The two pie charts show the changing shares of world production of steel between 1984 and 1994. While there has been little change in total world output, there has been a large shift in the location of the production. The former USSR and Eastern European countries have experienced large declines in production. China and Asia (not including Japan) have experienced tremendous growth. The U.S. is now the fourth largest steel producer in the world behind the European Union, Japan, and China.
