The information system of the Central Electoral Commission accumulates notations about the voter's vote. The dataset consists of four tables: "Election Rounds", "Electoral Districts", "Voters", "Voter Markings". The table "Election rounds" contains the election identification number, election name, election round identification number, election round number, information about the current election and the date of the election round. In the table "Electoral districts" you can find information about the district identification number and the name of the district during certain elections. The "Voters" table publishes the pseudonymized personal codes, gender and year of birth of individual voters (year of birth records are modified by adding random values ​​to ensure confidentiality). The "Voter markings" table shows the marking of a certain voter's vote in specific elections. In the table you can find information about pseudonymized personal codes, the election round and the district where the vote was taken.
