  • from and on entities of the national economy and their activities and
  • from and on natural person on their physical life and situation

    • from full research, general censuses,
    • from the research conducted with methods of representation,
    • from administrative sources.

The programme of statistical surveys of public statistics is a list setting out the thematic , subject and subjective scope and related duties.

Techniques used for transfering statistical data:

  • Internet (Reporting Portal, email)
  • face-to-face interview (using paper form or CAPI - interview recorded on a portable electronic device),
  • telephone interview (traditional or CATI - telephone interview assisted by computer program).


Since 2000 in all Statistical Offices, there have been Departments of Surveys dealing with the implementation of social and agricultural statistical research through a network of pollsters.

They carry out the research:

  • continuous,
  • cyclic,
  • one-time
  • and research commissioned and on individual order, not covered by the program of statistical research of public statistics.

Social surveys are voluntary, conducted with representative method.

Quotations and agricultural surveys are obligatory, and in the case of this research sampling is purposeful.

In the case of a large load of research there is the possibility of the involvement of employees performing their work on a daily basis in the Office (the so-called changing pollsters).

Reporting Portal

On 1 January 2009, the Central Statistical Office introduced as valid a safe form of electronic transmission of statistical data. In accordance with the program of statistical surveys of public statistics the entities of the national economy, for which the reporting obligation was established, shall transmit the data in electronic form to the REPORTING PORTAL of CSO. The portal made available applications that allow you to fill in the on-line application form. Signing in to the reporting portal of CSO is possible through previously activated account. For selected reports at applications off-line will also be made available that give you the opportunity to fill out reports on your computer, without the need for a direct connection to the Internet, and then send them electronically to public statistics.
