The Non-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 (Business Activity, New Orders, Backlog of Orders, New Export Orders, Inventory Change, Inventory Sentiment, Imports, Prices, Employment and Supplier Deliveries) this report shows the percentage reporting each response, and the diffusion index. An index reading above 50 percent indicates that the non-manufacturing economy in that index is generally expanding; below 50 percent indicates that it is generally declining. Orders to the service producers make up about 90 percent of the US economy. This page includes a chart with historical data for the United States ISM-Non Manufacturing Business Activity.
