11.1. Quality assurance
The Quality policy is defined and publicly accessible in the Quality Declaration and Quality Policy documents. The Quality Declaration expresses the basic ideas and commitments of the President and top management of the SOSR for the Quality Policy as well as increasing efficiency and effectiveness of the integrated management system of the SOSR.
Quality policy is based on the mission of the Statistical Office of the Slovak Republic: to provide high quality and objective statistical products and services by keeping confidentiality of statistical data and by minimising burden on interested parties using effectively existing resources with the aim to support improvement of the information and intellectual capital of our customers. In this way we want to contribute to reduce risks and improve effectiveness in their decision making processes and so to support the sustainable development of the Slovak Republic as the part of EU.
The Quality manual describes the documented procedures of the quality system that are used for implementation and continuous improvement of the quality management system in SOSR. It contains a description of the quality management system and the fulfillment of requirements ISO 9001 standards. Application of the manual in practice ensures that all activities that have an impact on the quality of the products created are planned, managed, reviewed, evaluated and meet requirements. The Quality manual is available only in Slovak version.
The European Statistics Code of Practice is the basis of the common quality framework of the European Statistical System. It is a self-regulatory tool and it is based on 16 Principles covering the institutional environment, statistical processes and statistical outputs. A set of indicators of best practices and standards for each of the Principles provides guidelines and benchmarks for reviewing the implementation of the Code of Practice, thus increasing transparency within the European Statistical System.
European Statistics Code of Practice
11.2. Quality management - assessment
Coverage, reference period, data collection, control and data processing are in line with the Eurostat methodological guidelines. The data collection process is conducted in the Integrated statistical information system called ISIS. SOSR creates technical projects of the statistical surveys describing data collection and its evaluation, including a description of statistical controls and algorithms within the integrated ISIS. The data collection process is ensured by the regional offices of the SOSR during the phase of electronic data collection, ensure using statistical controls and algorithms the data collection process itself. Data validation is done during the data collection, processing and validation of relevant data by the SOSR experts. A data comparison is done with previous periods. Statistics are available in the system to evaluate the quality of the completed questionnaires, the number of questionnaires with errors or outliers, the number of reminders etc. SOSR also performs internal methodical audits. Evaluation of statistical surveys and methodological audits including the analysis of the results are integrated into the existing quality management system.
STS compliance assessment is carried out by Eurostat. Concerning the results of particular data production processes, the overall quality of the indicators is considered to be as good.
12.1. Relevance - User Needs
The requirement to conduct consultations with users of statistical information is stipulated in the Act on State Statistics itself. Consultations during the preparation of state statistical surveys take place within the framework of the preparation of the Program of State Statistical Surveys (PSSZ). PSSZ is a generally binding legal regulation compiled by the SOSR in collaboration with ministries, other central authorities and state organizations and contains statistical surveys organized and carried out by the SOSR, ministries, other central authorities and state organizations. SOSR publishes the Program of state statistical surveys by decree in the Collection of Laws of the Slovak Republic. The Coordinating Council for State Statistics ensures the fulfilment of the tasks of the SOSR. Key users of specific statistical products are listed in the Marketing Plan, e.g. international organizations - Eurostat, OECD, UN and national institutions, e.g. National Bank of Slovakia, etc.
12.2. Relevance - User Satisfaction
Since the 2009, SOSR carries out satisfaction surveys of customers with their products and services at two-year intervals. The goal of surveys is to determine customer satisfaction with the products and services of the SOSR, to obtain information about users, their interest and opinion on provision and quality of statistical products and services. The facts obtained are a valuable resource for the direction of other activities of the SOSR. One of the main goals defined in the Development Strategy. The goal of the SOSR until 2022 is to systematically increase the value of the institution and its recognition at the national and international level. The office also monitors the fulfilment of the stated goal with the help of indicators of the credibility of the SOSR and the rate of use of the information provided by the public.
SOSR conducts credibility surveys through an external independent organization once every 2 years, with the intention of ensuring the objectivity and indisputability of the results from public view.
The credibility survey and the satisfaction survey are only available in Slovak version.
12.3. Completeness
Time series of indicators in accordance with the regulation are available from January 2000 in Datacube and historical time series in SLOVSTAT.
