The ensus is carried out based on the Act No 332/2020 Sb, on the 2021 Population and Housing ensus and on a change of the Act No 89/1995 Sb, on the State Statistical Service, as amended (hereinafter referred to only as „the 2021 ensus Act“). The ensus is carried out so that anonymised data on the entire population, its distribution, demographic, social, and economic characteristics, composition and way of dwelling of households are available, namely in mutual relationships from a nationwide perspective, even in the smallest territorial detail. These data cannot be found out in another way yet. The ensus is a worldwide event coordinated by the United Nations.

The Czech Statistical Office (hereinafter referred to also only as “the ZSO“) is the personal data controller (or “the ontroller“); it organizes, manages, coordinates, and provides for the preparation of the Population and Housing ensus (or “the ensus”).

For personal data processing, the CZSO uses in some cases services of processors. With the processors, the CZSO has concluded relevant contracts ensuring personal data protection; the processors process data solely based on instructions of the CZSO. Within horizontal cooperation on the Census, the following are the main processors for the CZSO: Česká pošta, s. p. (the Czech Post, state enterprise) and Státní pokladna Centrum sdílených služeb, s. p. (the State Treasury – Shared Services Centre, state enterprise).

The Census process can be broken down to phases as follows:

• Census preparation (including the pilot Census);
• carrying out of the Census, i.e. the data collection;
• processing of data from the Census.

Within the process of the Census preparation, during the pilot Census (that serves to check feasibility of the whole process of data collection and processing), both online census and additional field survey were tested on a small sample of the population.

The primary purpose of personal data processing within the Census project is, in accordance with the 2021 Census Act, to create and make available statistical information for the whole territory of the Czech Republic about natural persons, households, dwelling and housing stock as at the decisive moment of the Census.
During the first phase of the Census, i.e. during the Census preparation, and during the so-called pilot Census, the purpose of the processing of personal data is to check feasibility of the whole process of data collection and processing and to optimize setting of parameters for all processes and systems, including taking over of data from administrative sources. The Census is a “one-shot” process and as such it has to be set flawlessly. Without this phase, it would be impossible to duly fulfil the legal obligation of the Controller.

The CZSO applies all personal data protection principles related, first of all, to lawfulness, correctness and transparency, purpose limitation, data minimisation, accuracy, storage limitation, integrity and confidentiality, and, last but not least, responsibility.

For the aforementioned concrete purpose of carrying-out of the pilot Census, the CZSO processes personal data of natural persons subject to the Census or rather persons who participate on a voluntary basis in the Census preparation.

Administrative data are taken over from information systems of the public administration in order to reduce administrative burden of the population and to enable wider use of administrative data sources in statistics both in accordance with the provision of the Section 9(a) of the Act No 89/1995 Sb, on the State Statistical Service and pursuant to the Article 17(a) of the Regulation (EC) No 223/2009 of the European Parliament and of the Council of 11 March 2009 on European statistics.
Via census forms (questionnaires), mainly those data are surveyed that (for the purposes of the Census) cannot be taken over from administrative data sources. The scope of personal data surveyed via census forms is determined in the provision of the Section 8 of the 2021 Census Act.

Processing of personal data provided by you during the preparation of the Census is essential for the performance of a task carried out in the public interest or in the exercise of official authority vested in the Controller based on the 2021 Census Act. The legal basis for the processing is also laid down in the relevant provisions of the European Union, especially by the Regulation (EC) No 862/2007 of the European Parliament and of the Council of 11 July 2007 on Community statistics on migration and international protection and repealing Council Regulation (EEC) No 311/76 on the compilation of statistics on foreign workers, and Regulation (EC) No 763/2008 of the European Parliament and of the Council of 9 July 2008 on population and housing censuses.
The CZSO carries out the so-called pilot Census in order to fulfil lawful duties consisting in technical preparation for receiving of data and their processing in order to subsequently create and make available statistical information for the whole territory of the Czech Republic about natural persons, households, dwelling and housing stock and to fulfil the public interest in fulfilment of this task, inter alia, by realization of processing of personal data provided on a voluntary basis during the preparation of the Census, i.e. before the real Census in 2021.

The CZSO will erase and destroy personal data (you provided to it for the aforementioned purpose) on an ongoing basis, namely always right after they are no longer necessary for further processing. The latest date possible for the erasure or destruction of personal data is 26 March 2021; however, the expected period is much shorter (within several weeks).

Protection and security while processing personal data are guaranteed by a technical solution that keeps strict security standards and observes related legal norms. The CZSO uses maximally secured hardware and software solution and information systems located in the highly secured environment.
During the Census, data confidentiality protection and data security will be ensured throughout all phases of the Census – at the entry of the data into the system, during the processing, and, subsequently, also at the output while releasing the results.

Personal data obtained from the Census will not be provided to third parties.

  Within the pilot (trial) Census, when processing that is essential for the performance of a task carried out by the CZSO in the public interest and concurrently in the exercise of official authority is the legal grounds for the processing of personal data provided by you, you may due to reasons pertaining to your concrete situation lodge an objection to such processing.
