GDP deflator

Implicit deflators are calculated by dividing an aggregate measured in current prices by the same aggregate measured in constant prices. Implicit deflators are named after the aggregate used (Gross Domestic Product in this case). The deflator is calculated from seasonally and calendar adjusted GDP values and rescaled so that 2010 = 100. The ESA 2010 (European System of Accounts) regulation may be referred to for more specific explanations on methodology.
