Be careful! A unit may cover just the town or village, but it may include a big surrounding area. For example, in England and Wales rural districts — units with RD or RSD suffixes — may even exclude the places they are named after. The "Units covering this place" tab lists units whose boundaries contained Mountain Ash.