13.1. Accuracy - overall
Overall accuracy is considered very good. SOSR makes great efforts to prevent the occurrence of errors in the data and performs data verification to detect the errors. Most errors are directly consulted at regional offices with the reporting units.
13.2. Sampling error
Sampling errors are monitored during data processing.
The base data for absolute figures of indicator are surveyed:
- By cut-off census of enterprises with 20 and more employees registered in the business register and enterprises in the business register with less than 20 employees that are statistically important (the decision about including them into survey of was done by experts of particular activities or have a turnover in excess of EUR 5 million.
- stratified random survey of small enterprises with less than 20 employees and
- estimation of small entrepreneurs from administrative sources

13.3. Non-sampling error
The technical project of data processing is part of ISIS. This project includes a description of all logical data controls at the microdata level performed during electronic data collection. The electronic questionnaire and information system ISIS itself provides many arithmetic and logical checks between variables, which we distinguish between serious and informative. Data collection is provided by the office of the SOSR in Nitra. After the deadline for submission of the statistical questionnaire, the reporting units that did not respond are contacted again to fulfil their legal obligation. In case of serious errors in the form, this form is not accepted and with the help of experts from the regional office its correctness is ensured so that it can enter into the data processing. Automatic validation checks during data collection and informative checks are incorporated with the aim to follow logical checks, reducing the rate of partial non-responses, anomalies and outliers. The purpose of this process is to minimize errors already in the data collection itself and subsequently during data processing. The basic step in the process of calculating unit non-response is the analysis of the population with regard to the state of activity of the reporting units. For this purpose, we use a specific classification of responses and non-responses codes. Individual codes describe active and inactive units and are assigned to each reporting unit. Subsequently, we determine the population of active units entering the data processing.
Weighted unit response rate is 0,895931. It was counted for reference month September 2024. Turnover was used as weighting variable.
Response rates for September 2024 is 82,46 %.
14.1. Timeliness
Data are released in line with the Release calendar. There are no differences in timeliness between the different aggregation levels or between the statistical variables presented .
Data dissemination in the public database Datacube is in accordance with the set up deadlines.
Data are disseminated on 42. day after the reference period.
Monthly T+42 days except for division 47 of NACE Rev.2 disseminated T+30 days.
14.2. Punctuality
Publication deadlines were met.
15.1. Comparability - geographical
The same statistical concepts are applied for the entire area of Slovak Republic.
15.2. Comparability - over time
Comparable time series are available since January 2000.
15.3. Coherence - cross domain
The following data comparison analysis is done:
- comparison of monthly survey results with quarterly data surveyed for the purposes of national accounts (for the calculation of quarterly GDP).
- comparison with structural business statistics data.
- a regular meeting of the STS experts with the national accounts experts is organised.
- the trends of the STS data are compared with the business tendency surveys.
The analysis shows very good compliance level in case of parts of population surveyed exhaustively. Some differences appear when comparing data from monthly, quarterly and yearly samples, which are the subject of further detailed data analysis.
15.4. Coherence - internal
There are no problems with internal consistency. At present chain-linking is not applied.
SOSR regularly monitors the cost and burden of reporting units. As part of the optimization of statistical surveys, it takes measures aimed at reducing their burden using administrative data resources if they are available in the required quality and at the specified time.
The cost and burden measurement at the level of European Statistical Products is in competence of the Resources Directors Group within Eurostat.
17.1. Data revision - policy
The Revision policy regulates the general rules and procedures applied in revisions at the SOSR. The same revision policy applies to national and international users. In accordance with the Revision policy, the reason of the revision is always indicated.
The Revisions policy as well as the Revisions calendar is available to users on the SOSR web portal.
SOSR distinguishes the following revisions:
From the content point of view:
- incorporation of better quality data based on a more complete source, including replacing imputations with collected data
- correction of data as a result of updating seasonal factors and changing the base period
- data modification based on more accurate methodology (in concepts, definitions and classifications) and changes in statistical methods
- performing corrections in source data and calculations.
In terms of time, SOSR divides the revisions into:
- ordinary revisions are revisions without significant modifications of the methodologies. These are usually more significant data corrections, including large values obtained from new sources. They are carried out periodically on precisely set up dates, to update monthly and quarterly data, until the next publication of the data
- annual revisions are revisions that are made when all monthly and quarterly data are available and more detailed results from annual surveys are already available
- extraordinary and major revisions are revisions of definitive data due to significant methodological changes resulting from revision of methodologies, changes in procedures and statistical-mathematical calculation methods or data corrections. An extraordinary revision may result (e.g. by changing the definition) in break in time series data comparability.
