The municipality covered an area of 84 km², and had a total population of 10,337 (2005). Its last mayor was Poul Arne Nielsen, a member of the Venstre (Liberal Party) political party. The main town and the site of its municipal council was the town of Hårlev. Neighboring municipalities were Køge to the northwest, Rønnede and Fakse to the southwest, and Stevns to the southeast. Because the municipality formed a headland between two large bays, it is surrounded by water on three sides. To the northeast was Køge Bay (Køge Bugt).
