Excerpt from United States Census of Mineral Industries, 1954, Vol. 1: Summary and Industry Statistics; Employment, Payroll, Capital Expenditures, Value Added, Power Equipment, and Related Statistics by Industry; Quantity and Value of Individual Supplies and Products The 1954 Census of Mineral Industries covered establishments meeting the value criteria whether or not they had employees. The mailing lists available for establishments with no employ ees, such as establishments for which all labor was furnished by proprietors or contractors, were somewhat less complete than for those with employees. However, it is believed that in most areas such establishments were included where they met the specified criteria. Specific limitations in such coverage are discussed in the separate industry texts.
