The constituency elects four deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV).

The constituency comprises Ballyfermot, Bluebell, Chapelizod, Crumlin, Drimnagh, Dolphin's Barn, Inchicore, the Liberties, Kimmage and Walkinstown.

The Electoral (Amendment) Act 2023 defines the constituency as:[6][7] the Kimmage, Rathfarnham, Rathfarnham South, Rathmines West and Terenure wards; that part of Crumlin West ward which is not included in the constituency of Dublin South-West; Transfer of Mansion House, St. Kevin's, South Dock and part of Royal Exchange to Dublin South-East; Transfer of Kilmainham to Dublin South-West.

[49] The seat was won by the Labour Party candidate Mary Upton, sister of the deceased TD.

John O'Connell was Ceann Comhairle at the dissolution of the 23rd Dáil and therefore deemed to be returned automatically.
