Marquette University and the Institute for Supply Management-Milwaukee said their index on manufacturing in the Milwaukee region climbed to 50.36 from December's 48.53.

A reading above 50 indicates regional manufacturing activity is expanding.

The survey's components were mixed versus December's levels.

Gauges on new orders, employment, exports fell, while measures on production and inventories grew.

The survey's six-month outlook on business conditions rose to 69.2 from 66.7 in December.
