What is the difference between the Markit Manufacturing PMI and the ISM Manufacturing PMI? The monthly number differs a lot, my understanding is that they are trying to indicate the same thing.

According to en.wikipedia.org/wiki/Purchasing_Managers_Index there are two general providers for the PMI index. The Markit Group and the Institute of Supply Management. The statement is the same but the providers are different and thus the numbers could also differ – Probilitator Mar 4 '14 at 10:47
