Manufacturers' Shipments, Inventories, and Orders M3...... The M3DATA file includes a separate record (reflecting 12 months of data) for each year (1958 or 1968 to 1993) for each of 7 items: value of shipments, new orders, unfilled orders, 4 inventory figures: total, materials and supplies, work in process, and finished goods. The M3RATIO file has ratios of inventories to shipments and unfilled orders to shipments. There is a break in all inventories series: Data prior to 1982 are book value estimates based on a mix of inventory valuation methods. For 1982 and later, data are valued on a current cost basis. Detailed data lines with an * in the UNPUB field are less reliable than higher level aggregates and are for your internal use, not for publication.
