As another minder of the Greystones article I might add that you have a point, This very debate was is replicated somewhere (can't remember where) where one editor insisted in reducing  "grossly inflated population figures" for Dublin, Cork, etcetera by reverting to the population of the core City Council only; thus Dublin ended up with a population of 500,000 or so. From memory, the debate ended with Dublin getting it's 1.2 million restored on the basis that a local authority administrative area doesn't necessarily define the population of a town/city when the commonly accepted boundaries are very different. Charlesland is certainly in Greystones in my view; indeed a case could be made that Delgany  and Kilcoole are now merely parts of Greystones - but of course by the same reasoning Bray is part of Dublin's population. Thank God for Bray head and the Little Sugar Loaf!  ( )
