The ISM figures are based on responses from over 400 purchasing and supply executives from 18 industries, which are weighted according to each industry’s contribution to GDP. These data are diffusion indexes where a reading above 50 indicates expansion; below 50 indicates contraction. The ISM Manufacturing PMI is a composite index based on the diffusion indexes of five of the indexes (seasonally adjusted) with equal weights: New Orders, Production, Employment, Supplier Deliveries, and Inventories. The figures from the Institute for Supply Management can be found in Haver’s USECON database; further detail is found in the SURVEYS database. The expectations number is available in Haver’s AS1REPNA database.
