Claim game

The group sits in a ring or around a table and is divided into the desired size of each team. The more people on each team, the more often you get to guess. The host of the game has a list of claims. Each team "has it" on its turn. Each round, one claim is shown to the group, except for the team that "has it". The guests the claim applies to stand up, while the rest remain seated. The team that "has it" must guess what the claim is based on which guests it applies to. Based on how difficult the claim is, 1-2 hints can be given to the team that "has it". Example: Claim: "I'm from {city, area, place}" and everyone who is from the given area stands up. Those who "have it" do not know what the claim is about, only who is standing up. What do those who stand upright have in common?
