 B.1 Copper, Iron, and Steel
 Production, 1860-1960


 Increased needs for copper and iron are reflected

in production and consumption figures of those metals.

However, production figures for copper, iron, and steel

reflect not only increased needs of domestic industries,

but also the effects of changing markets and of foreign

trade in ores, finished metals, and final goods.

 As a result of large exports, copper output

increased more rapidly than was needed for domestic

production during the period 1860 and 1930, while after

1940 increased copper production was less than adequate

to meet domestic needs. As such, growth rates of copper

production were higher during the initial period and

lower during the latter period than they otherwise

might have been. Since foreign trade did not exert

as strong an influence on iron, growth rates of iron

production reflect domestic needs more adequately
