The Purchasing Manager’s Index for the state climbed again last month, the sixth month in a row the economic indicator has gained ground since a record low score in November. The number is 63.6. A score below 50 indicates a sluggish economy. State Economic Development Director Joe Driskill says this is some evidence the state’s economy is gaining momentum. Driskill is cautious about the news because some other economic indicators, such as the number in the workforce, are still weak. Missouri’s score is above the average for other states in the Midwest and the nation as a whole.
