The Irish Social Science Data Archive (ISSDA) has been established under the auspices of ISSC. The ISSDA holds, processes and harmonises machine-readable data from surveys, census material, geographical data bases, election results and so on, and makes them readily available to users in the academic, public and commercial sectors. Managed jointly by UCD and the Economic and Social Research Institute (ESRI) - Ireland's largest and most experienced survey research agency - the ISSDA also has the collaboration and support of the Central Statistics Office (CSO).
