Gross domestic product (GDP) at market prices is the final result of the production activity of resident producer units (ESA 1995, 8.89). It is defined as the value of all goods and services produced less the value of any goods or services used in their creation.Data are calculated as chain-linked volumes (i.e. data at previous year's prices, linked over the years via appropriate growth rates). Growth rates with respect to the previous quarter (Q/Q-1) are calculated from calendar and seasonally adjusted figures while growth rates with respect to the same quarter of the previous year (Q/Q-4) are calculated from raw data.
