A central locus of electoral ergonomics is the polling station. What buildings do they use and how are they selected? Can this include private buildings or only public ones? Religious buildings or only state sector ones? Do they follow a standard layout? What are the rules about the average number of voters per polling station or the distance between citizens and where they vote? Does the country use mobile polling stations or any other non-standard polling station? Are there multiple booths in each station and are they curtained? This category dissects these aspects of how polling stations compare across the world.
