 In March 2005, Minister for Community, Rural and Gaeltacht Affairs Éamon Ó Cuív announced that the government of Ireland would begin listing only the Irish language versions of place names in the Gaeltachtaí as the official names, stripping the official Ordnance Survey of their English equivalents, to bring them up to date with road signs in the Gaeltacht, which have been in Irish only since 1970.This was done under a Placenames Order made under the Official Languages Act.At the time of the 2006 census of the Republic of Ireland, the population of the Gaeltacht was 91,862, approximately 2.1% of the state's 4,239,848 people, with major concentrations of Irish speakers located in the western counties of Donegal, Mayo, Galway, and Kerry.
