Macro Trends In Copper Consumption

This paper looks at how changes in the economies and demographics of the eight largest copper-consuming countries have been affecting their consumption of copper. The period of 1976 to 2005 is considered. Annual changes in measures like intensity of use of copper, per capita consumption of copper, copper consumption based on per capita income, and copper consumption from industrial production for each country and in aggregate are calculated. Other factors like the change of industrial production relative to total GDP and population/age trends are also considered for the individual countries. Non-parametric and parametric statistical tests are used to determine the significance of observed trends and relationships for individual countries and in aggregate. The results give insights into how copper consumption is changing for the countries and what economic/demographic factors are driving these changes. These insights provide some guidance about where copper consumption trends are headed in the future.
