The Philly Fed's survey this month of the region's manufacturers shows slight increases in business activity - a swing from a negative reading in February.
The closely watched Business Outlook Survey from the Federal Reserve Bank of Philadelphia for March showed notable increases for general business activity and new orders, the bank said.
The survey's broadest measure of manufacturing conditions increased from a reading of minus 12.5 in February to 2.0 this month. A reading above zero indicates growth. The bank said 75 firms in eastern Pennsylvania, South Jersey and Delaware responded to the survey.
