Purchasing Managers' Index

The Purchasing Managers Index, or PMI, is a family of economic indicators derived from monthly surveys of private sector companies that track business conditions such as output, new orders, employment, and supplier delivery times. Purchasing managers are polled each month with simple questions about whether conditions have improved, worsened, or stayed the same, with data collected in the second half of the month aiming for roughly an 80 percent response rate. A reading of 50.0 means the surveyed variable is unchanged from the prior month, a reading above 50.0 indicates improvement or expansion, and a reading below 50.0 indicates decline or contraction. S&P Global and the Institute for Supply Management are the principal producers, together with the Singapore Institute of Purchasing and Materials Management and national bodies such as Swedbank in Sweden and the National Bureau of Statistics in China, collectively covering more than thirty countries.
