Data from regional accounts (excluding data for income in the households sector) for the years 2020-2022 have been revised compared to those previously published, following a benchmarking revision in the annual national accounts. The data have been changed due to the necessity of: • implementation of the recommendations of the European Commission (Eurostat), • applying of new and updating existing data sources, including the results of the National Population and Housing Census 2021, • implementation of the guidelines contained in the updated “Manual on Government Deficit and Debt” (MGDD), • maintenance of the continuity and comparability of data series. Description of introduced changes is included in the “Information of the Central Statistical Office on the benchmarking revision in national accounts for the years 1995–2022” of 10 October 2024, available on the website Główny Urząd Statystyczny / Obszary tematyczne / Rachunki narodowe / Roczne rachunki narodowe / Informacja Głównego Urzędu Statystycznego na temat rewizji rachunków narodowych w latach 1995-2022. Additionally, in order to improve estimation methods as well as to enhance quality of result data, data sources applied in the regional accounts calculations have been verified. Macroeconomic categories calculated in the regional accounts are compiled according to the principles of the national accounts system as well as recommendations of the “The European System of Accounts 2010 (ESA 2010)”, introduced by Regulation (EU) No 549/2013 of the European Parliament and of the Council (EU) of 21 May 2013 on the European system of national and regional accounts in the European Union (Official Journal of the EU L 174, 26 June 2013, as amended). Data by kind of activity were calculated in accordance with the Polish Classification of Activities – PKD 2007, compiled on the basis of the Statistical Classification of Economic Activities in the European Community - NACE Rev. 2. The following accounts are compiled in the regional accounts system for each region: the production account and the generation of income account by institutional sectors and kind of activity as well as the allocation of primary income account and the secondary distribution of income account in the households sector. The following categories are calculated for subregions: gross domestic product (GDP) and gross value added (GVA) by kind of activity groups.

For calculations per capita, it was assumed to use the number of population as of 30 June, compiled: for the years 2000-2008 on the basis of the results of the Population and Housing Census 2002, for the years 2009-2019 (in case of indices – for the years 2010-2020) on the basis of the results of the Population and Housing Census 2011, from 2020 (in case of indices – from 2021) on the basis of the results of the Population and Housing Census 2021. For computing per employed person – annual average number of employed persons was applied calculated starting from the year 2020 on the basis of average number of employed persons in the national economy compiled on the basis of 2020 Agricultural Census results. Due to rounding of data, in some cases the sum of the components may be slightly different from total values. Note concerning data in regions’ breakdown (NUTS 2): Comparable data on gross value added per employed person for the years 2000-2001 are missing. Note concerning data in subregions’ breakdown (NUTS 3): Comparable data on gross value added per employed person for the years 2000-2001 are missing.
