The municipality has no districts. But has 3 village centers or major neighborhoods. AlkenCentre, SintJoris (St. George) and Terkoest. AlkenCentre is located in the east of the municipality, neighboring Hasselt and Wellen. The parish is dedicated to St. Aldegondis and it is the oldest parish in Alken. The city hall, the CPAS, most shops and institutions are located here. SintJoris (St. George) is located south of Alken, neighboring SintTruiden and Nieuwerkerken. The parish is dedicated to St. George Patron Saint, known from the story of Saint George and the dragon. Terkoest located in the northwest of the town, neighboring Hasselt and Nieuwerkerken. The name Terkoest comes from an old Dutch word for marshy areas. A fourth neighborhood in Alken grew around the station, though this station area is not developed into a real village. The station was closed for a while and the local school closed.
