State GDP Information

Historical State GDP

USgovernmentSpending.com obtains historical State GDP for each of the 50 states and the District of Columbia from the US Department of Commerce, Bureau of Economic Analysis (BEA).

The BEA produces two state GDP series, an SIC-based series up through 1997 and an NAICS series from 1997 through the present. Against the recommendation of BEA, we have spliced the two series together. You can examine the BEA's state GDP data series here. You can see the state GDP series for any state by running a state chart here.

Projected State GDP

USgovernmentSpending.com needs GDP through 2014 in order to allow display and charting of spending as percent of GDP. Obviously, any projection of state GDP is speculative. The estimates of future national GDP, such as those made in the president's federal budget, are notoriously unreliable.

State GDP from 2008 to 2014 is projected by using exactly the same annual change for each state in GDP (and real GDP) as forecast for the national economy in the president's budget in Table 10.1 -- Gross Domestic Product and Deflators Used in the Historical Tables: 1940–201.

The next update to state GDP is June 2, 2009 when BEA will report state GDPs for 2008. USGovernmentSpending.com will replace the current projected numbers for each state with the BEA numbers and then reproject the years 2009 thru 2014 from the new baseline for each state using the national GDP projections from the president's budget.
