The release and provision of statistical information is conducted in compliance with the Act (NC SR) No 540/2001 Coll. on state statistics, (pdf - 234 kB) as amended.

The release and provision of statistical information have to fulfil the criteria of the European Statistics Code of Practice, namely the timeliness, accuracy, reliability, relevance, clarity, impartiality, objectivity, professional independence, cost-effectiveness.

Units providing statistical information

The main actors in the system of information provision are the Information Service of the Central Office and the Regional Offices (further on "units providing statistical information") of the SO SR. These units receive all orders and requests for statistical information; provide information on publications, statistical data availability, possibilities and financial conditions of non-standard statistical processing. They provide consultancy on possible methodological issues, advice on utilisation of statistical information and ensure the satisfaction of the requests of the users. The main sources of information are outputs from statistical data processing from statistical surveys and administrative data sources. The Information Provision Units of the Central Office also provides help for those users searching data on European statistics at the website of Eurostat, the Statistical Office of the European Union.

In order to improve the cooperation of units providing statistical information with the users, the Office focuses mainly on the development of the following activities:

  • to ensure a rapid and comfortable access to statistical information for all user categories,
  • to maintain close contact with the users in order to more precisely define their needs,
  • to identify the user needs via satisfaction surveys,
  • to enhance and maintain contacts with the media,
  • to explain the valid methodology and to inform about the actual changes and data revisions,
  • to inform the statistical users on the Office´s activities, products and services, possibilities and restrictions to data access.

First Data Release

An important principle of the public information dissemination is the timely information on the place and time of availability of statistical information and other products, their scope and content. To ensure this principle, the Calendar of the First Data Release has regularly been issued and it is available at the Office´s website.

Principles of the First Release and the Calendar of First Data Release

Principles of first release shall apply to:

  • data categories resulting from the principles of the International Monetary Fund Special Standard (hereinafter the “IMF”) for data dissemination, included in the Calendar of First Data Release (hereinafter the “Calendar”),
  • data categories with increased public interest and included in the Calendar,
  • basic results from special surveys and censuses (for example from the Population and Housing Census, Farm Structure Census),
  • data surveyed and processed according to special contracts with Eurostat,
  • publication outputs containing statistical information on the economic, social and demographic development for key indicators,
  • further information, data or outputs based on decision of the President of the Office.

The first release is performed in the form of an information report or a press conference. There is a standing rule, that all users have the right to be provided with information at the same time. For the first publication through a press conference, the printed materials are given to the participants prior to its commencement (not earlier than 9.00 am). At the same time they are available at the Office´s website.

Until the moment of the first release, the results of statistical surveys are under embargo. In exceptional cases it is possible to provide this data before their first release for working purposes to a government institution, under contractually specified conditions in accordance with the Regulation (EC) No 223/2009 of the European Parliament and of the Council Article 9 and Article 11, as amended and with the Code of Practice for European statistics (Principle No.6). The contract shall include a customer´s commitment not to provide the data concerned to any third party until the moment of publishing by the Office. The priority access to the statistics from any external user to the statistics before their release is limited, controlled and published at the Office´s website.

The publications containing information covered by the principles of first release and that have not yet been released via information reports, press conference or Office´s website, can be provided to the interested persons only on a day of the first release of data.

The Calendar contains the release dates of selected data categories resulting from the principles of the International Monetary Fund´s Special Data Dissemination Standard. These categories include- gross domestic product (GDP), consumer price indices, industrial product price indices, industrial production, foreign trade, employment and unemployment according to the Labour Force Sample Survey, average monthly wage from quarterly reporting. Data categories are extended by indicators with increased user interest (e.g. development of core and net inflation, development of harmonized indices of consumer prices, average prices of driving fuels in the SR, construction production, indices of other producer prices, monthly data on employment and wages in selected branches by statistical reporting, turnover in selected sectors, results of business tendency survey and the economic sentiment indicator, turnover in internal trade). The range of data categories within the scheme of first release could be extended on an ongoing basis.

The Calendar is available on the Office´s website, in the sector "Products", containing release dates for the upcoming four months. Dates are included as the right release dates, always at 9.00 a. m.

It is possible to change the stated release date only exceptionally, for particularly serious reasons. The public will be informed about the change of date through the website by the end of the working week, prevenient to the release week, in accordance with the Calendar.

The deadlines for data provision which are not guided by the principles of the first data release and by the Calendar, are set by the Office´s publication deadlines, data update in the public database and the timetables for automated processings of statistical surveys.

Catalogue of Publications and first release

To ensure the information of the public on the portfolio of publications, the Catalogue of Publications is compiled by the Office for the relevant year. Where appropriate, the Office issues publications also beyond the Catalogue of Publications.

The introduced titles present the results of statistical surveys and censuses, while taking into account the current needs of statistical users. The Catalogue of Publications contains brief annotations to all publications, the procedure for publication and ordering, periodicity of issue as well as information on the Office´s databases. The new value-added titles (containing analytical texts, data visualizations, data comparisons) have also been included when compiling the Catalogue of Publications.
