> Candidate votes for the gmina as the Krajowe Biuro Wyborcze's candidate file prints them, with valid votes as the file prints them for the gmina. Polling-district (obwód głosowania) figures are as the Krajowe Biuro Wyborcze's polling-district file prints them, and the gmina's electors and ballots are their sums; ballots are those taken from the ballot box, and invalid is the ballots less the valid votes. Polling districts are described by addresses, not mapped, so they have no area.
