BEA released new local area personal income data today for 2014. San Joaquin County had an above average annual gain. Looking at the breakdown among components and industries, the most notable item is a strong surge in net commuter income, called "adjustment for residence". This is a negative adjustment for places like San Francisco with more jobs than workers, and a positive adjustment for places like SJ County.
Here is the graph for SJ County showing the large gains in 2013 and 2014. A strong piece of evidence that the Bay Area's strong economy is starting to spill over the Altamont pass.
