Suppose you want to take a scientific poll about people’s opinion on a new boating law for Lake Blue. Who should make up your universe—all the people in the United States, only townspeople, only boat owners, only people who live on the lake, anyone who uses Lake Blue, or some other group?

Would it be a combination of towns people and people who use Lake Blue (this would include boat owners).

It would depend on what the law regulates, but in general, I would add to your group folks who live there, and property owners.
