1 The proportions are based on value added and are used to combine both the output and capacity indexes into groupings. The utilization rates 
are calculated by dividing output by capacity, for both individual series and groupings. Total industrial production covers mining, gas and electric 
utilities, and manufacturing. 
2 Primary processing, which incorporates many of the same manufacturing industries that are represented in materials, includes textile mill products; 
industrial chemicals; petroleum products; rubber and plastics products; lumber and products; stone, clay, and glass products; primary metals; and 
fabricated metal products. 
3 Advanced processing includes foods; tobacco products; apparel products; printing and publishing; chemical products such as drugs and toiletries; 
leather and products; furniture and fixtures; machinery; transportation equipment; instruments; miscellaneous manufactures; and government owned 
and operated ordnance facilities. 
4 Other durables includes lumber and products, furniture and fixtures, miscellaneous manufactures, and government owned and operated ordnance 
facilities. 
5 Other nondurables includes tobacco products, apparel products, printing and publishing, and leather and products. 
6 The materials grouping is composed of over 100 materials series found in the index of industrial production. 
7 Grouping includes basic metal materials, consumer durable steel, and equipment steel.
