Jan 31 (Reuters) - A gauge of manufacturing activity in the U.S. Upper Midwest rose in January to its highest level since August, led by a pickup in production and employment amid concerns about trade and turmoil in Washington, according to a private-sector survey released on Thursday.
Marquette University and the Institute for Supply Management-Milwaukee said their seasonally adjusted index on manufacturing in the Milwaukee region increased to 58.78 this month, the highest level since October. This compared with a reading of 52.87 in December.
A reading above 50 indicates regional factory activity is expanding. (Reporting by Richard Leong Editing by Chizu Nomiyama)
