On 18 October 2007, the Census and Statistics Department released for the first time the chain volume measures of GDP to replace the previous constant price series.  This is to gear with the latest international statistical guidelines on the compilation of the volume measures of GDP in order to provide a better measure of the real growth of the aggregate economic activity of an economy.

Under the new calculation method, the volume measure of GDP for each year is compiled by aggregating the volume estimates of its components using the price structure in the preceding year as weights.  Compared with the previous constant price approach where the price weights for aggregating the volume estimates of the GDP components are only updated once every several years, the new calculation method of chain volume measure updates the price weights every year, thus providing a better measure of the growth of GDP in real terms.

The following documents provide further information on this latest statistical development.
