Copenhageners, e.g.

DANES

Think of the people from the Scandinavian country known for its pastries, fairy tales by Hans Christian Andersen, and a flag with a white cross.

This clue is a straightforward example of a crossword hint that points to a group of people from a specific place. "Copenhageners" refers to residents of Copenhagen, the capital of Denmark, so the answer is the demonym for people from Denmark—"DANES." There’s no wordplay here; it’s a direct reference to nationality based on the city given. Think of it like calling someone from Paris a "Frenchman" or someone from Tokyo "Japanese."
