Since the 1970s, Ireland has seen a rich tradition of national election studies, referendum research, and opinion polling around elections. The Irish Election Studies Archive (IESA), created by the Voters, Parties and Elections Specialist Group of the Political Studies Association of Ireland, brings together the data from these studies in one accessible place. Designed as a resource for researchers, students, and anyone interested in Irish politics, the IESA helps shed light on voting behaviour and the history of elections in Ireland.
