The fancy name of the place where a voter is assigned to go to cast their ballot. A voter's polling station is often listed on their voter registration card and usually has a one-to-one correspondence with a particular voting precinct. Public buildings like schools and libraries and not-for-profit buildings like churches are the most common polling station locations. Polling stations are also known by the equally vague polling place.
Usually there are reasonable rules about campaigning within a certain area of a polling station and about the sorts of people allowed to work at a station. In some areas of the world, international observers are required to ensure that the staff of a polling station is fair and accurate in their count. Regional Elections Boards generally receive the responsibility of running a fair election when elections are being held in a stable democracy.
