Statistical presentationUp
3.1  Data description
Material flow accounts (MFA) provide an aggregate overview of the material flows (in thousand tonnes per year) into and out of national economy. MFA cover solid, liquid and gaseous, materials, except for flows of water and air.

Data on the following flows are compiled and published at national level: domestic extraction (table zp1003rs), imports and exports (table zp1004rs). MFA are used to derive various material flow indicators, for example domestic material consumption (DMC) (table zp1008rs) and resource productivity.

Data on domestic extraction are classified by material categories and the main categories are biomass, metal ores, non-metallic minerals, fossil fuels. Data on imports and exports are compiled broken down by material categories, which are similar as in case of domestic extraction and the main categories are biomass and biomass products, metal ores - raw and processed, non-metallic minerals - raw and processed, fossil fuels - raw and processed and other products. Data on domestic extraction, imports and exports are also available in more detail classification of material categories.
3.2  Classification system
MFA record physical flows of materials broken down by type of flow – e.g. domestic extraction (natural inputs), outputs into environment (residuals), imports and exports (products) and by type of materials. Required material categories/types are specified in a classification of materials which is included in Annex III of t he Regulation (EC) 691/2011 on European environmental economic accounts (section 5 of the annex).

The classification of materials is hierarchical with 4 main material categories. Each main category is further broken down. Breakdown levels of classification of materials are the following: material categories (1-digit code), material classes (2-digit code), material groups (3-digit code) and material sub-groups (4-digit code).
3.3  Sector coverage
MFA are compiled in accordance with the principles of the system of national accounts and include material flows related to activities of all resident units of national economy.
3.4  Statistical concepts and definitions
Main concepts and definitions used in the MFA statistics are presented in the handbook „Systemof Environmental-Economic Accounting 2012, Central Framework“ (international statistical standard for environmental accounts) and in the Eurostat manual „Economy-wide material flow accounts handbook“.

Material flow accounts (MFA) quantify overall demands of the economic system on materials. MFA record the exchange of material flows between national economy and environment (material extraction on input side and waste flows, emissions on output side) and flows between national economy and other economies (foreign trade).

Domestic extraction is the input of materials from the natural environment to be used in the economy. The indicator measures annual amount of raw materials (except for water and air) extracted from the environment per year.

Foreign trade (imports and exports) covers total foreign trade (intra and extra EU trade) and for the purpose of MFA is expressed in mass weight units.

Domestic material consumption
(DMC) monitors total amount of materials, which are directly used within the national economy. The indicator is calculated as domestic material input (domestic extraction plus imports) minus exports.
3.5  Statistical unit
Statistical units differ, depending on the different data sources used for MFA compilation (e.g. agriculture, forestry statistics, geological survey, foreign trade statistics).
3.6  Statistical population
MFA include all material flows (excluding water and air) crossing the system boundaries of the national economy on the input or the output side. Material inputs to the economy cover extraction of natural resources from the natural environment and imports of material products from the rest of the world. On the other side, material outputs include discharge of residuals from economy to the natural environment and exports of material products to the rest of the world. Inter-industry product flows within national economy and natural flows within the environment are excluded from the MFA framework.

System boundaries are: a) between national economy and the environment (material extraction from the environment and discharge of residuals to the environment); b) between the national economy and the rest of the world (imports and exports).
3.7  Reference area
MFA data are available only at national level (the whole area of the SR). Also data for other EU countries and data for total EU are available in the Eurostat public database.

Also additional checks for monitoring potential deviation in time series are performed.
12  Relevance Up
12.1  User needs
Domestic material consumption is one of the global indicators of Agenda 2030, under the goal 12 - Responsible production and consumption. Resource productivity is the key indicator for assessing resource efficiency under Europe 2020 strategy. This indicator is also included in the set of indicators for monitoring of Sustainable Development Goals (SDG).

Main users of MFA data for Slovakia are: European Commission - Directorate-General for Environment (DG ENV), Eurostat, Ministry of the Environment of the SR and mainly its organization Slovak Environmental Agency.


12.2  User satisfaction
Since 2009, the Statistical Office of the SR has carried out at two-year intervals customer satisfaction surveys. The purpose of the survey is to obtain information on user's interest and opinion regarding provision and quality of statistical products and services. Result of the survey in 2017 is published on the website of the Statistical Office of the SR.

However, the customer's satisfaction specifically regarding MFA statistics was not surveyed, only for the whole area of environmental and agricultural statistics.
12.3  Completeness
100% compared to the relevant legislation - Regulation 691/2011 on European environmental economic accounts.

Complete time series for MFA for Slovakia from year 1998 onwards are available in the public database of Statistical Office of the SR and also in the public database of Eurostat.
13  Accuracy and reliabilityUp
13.1  Overall accuracy
Overall accuracy of the MFA statistics is considered very good. Though the MFA is compiled by using a variety of data sources, all of applied sources are official statistics (internal statistics of the Statistical Office of the SR or external statistics of the Ministry of the Environment of the SR and the Ministry of Agriculture and Rural Development of the SR). Compiled MFA are thoroughly checked to prevent errors and verified in the Statistical Office of the SR and also in Eurostat.
13.2  Sampling error
Not applicable for environmental accounts.
13.3  Non-sampling error
Not applicable for environmental accounts.
14  Timeliness and punctualityUp
14.1  Timeliness
Preliminary data on MFA are not disseminated. At national level, the final data are available 12 months after the end of reference year.

