"After surging over the second half of last year, our Index has stalled during the first quarter of 2010," said Dana Johnson, Chief Economist at Comerica Bank.  "March, however, marks the first month of employment growth in the Index since August 2007, as well as repeated gains in manufacturing.  As the year progresses, California, like the rest of the nation, should see continued job growth to support a sustained recovery in the private sector."

The California Economic Activity Index equally weights nine, seasonally-adjusted coincident indicators of real economic activity.  These indicators reflect activity in the manufacturing, tourism, travel and trade sectors, as well as job growth and consumer outlays.  The Index levels represent a three-month moving average, used to smooth monthly volatility.  The Index is benchmarked so that 2008 equals 100.  A complete Index history is available upon request.
