Economic activity continued its seesaw pattern of recent months as real gross domestic product edged down 0.1% in May after rising 0.4% in April.

Note to users

The monthly gross domestic product (GDP) by industry data are chained volume estimates with 2002 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 2002. For the 1997 to 2004 period, 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 2005, 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 2004. This makes the monthly GDP by industry estimates more comparable with the expenditure-based GDP data, chained quarterly.


With this release of monthly GDP by industry, revisions have been made back to January 2007.
