The Manufacturing ISM Report On Business® is based on data compiled from purchasing and supply executives nationwide. Survey responses reflect the change, if any, in the current month compared to the previous month. For each of the indicators measured (New Orders, Backlog of Orders, New Export Orders, Imports, Production, Supplier Deliveries, Inventories, Customers’ Inventories, Employment and Prices), the report shows the percentage reporting each response, the net difference between the number of responses in the positive economic direction and the negative economic direction, and the diffusion index. A PMI™ reading above 50 percent indicates that the manufacturing economy is generally expanding; below 50 percent indicates that it is generally declining. This page provides the latest reported value for – United States ISM Purchasing Managers Index (PMI) – plus previous releases, historical high and low, short-term forecast and long-term prediction, economic calendar, survey consensus and news.