The policy on vintage database is laid down in the Revision Policy of SOSR.
Vintage database of raw data exists in source database and is not publicly accessible. Data and documents regarding the revision is kept. General information about revision and methodological explanation is published, if relevant.
Coherence of the revision policy is respected for the data released nationally and disseminated to Eurostat.
17.2. Data revision - practice
The main source of information for routine revisions are new or revised data from reporting units. The aggregates and components are then revised and disseminated at the same time. The publication of revised data is communicated in advance by a notice of revision indicating the date of publication of the revised data. The notice is published on the website of the SOSR at least 2 days before the publication of the revised data. Information on regular and annual revisions is also part of the methodological explanatory notes of the relevant monthly, quarterly and annual publications and relevant databases of the SOSR, as long as the revisions apply to the data in databases. Revised data are usually supplemented with information about the reason and revision evaluation, which are published on the portal at the time of publication revised data.
At present, numeric information on the size of revisions of data is not relevant due to the change of the observation unit to the Kind of Activity unit and the base year.
18.1. Source data
Reporting units with principal activity in Divisions 05 - 39, 41 - 43, 45, 46, 47, 55, 56, 49-53, 58-63, 68-71, 73, 74, 77-82, 90-93, 95, 96 and Groups 85.5-6 of SK NACE Rev. 2. with 20 and more employees registered in the Statistical business register and enterprises in the Statistical Business Register with less than 20 employees that have an annual turnover in excess of 5 Mill. EUR. Stratified random survey of small enterprises with less than 20 employees based on the activity (3-digit NACE), employment (0-9, 10-19, 20+ employees).
There are estimates on data for small enterprises from the monthly sample survey and on the self-employed persons based on data from the business register and from data obtained from the social insurance company.
Variable wages and salaries is reported in EUR.
18.2. Frequency of data collection
Monthly data collection.
18.3. Data collection
The regional office of the SOSR in Nitra is responsible for data collection. From January 1, 2016, reporting units (legal entities, natural persons - entrepreneurs) are required to electronically submit statistical reports in accordance with the amendment to Act No. 540/2001 Coll. on state statistics as amended by Act no. 326/2014 Coll. (hereinafter referred to as the law), which contains new rules for submitting statistical questionnaires.
The completed statistical questionnaire must be submitted electronically no later than the 16th day after the reference period on the website www.statistics.sk. In the event that the reporting unit has not submitted the electronic questionnaire, it is contacted by the relevant regional office of SOSR.
Response rates for September 2024 at the time data are provided to Eurostat and at first published nationally
Retail trade 79,28%.
Trade, Accommodation and food service activities 80,47%.
18.4. Data validation
The data entry, data completeness and statistical control are organised by specialised regional offices of the SOSR.
SOSR distinguishes between two levels of data checks:
1/ Formal checks, which are realised in the process of data entry automatically; (compatible with Validation level 0 and 1)
2/ Informal checks aim of which is to control the complexity and relations among the variables ((compatible with Validation level from 2 to 5).
According to the importance there are classified 2 basic types of checks:
I – Informative checks- this check gives the additional information, which is important for the following process of corrections. It informs also about some inconsistencies in the state of fulfilment of the questionnaire, about item non-response, exceeding stated limits etc.
Z – Check of great importance - it is mostly check indicating the exact error and it must be always corrected or explained.
Most of the errors are directly consulted with the reporting units by our regional offices.
18.5. Data compilation
Non-response for active reporting units is corrected by data imputation. The results for the population of active enterprises are grossed up using the Horwitz-Thomson estimator in accordance with survey stratification. Initial weights are modified due to non-response rates and unit inactivity. Administrative data and a model approach are used for estimates for self-employed persons.
18.6. Adjustment
SOSR uses JDemetra+, version 2.2, using TRAMO-SEATS method. As refresh from period to period we use partial concurrent adjustment + Last outliers. Concurrent adjustment is done once a year.
SOSR usually uses predefined models, but this can be changed if we can not find seasonality correctly. In this case we communicate with our colleague responsible for seasonal adjustment at our NSI.
For details on adjustments of the particular variables please see the annexes.
No further comment.
