Census of Ireland

The Census of Ireland is typically held on a quinquennial basis by the Central Statistics Office to determine the population of the Republic of Ireland. The most recent census was held in 2022. As of November 2022, the next census is planned to occur in 2027. Prior to the establishment of the Irish Free State in 1922, censuses covered the entire island of Ireland as part of the United Kingdom. The last all-Ireland census was the 1911 census of Ireland, no census having taken place in 1921 due to the Irish War of Independence.
