An election to all 40 seats on South Dublin County Council was held on 24 May 2019 as part of the 2019 Irish local elections. South Dublin was divided into 7 local electoral areas (LEAs) to elect councillors for a five-year term of office on the electoral system of proportional representation by means of the single transferable vote (PR-STV).
Following the recommendations of the 2018 LEA boundary review committee, the boundaries in South Dublin were altered, as two of the LEAs at the 2014 South Dublin County Council election exceeded the upper limit of 7 councillors set by the 2018 Committee. Changes were also made to reflect population shifts revealed in the 2016 census.[1] [2]
