ROB Manufacturing Data

The ISM Manufacturing Report On Business® is so highly respected because it is based on hard data, not conjecture. The Institute's Business Survey Committee, a group made up of more than 800 purchasing and supply executives from across the country, provides the data. Members of the committee respond confidentially to a monthly questionnaire about changes in production, new orders, new export orders, imports, employment, inventories, prices, lead times, and the timeliness of supplier deliveries in their companies comparing the current month to the previous month. The questionnaire also solicits data on commodities, which are up or down in price and in short supply, and asks for general remarks on business conditions. The responses of the committee members mirror the economic activities of the manufacturing sector, nationally, ensuring a report that accurately represents current business conditions.

Most recent PMI report

Past Month PMI report

In February 1982, the U.S. Department of Commerce (DOC) paired with ISM to develop the PMI®. This index adjusts five components of the Institute's monthly survey—new orders, production, employment and inventories—for normal seasonal variations, adds in supplier deliveries and applies equal weights to calculate them into a single monthly index number, the PMI®.

In January 1989, the Supplier Deliveries Index from the Report became a standard element of the DOC's Bureau of Economic Analysis Index of Leading Economic Indicators. The data was incorporated into the index from June 1976 forward. In January 1996, The Conference Board began compiling this index.