Dissemination of data in the public database of Statistical Office of the SR follows the internal schedule. MFA data are published 12 months after the end of reference year. Under the Regulation 691/2011 on European environmental economic accounts, Annex III it is obligatory provide to Eurostat data on MFA within 24 months after the end of the reference year (T-2 years). This means that in 2019 it was mandatory to report data for reference year 2017. Since the MFA data for Slovakia are available earlier as it is specified in the regulation, we report to Eurostat data for T-1 year.
14.2  Punctuality
Deadline for MFA data publication is met in accordance with the schedule.
15  Coherence and comparabilityUp
15.1  Comparability - geographical
MFA are compiled only at the national level (SR). Data for more detail territorial levels of the SR (regions) are not available.

MFA data for all EU countries are published in the Eurostat database. Comparability of data is good, since all countries shall apply common methodology for data compilation according the Eurostat manual.
15.2  Comparability - over time
Published MFA data are comparable in the whole time series, since the same methodology and data sources were used for compilation of the data. Possible changes/revisions in methodology are usually applied in whole time series.
15.3  Coherence - cross domain
Data are coherent with the system of national accounts and satellite system of environmental economic accounts.
15.4  Coherence - internal
Statistical outputs are internally consistent without deviations.
16  Cost and burdenUp
Not applicable. No specific statistical survey for the purpose of obtaining data for MFA is conducted. MFA are compiled by using already existing statistics.
17  Data revisionUp
17.1  Data revision - policy
The revision policy regulates the basics rules and general procedures for revisions of preliminary compiled data and also for revisions due to other reasons. The revision policy and the revision calendar are available on the on the website of the Statistical Office of the SR (only in Slovak).
17.2  Data revision - practice
Published MFA data are final data on which no regular revisions are performed. In case of revisons/corrections of data, the note that data were revised is provided. Possible changes in methodology are communicated after their implementation in the form of methodological notes or footnotes.
18  Statistical processingUp
18.1  Source data
Data compiled in MFA are obtained from variety of data sources - from internal data source of the Statistica Office of the SR: agriculture statistics - data on crop production, foreign trade statistics - data on import and export and also from external data sources: Ministry of the Environment of the SR/State Geological Institute - data on mineral extraction, Ministry of Agriculture and Rural Development of the SR/National Forest Centre - data on logging.

Data on domestic extraction for particular material categories are obtained form the following data sources:
  • agricultural crops (except of nuts and fruits), fodder crops and grazed biomasss - statistical survey of the Statistical Office of the SR on crop production - Pol 18-01,
  • crop residues - estimates by using IT tool developed by Eurostat, estimates are based on data from Pol 18-01 and and Eurostat standard coefficients are applied in calculations,
  • nuts and fruits - estimate of fruit harvest and fruit production carried out by the Ministry of Agriculture and Rural Development of the SR - Odh (MPRV SR) 1-03,
  • wood - statistical survey of the Ministry of Agriculture and Rural Development of the SR on supplies of wood in forestry - Les (MPRV SR) 2-04,
  • hunting - statistical survey of the Ministry of Agriculture and Rural Development of the SR on hunting ground and state of game and game hunting - Polov (MPRV SR) 12-01,
  • minerals - statistical survey of the Ministry of the Environment of the SR on state and changes of reserves of exclusive and non-exclusive minerals - Geo (MŽP SR) 3-01/3a-01.

Source of data on import and export is foreign trade statistics, specifically EXTRASTAT a INTRASTAT system. EXTRASTAT system provides information on exchange of commodities with non-EU countries and it is based on customs declarations. INTRASTAT system contains information on trade in goods with EU Member States as partner countries and data are obtained from statistical surveys -declaration on arrival of goods INTRASTAT 1-12, declaration on dispatch of goods INTRASTAT 2-12.

18.2  Frequency of data collection
Statistical surveys used as data sources for compiling the MFA (mentioned in the item 18.1) have different frequency of data collection:
  • statistical survey on crop production - annual periodicity,
  • statistical survey on supplies of wood in forestry - quarterly periodicity,
  • statistical survey on stock of game and hunting ground, state of game and game hunting - annual periodicity,
  • statistical survey on state and changes of reserves of exclusive and non-exclusive minerals - annual periodicity,
  • declaration on arrival and dispatch of goods (INTRASTAT system) - monthly periodicity.

Data from listed statistical surveys are compiled in MFA on annual basis.

18.3  Data collection
MFA are compiled by using data form already existing internal and external data sources listed in the item 18.1. Data collection for these statistical surveys is conducted according to the Programme of State Statistical Surveys.

No specific survey for the purpose of obtaining data for MFA compilation is carried out.
18.4  Data validation
The source data for the MFA are checked and verified within the process of data collection, on the basis of checks build in the integrated statistical information system. Compiled MFA for Slovakia are thoroughly checked and validated by the Statistical Office of the SR and also by Eurostat. Data checks mainly regarding the plausibility, accuracy, consistency are applied. Also additional checks for monitoring potential deviation in time series are performed.
18.5  Data compilation
The source data collected in the statistical surveys listed in the item 18.1. are compiled into required aggregates for domestic extraction, imports and exports broken down by material categories.
MFA indicators are calculated on the basis of data compiled in MFA (e.g. DMC = domestic extraction plus imports minus exports; resource productivity = ratio of gross domestic product to the DMC etc.).
18.6  Adjustment
No data adjustment.
