Industry price indexes (Catalogue no. 62-011-X) are presented here to give an indication of factory gate price movement for those manufacturers who specialize in producing building materials.
These indexes measure changes in shipment selling prices of important commodities sold by major manufacturing establishments. The series calculated for industry indexes are classified under the 1997 North American Industry Classification System (NAICS) whereas those for commodity indexes are classified according to the Principal Commodity Group Aggregates (PCGA) classification.
Prices are for shipments, net (discounts allowed) as of the middle of the month, (f.o.b. plant).
Quality adjustments are made for changes in physical characteristics or terms of sale in order to arrive at estimates of pure price change. No adjustments are made for changes in sales taxes.
Weights, which determine the relative importance of commodities within each index, were derived from the 1997 Input/Output tables.
Price indexes are base-weighted.
Generally, indexes are subject to revisions for six months.
