The Federal Reserve reports that output at the nation's factories, mines and utilities edged up 0.2 percent last month. It rose 0.6 percent in July.
Production at factories, the largest single element of industrial production, slowed to 0.2 percent after gaining 0.7 percent in July. Much of softness came from a decline in auto production, which spiked in July. Excluding autos, manufacturing rose 0.5 percent.
Output rose for basic consumer goods such as food, clothing and paper by more than 1.0 percent.
Manufacturing has helped drive economic growth over the past year.
