Quantity Indexes of U.S. Agricultural Exports and Imports

Excerpts from the report: This report supersedes "Quantity Indexes of U.S. Agricultural Exports and Imports," FAS-M-76, Foreign Agricultural Service, January 1960. It revises the earlier quantity indexes to reflect a more recent base period and to reweight the commodities according to more recent prices. The new base period 1957-59 provides a representative period for agricultural trade relatively free from unusual circumstances. Among other uses, a quantity index provides a quantitative measure of the magnitude of current U.S. trade compared with earlier periods. The indexes, published as a monthly series since 1957, are also adjusted for seasonal variation since 1957.
