These data, the state coincident indexes, which track economic activity for every state in the U.S., are released monthly by the Federal Reserve Bank of Philadelphia. Each state coincident index compiles labor market conditions and real wage data into a single variable representative of the state’s economic activity.1 As of February, seven state coincident indexes have declined over the past month, six posted zero growth, and 37 have increased (15 states are below 3 percent annualized growth). Over the past three months, seven have declined and 43 have increased. See the maps in Chart 1.
