Gross domestic product by industry

Note to readers: Fourth quarter 2006

The monthly gross domestic product (GDP) by industry data are chained volume estimates with 1997 as their reference year. This means that the estimates for each industry and aggregate are obtained from a chained volume index multiplied by the industry's value added in 1997. For the period 1997 to 2003, the monthly estimates are benchmarked to annually chained Fisher volume indexes of GDP obtained from the constant-price input-output tables. For the period starting with January 2004, the estimates are derived by chaining a fixed-weight Laspeyres volume index to the prior period. The fixed weights are the industry output and input prices of 2003. This makes the monthly GDP by industry estimates more comparable with the expenditure-based GDP data, chained quarterly.
