The services PMI was introduced in 1996 by IHS Markitís economists (known as NTC Research at the time) to accompany the existing manufacturing PMI. With the service sector accounting for a larger proportion of GDP than manufacturing for most developed economies, the services PMI was born out of a need for analysts (and in particular central bank policymakers) to better understand changing business conditions in the wider economy. The services PMI has fewer questions than the manufacturing PMI due to some questions, such as inventories, not being relevant to many service providers. Coverage includes financial services, consumer services and all other business services. All services PMI are published by IHS Markit and available to download via subscription.
