The biggest impact on GDP had the updating of new data sources in:

  • household sector, where the SO SR used the data from administrative data sources for units classified under institutional sector of households. The main aim of using this administrative source was to reduce the burden of reporting units,
  • non-observed economy estimate, where the SO SR clarified the data on the basis of information from supplementary sources and information based on the cooperation with the Financial Administration of the Slovak Republic,

Methodical annotations - Supply and use tables

Supply and use tables (SUT) by commodities and industries in the SR are an integral part of the system of national accounts. The compilation procedure for SUT is based on the „European system of national and regional accounts 2010“ methodology (ESA 2010). Their task is to complete the framework of national accounts system by describing the flows of goods and services in the domectic economy, their exchange with the rest of the world and their use by all resident units during the given period. They are compiled annually to validate the final annual national accounts data at the period of T+36 months.

Formally the supply and use tables have the shape of a matrix. In columns the national version of the Statistical classification of economic activities (SK NACE rev.2) is used, representing the structure of economy by the principal activity of resident units. Commodities defined by the Statistical classification of products by activity (CPA 2015) are shown in the rows.

The supply tables shows the supplies of goods and services distinguishing between domestic output and imports. The output matrix is valued at basic prices. The vector of imports is valued at CIF prices.

The use table showing the use of goods and services consists of three quadrants:

  • The first quadrant is formed by the matrix of intermediate consumption which displays inputs into the production process in the same structure as the supply table.
  • The second quadrant is defined as the final uses and includes the column vectors of the final consumption of households, final consumption of general government and non-profit institutions serving households, gross fixed capital formation, changes in inventories and valuables and exports of goods and services. The use table is valued at purchasers´ prices.
  • The third quadrant is formed by the table showing the value added. It is broken down into compensation of employees, taxes on production, subsidies on production, gross operating surplus, consump¬tion of fixed capital and net operating surplus and mixed income. Data are displayed by industries A*88 of SK NACE Rev.2.

Definitions of indicators in the supply and use tables match with those in the system of national accounts. Commodity flows are expressed in the prices at which the transactions are actually being done. Due to the different valuation of resources and uses, these data must be transformed using the conversion table from the basic into the purchasers´ prices. It contains columns showing trade and transport margins, taxes and subsidies on products and imports taxes. Value added tax is presented in the separate column

The tables are presented in the current prices in thousands of Euros.

Methodical annotations - Symmetric input-output tables

Symmetric input-output tables (SIOT) describe in more detail the production process and transactions with goods and services related to the domestic output and imports. They are based on SUT data, which are transformed from commodity-industry structure into the commodity-commodity structure. Process of transformation from SUT to SIOT is based on the assumption of a product (commodity) technology which means that each product is produced in a specific way, irrespective of the industry where it is produced.

The framework of input-output tables consists of 3 tables:

  • use table for domestic output and imports - at basic prices
  • use table separately for domestic output - at basic prices
  • use table separately for imports - at basic prices

SIOT are compiled every 5 years at the period of T+36 months.

The tables are presented in the current prices in thousands of Euros.

Methodical annotations - Regional Accounts

Revision of regional accounts for the years 1995 - 2017, including the preliminary annual account for 2018

In 2019, the Statistical Office of the SR carried out a large benchmark revision of data in the system of national accounts in the time series since 1995-2017, including the preliminary annual account for year 2018. The aim of the major revision was to incorporate information from updated data sources and methodological clarification the compilation of specific national accounts indicators (see methodological explanatory notes - annual accounts - linking up).
Subsequently, these adjustments of the benchmark revision were incorporated in the individual items of the regional national accounts indicators.

Legend for tables

The methodology for compiling Regional gross domestic product and indicators of regional accounts is based on the European system of national and regional accounts (ESA2010), chapter 13 Regional Accounts.

Gross domestic product (GDP) for the European comparison purpose is expressed in purchasing power parity (Purchasing Power Standard - PPS). Purchasing power standard takes into account the different levels of purchasing power not only exchange coefficient between the national currency and the euro. The basis for the calculation of purchasing power parity is European comparison program (European Comparison Programme - ECP), where the national statistical offices participate on, including SO SR.

