StatCentral.ie was set up by the Central Statistics Office (CSO) as the portal to Ireland's Official Statistics. The site was used to host official statistics and metadata from the CSO as well as government departments, agencies and other state bodies. Since then data.gov.ie launched as Ireland's open data portal to provide easy access to datasets held by public bodies. It is operated by the Department of Public Expenditure and Reform. The Central Statistics Office has now taken the decision to decommission StatCentral.ie.
