GDP - State
Bureau of Economic Analysis
A measurement of a state's output; it is the sum of value added from all industries in the state. GDP by state is the state counterpart to the Nation's gross domestic product (GDP). This series was formerly known as gross state product (GSP). Technical notes: There is a discontinuity in the GDP by state time series at 1997, where the data change from SIC industry definitions to NAICS industry definitions. This discontinuity results from many sources, including differences in source data and different estimation methodologies. In addition, the NAICS-based GDP by state estimates are consistent with U.S. gross domestic product (GDP) while the SIC-based GDP by state estimates are consistent with U.S. gross domestic income (GDI). This data discontinuity may affect both the levels and the growth rates of the GDP by state estimates. Users of the GDP by state estimates are strongly cautioned against appending the two data series in an attempt to construct a single time series of GDP by state estimates for 1963 to 2006. Note also NAICS industry detail is based on the 1997 NAICS. SIC industry detail 1987-1997 is based on the 1987 SIC. SIC industry detail 1963 to 1986 is based on the 1972 SIC.
