80 million people globally claim Irish ancestry - why the release of 1926 Irish census records is so momentous

Key Points:

• The 1926 census of independent Ireland, containing nearly 3 million records, has been released online for free, offering valuable insights into Ireland’s population and its global diaspora of around 80 million people claiming Irish ancestry.
• This census is historically significant as it was the first full census after the establishment of the Irish Free State in 1922 and the first to allow completion in the Irish language (Gaeilge), focusing on family units rather than households.
• The data reveal socioeconomic conditions of the time, including employment patterns with over half engaged in agriculture nationally, regional disparities, and concerns about population decline, delayed marriage, and fertility rates post-World War I and the influenza pandemic.
• The release helps fill gaps left by the destruction of earlier Irish records during the civil war and offers opportunities to explore cultural, political, and social questions, such as attitudes toward the new police force and the status of marginalized communities like sex workers.
• Users are advised to be patient due to high demand and to use creative search strategies considering variations in names, place names, and the limited information available for institutionalized individuals, whose privacy was protected by recording only initials.
