Dáil Constituencies 1918-2012

The table below shows the number of seats in each Dáil constituency at each boundary revision. Valid constituency names for the next election are shown in bold; names of constituencies which no longer exist are preceded by a bullet. Area summaries are shown in bold. The 1959 Revision was found to be unconstitutional by the High Court.

Please note that in this table constituencies are grouped according to name only, and there may be large geographical and electoral variations in similarly named constituencies. Each constituency appears only once in the list below, with cross references where appropriate. See the General Election Boundaries constituency details for smaller tables with no need for cross references (not yet updated with 2007 revision).

    *The 1959 revision - the Electoral (Amendment) Act, 1959 - was found to be unconstitutional.
    The original Bill had proposed 142 members, but this was increased to the maximum possible
    of 144 during the Committee Stage in the Dáil, the extra seats being allocated to Dublin South East
    and Wexford. For an outline of the constitutional position see the Dáil debate on the Final Reading
    (19 November 1959).
