ABSTRACT
This chapter develops the industry's statistical record of output and employment, by region and by mineral product. The record of output and employment gives some indication of the influence of the location of existing markets and economic activity, of technological change within the mining industries and of the quality of natural endowment resulting from mining activity. The weighting scheme that uses the price of pig iron instead of the price of ore as a weight will be called the "alternative weighting scheme". As we go along, some effort will be made to indicate the effect of using this scheme. No attempt has been made to correct this, since the more defective estimate is probably the estimate for all mineral employment. However, the movements of the weighted averages for the United States reflect shifts among regions and among industries. It is true that, if people looks at single corporation, chance-from their point of view-plays an important part in success or failure.
