| Data description | Input Output Tables(IOT) describe by product and industry the production processes and the transactions in products of the economy with great detail. They are elaborated and improved in compliance with internationally adopted methodological principles and standards of the European System of National and Regional Accounts(ESA'95, before 2010 and ESA'2010 from 2010 onwards - Eurostat edition) and of the System of National Accounts,(SNA'93, before 2010 and SNA'2008 from 2010 onwards) - a colaboration of the UN, OECD, Eurostat, IMF and the World Bank. SUT are based on the concepts and definitions for treating the transactions, the economic individuals and the classificatory principles of statistical units' grouping as they are applied in elsewhere in the System. |
|---|
| Classification system | The European System of Accounts (ESA) 2010 is based on Nace Rev 2. The data refers to years 2010 onwards with the ESA 2010 methodology. Input-Output tables distinguish 64 industries . Data before 2010 are available under ESA1995 . |

| Statistical concepts and definitions | The symmetric input-output tables are recorded in intervals of five years.A symmetric input-output table is a product-by-product or industry-by-industry matrix describing the domestic production processes and the transactions in products of the national economy in great detail. A symmetric input-output table rearranges both supply and use in a single table with identical classification of products (or industries respectively) employed for both rows and columns. The ESA 1995(Regulation 2223/96 of the European Council) for the IOT before 2010 and ESA 2010(Regulation(EU) 549/2013 of the European Parliament and of the Council) for the tables from 2010 onwards may be referred to for specific explanations concerning contents of the tables. |