Regional Gross domestic product and Regional Accounts indicators are compiled in ESA2010 methodology in accordance with the time series of national accounts for the years 1995 - 2017 including preliminary data of 2018. Data provider for agregate Regional GDP and Regional GDP per capita in PPS is Eurostat (EU 28 = 100 countries belonging to EU). SOSR allocates aggregated regional data to sector level in the structure of NACE Rev. 2. The regional level is determined on the basis of principles based on the NUTS (Nomenclature of The territorial units for statistics - Classification of Territorial Units for Statistics). NUTS 2 level in SR consists from four regions and NUTS 3 area consists from 8 regions.

Definitions

Gross domestic product in market prices is a final result of the production activity of resident producer units created during the current period. Regional GDP is calculated as the sum of values added by industries for each single region, and taxes on products less subsidies on products as a share GVA by region. For international comparison, the Regional Gross domestic product is expressed in purchasing power. Calculation of Purchasing Power Parity (Purchasing Power Standard) is based on prices and sales volumes of goods that are comparable and representative for the countries, which are included in comparison. Purchasing Power Parity eliminates effects of different price levels between countries.

Regional Gross domestic product per capita is a share of two indicators based on different principles - Regional Gross domestic product (in which the criteria by the place of work is considered) and the average number of people residing permanently in the region (based on the principle of residence).

Gross value added at basic prices is calculated as the difference between output at basic prices and intermediate consumption at purchasers' prices. Output consists from products manufactured during the current financial year and intermediate consumption consists of the value of goods and services consumed in the production process as inputs, excluding fixed assets whose consumption is expressed as consumption of fixed capital. The compilation process of Regional Gross value added consists of several steps. Basic approach is based on individual calculation of Gross value added by industry (section NACE Rev.2.) in the single region (NUTS 3). In process of calculation the approach for regionalization is used "bottom - up" and so- called "combined approach ".

Gross fixed capital formation includes the acquisition of fixed assets les s disposals (sales) of fixed assets by producers - residents during a given period. Included are also increases of the value of certain non-produced assets realized by production activity of institutional units. Fixed assets are tangible as well as intangible assets that have been produced as output in manufacturing process and will be used in other production processes repeatedly or continuously for more than one year. Regional Gross capital formation is constructed as the sum of Gross capital formation by industry in the region. Similarly as in case of GVA the approach for regionalization is used "bottom - up" and so- called "combined approach ".

Balance of primary income - net - primary income is characterizing an ability of resident households generate income either as unincorporated enterprises, employees or recipients of property income in the region where households reside or in other regions of the country or outside the country.

Net Disposable income – net disposable income is characterizing the outcome of major transactions relating to the household sector (production activities, distribution and redistribution of income and other transactions) between single regions.

Purchasing power parity

Purchasing power parity (PPP) is an important economic factor that makes it possible to compare the economic power of one country (region) against another country (region) or group of countries (regions). It can also be understood as a price index, which links the price differences of goods and services at a given moment in different countries (regions). It also serves as a criterion for claiming funding for development programs from the EU Structural Funds.

When determining PPP, the so-called Purchasing Power Standard (PPS), is determined as well. PPS is also used as an alternative exchange rate for the currencies of individual countries, taking into account the different price levels of goods and services in those countries. It expresses how many monetary units of a country's currency are needed to purchase a good or service with an average price of 1 Euro. The specific use of PPS for selected countries is shown in the following .Eurostat table.

The obligation of EU member states to provide all necessary data for the needs of the PPP survey follows from the Regulation of the European Parliament and the Council (EC) no. 1445/2007. Binding methodological procedures for determining PPP are described in Eurostat-OECD Methodological Manual on PPP.

Price level comparison

The comparison of price level indices allows a general statement of how "expensive" or "cheap" one country is in relation to another country (group of countries).

A comparison of price level indices (PLI) is calculated for each country as the ratio of purchasing power parity (PPP) to exchange rate (XR) relative to another country or group average (eg EU-27). If the PLI is greater than 100, then the country in question is "more expensive" compared to another country or group of countries; if the PLI is less than 100, that country is "cheaper" compared to another country or group of countries.

Slovakia (through the SOSR) as a member of the EU participates in the European Comparison Program (ECP) through an EU grant funding in the field of economic governance and economic and social performance under European statistics - Single Market Program (SMP-ESS).

More information on Purchasing Power Parity can be found on the Eurostat website in the dedicated section on PPP.

The result is the regular publication of PPP data and up-to-date tables on comparative price levels, which are the responsibility of Eurostat and the OECD. The currently available data is listed below:
