Figures as of 25 Sept 2026. Postal districts have no published boundary, so each site is placed from the Eircode or “Dublin 15” in its own address (32 here), or else from the Eircodes of the nearest addresses on the Valuation Office list, the Property Price Register and planning applications (1,393 here). Sites where they disagree are left out.
