Dublin South (Dáil constituency)

Dublin South was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas, from 1981 to 2016 representing an area in the south of County Dublin (later Dún Laoghaire–Rathdown and South Dublin). A previous constituency of the same name existed in Dublin City from 1921 to 1948. The method of election was proportional representation by means of the single transferable vote (PR-STV).

1921 to 1948
A Dublin South constituency existed in Dublin City from 1921 to 1948. The first constituency of this name was created by the Government of Ireland Act 1920 as a 4-seat constituency for the Southern Ireland House of Commons and a single-seat constituency for the United Kingdom House of Commons at Westminster, combining the former Westminster constituencies of St Patrick's and St Stephen's Green. At the 1921 election for the Southern Ireland House of Commons, the four seats were won uncontested by Sinn Féin, who treated it as part of the election to the Second Dáil. It was never used as a Westminster constituency; under s. 1(4) of the Irish Free State (Agreement) Act 1922, no writ was to be issued "for a constituency in Ireland other than a constituency in Northern Ireland". Therefore, no vote was held in Dublin South at the 1922 United Kingdom general election on 15 November 1922, shortly before the Irish Free State left the United Kingdom on 6 December 1922. It was restructured by the Electoral Act 1923, the first electoral act of the new state.

1981–2016
A new constituency was created by the Electoral (Amendment) Act 1980 and was first used at the 1981 general election. This Dublin South (1981–2016) was one of Ireland's most affluent constituencies. The 2006 census reported that residents tended to have higher-than-average levels of educational attainment, especially in terms of third-level qualifications, and were much more likely to work in professional and managerial positions. "Volatile, unpredictable and utterly ruthless, Dublin South voters have hired and fired TDs with abandon over the years" – The Irish Times description of the constituency in August 2012.
