Sources of Price and Volume Measures in the National Accounts

There is a large variety of indices used to derive constant price estimates. Price indices are used to deflate current price estimates, while volume indices are used to extrapolate constant price estimates and derive an implicit price deflator. Since countries have different kind of information concerning price and volume changes available, only the most commonly used sources are mentioned.

In addition to the above mentioned sources, some countries have a construction factor cost price index, that is used to deflate ‘buildings and construction’.
