ESA 2010 implementation and data quality

ESA 2010 implementation

ESA 2010 regulation requires that the Commission reviews its application every five years beginning in 2018 and reports to the European Parliament and the Council. The review evaluates:

(a) the quality of data on national and regional accounts; 
(b) the effectiveness of the regulation and the monitoring process applied to the ESA 2010 and
(c) the progress on contingent liabilities data and on the availability of ESA 2010 data.

ESA 2010 data quality

ESA 2010 data are presented and explained at dedicated webpages: 

Furthermore, the ESA 2010 regulation prescribes that the quality of national and regional accounts data sent in to Eurostat is assessed in terms of relevance, accuracy, timeliness and punctuality, accessibility and clarity, comparability and coherence. The modalities, periodicity and indicators of this assessment process are defined in Commission Implementing Regulation (EU) 2016/2304.

The quality reporting and assessment exercise started in 2017 and is carried out annually. By 15 February, Eurostat provides Member States as well as Iceland, Norway and Switzerland with pre-filled national quality reports containing quantitative indicators and qualitative information. The countries complement the national quality reports and send them back to Eurostat by the end of May. Eurostat assesses the results and prepares and publishes an overall assessment based on the national quality reports and other available information:


ESA 2010 data revisions

Revisions of national accounts are carried out to increase the accuracy of data when data sources provide new information and/or to introduce methodological improvements in the accounts. According to the European Statistics Code of Practice, revisions follow standard, well-established and transparent procedures and advance notice is given on major revisions or changes in methodologies.

Revision policies

To ensure comparability at EU level, national revision policies align to the voluntary recommendations of the PDF icon harmonised European revision policy for national accounts and balance of payments. Good practices to translate the recommendations into specific actions ensuring accurate, reliable, consistent and comparable data are presented in the Practical guidelines for revising ESA 2010 data.

Benchmark revisions are a coordinated major European revision carried out at least once every five years to incorporate new data sources and major changes in international statistical methodology. They ensure a maximum degree of consistency within national accounts: the longest possible time series as well as consistency across Member States and between domains.

Routine revisions are changes in published data which are related to the regular data production process when data published initially are subsequently updated and released according to a publicly available pre-announced release/revision calendar. Eurostat validates and publishes the revised data in line with its release calendar and as soon as they are transmitted by Member States. According to the PDF icon harmonised European revision policy for national accounts and balance of payments, the highest consistency of the accounts at EU level is achieved after the publications in quarter 3.

Revision practice

Eurostat encourages Member States to ensure accuracy, reliability, consistency and comparability of the accounts by planning and implementing data revisions in line with the revision policies. The information below provides overview of the implemented major revisions of national accounts, including information about the coordinated benchmark revisions in 2019.

17 Member States, namely Belgium, Bulgaria, Germany, Estonia, Spain, Italy, Cyprus, Latvia, Lithuania, Hungary, Portugal, Romania, Slovenia, Slovakia, Finland, Sweden and the United Kingdom, as well as Norway carry out coordinated benchmark revisions of national accounts. Eurostat’s  preliminary GDP flash news release of 31 July 2019 pre-announced the revisions. Most of the revised quarterly and annual data are expected to be released by Eurostat from August to October 2019.  For details on publication of benchmark revisions, please see this pdf icon document.


Next coordinated benchmark revisions are anticipated.
