The ISM survey is broadly diversified across industries based on the North American Industry Classification System (NAICS), which is weighted by each industry’s share of U.S. gross domestic product (GDP). Survey responses are delineated into 18 industry sectors, such as chemical products, computer and electronic products, and transportation equipment. These responses are raw data, never revised, and not seasonally adjusted since there is no significant seasonal pattern. The ISM Report on Business is compiled monthly by ISM’s Business Survey Committee into an easily understandable, straightforward report. The diffusion index includes the percent of positive responses plus one-half of those responding the same (considered positive).

A purchasing managers’ index (PMI) produced by a company like IHS Markit is an economic indicator representing the rate of expansion or contraction of a specific sector – such as manufacturing, services or construction. Published monthly, PMIs are derived from surveys completed by managers from a range of differently sized companies within a chosen sector. Manufacturing sector purchases tend to react to consumer demand and are often among the first signs of a slowdown. They are also some of the most highly watched economic indicators, because they tend to be the first major surveys released each month.

It represents an early indication of overall manufacturing sector health and trends through the eyes of purchasing managers.
