presented Here As Two Variables--(1)--Original Data, 1919-1946 (2)--Original Data, 1933-1955 Data Represent Deliveries To Fabricators Of All Refined Copper Regardless Of Origin, Beginning In 1947; Previously Foreign New Material Is Included Only If Duty Free. Data Include Copper Released From The National Stockpile In Certain Months And Beginning With March 1952 Copper Imported From Nonmembers Of The Copper Institute. Deliveries To The National Stockpile Are Not Included. Beginning In 1947, Figures Include Refined Copper From Dutiable Foreign Material. According To "U.S. Foreign Commerce And Navigation", 1946, Only About Six Percent Of Such Imports Were Dutiable In 1946. During 1947 The Tariff On Copper Was Suspended (See Survey Of Current Business, 1955 Supplement, Note 7 To P. 159); Therefore Figures Before And After 1947 Are Considered Comparable.

The IP proportions (typically shown in the first column of the relevant tables in the G.17 release) are estimates of the industries' relative contributions to overall growth in the following year. For example, the relative importance weight of the motor vehicles and parts industry is about 6 percent. If output in this industry increased 10 percent in a month, then this gain would boost growth in total IP by 6/10 percentage point (0.06 x 10% = 0.6%). NAICS = 331411 Source Code: RIW.G331411.S
