CSO Electoral Divisions - National Statistical Boundaries - 2022 - Generalised 20m
CSO EDs are a statistical geography that aligns closely with the official ED boundary. EDs are comprised of whole Small Areas. In a small number of cases, CSO EDs do not align with the official boundary, where EDs are amalgamated to ensure statistical confidentiality or where a change was required to ensure better CSO ED/CSO alignment.
