The Benchmark Input-Output table shows all transactions in millions of dollars. Quantity data is available on products and materials consumed for most manufacturing and mining industries in the Economic Census. Table 3 (“Detailed Statistics”) includes data on electricity consumed by Kwh. Table 6a (“Product Statistics”) shows quantity of shipments by product for selected products, in appropriate units. For example, for NAICS 311211 (Flour milling), the various units displayed are 1000s of sacks (cwt), 1000s of tons, and millions of pounds. Table 7 (“Materials Consumed by Kind) shows quantities of materials consumed for selected products. For example, for the Flour milling industry, quantities of wheat, corn, barley, oats and other grains are shown in millions of bushels. The Energy Information Administration within the Department of Energy also produces much of its energy production and consumption data on a quantity basis. The Bureau of Transportation Statistics produces most of its data on a quantity (ton miles, passenger miles) as well as value basis.
Time series of input-output tables that have been deflated to constant prices should show period to period growth rates similar to what would be measured for quantities. BEA’s annual I-O tables are currently available only in current prices, but research is underway to produce deflated (constant price) tables.
