Economic activity in the manufacturing sector expanded in March but at a slower pace than February, according to the Institute for Supply Management’s purchasing managers index for US manufacturing, released today. March’s index reading was 57.2, down from February’s reading of 57.7, which was the highest since August 2014.

Readings above 50.0 generally indicate expansion.

The employment portion of the index jumped to a reading of 58.9 in March from 54.2 in February.

A resurgence among American manufacturers that began last fall and picked up after the election of Donald Trump carried on in March, MarketWatch reports, with employment rising to the highest level in six years.
