For Portugal, quarterly national accounts, including the expenditure and production approaches to GDP, nominal and real (i.e., at current and chained prices).
GDP at market prices - the final result of the production activity of resident producer units. Defined three diferent ways as the sum of gross value added of various institutional sectors/industries, the sum of final uses of goods and services by resident institutional units plus exports minus imports of goods and services and the sum of uses in the total economy generation of income account.
Gross value added - (GVA) the balancing item of the production account. Uses output as a resource and intermediate consumption as a use. Valued at basic prices as it does not include taxes less subsides on production.
Gross fixed capital formation - resident producer's acquisitions, less disposals, or fixed assets during a given period plus certain additions to the value of non-produced assets relized by the productive activity of producer or institutional units.
The source uses a volume chain linked procedure for its quarterly national accounts data. This makes data comparable accross multiple years.
Exports are expressed in F.O.B. terms.
Revisions to the quarterly national accounts data occur as part of a regular cycle of data releases and updates. The cycle consists of four main phases:
Provisional data release: Approximately 45 days after the end of the reference quarter, INE releases provisional estimates of the main macroeconomic aggregates (such as GDP, consumption, investment, and exports). These estimates are based on available data at the time, which may be incomplete or subject to revision.
First revision: About 90 days after the end of the reference quarter, INE publishes a first revision of the provisional estimates. This revision incorporates new and updated data sources that were not available at the time of the provisional release. The revision may also include methodological improvements or corrections.
Second revision: Around 150 days after the end of the reference quarter, INE issues a second revision of the quarterly data. This revision may incorporate additional data sources or methodological improvements that were not available at the time of the first revision.
Final data release: Approximately one year after the end of the reference quarter, INE publishes the final estimates of the quarterly national accounts data. These estimates are based on all available data sources and are considered to be the most accurate representation of the economy's performance during the reference period.
It's worth noting that the timing and frequency of revisions may vary depending on the availability and quality of data sources, as well as other factors such as changes in methodology or revisions to past data.
