Extending back to 1948, these tables summary quarterly state data on Transfer Payments. The data are seasonally adjusted at annual rates (SAAR)*.

*Seasonal adjustment removes from the time series of the source data the average effect of variations that normally occur at about the same time and in about the same magnitude each year—for example, weather and holidays. After seasonal adjustment, cyclical and other short-term changes in the economy stand out more clearly. Quarterly data reported at annual rates represent values that would be registered if the seasonally adjusted rate of activity measured for a quarter were maintained for a full year.

The most recent and thorough documentation detailing "...almost everything you ever wanted to know" about the Bureau of Economic Analysis state income and employment data is detailed in this report: State Personal Income and Employment: Concepts, Data Sources, and Statistical Methods - September 2014.
