Ireland Census 1926

The 1926 Census of Ireland offers a deeply meaningful opportunity to delve into your Irish ancestry at a pivotal moment in the nation’s story. The census was taken on 18 April 1926.  It was the first census after the establishment of the Irish Free State or Saorstát Éireann, bringing you face to face with a generation reshaping their future.  

Census records are invaluable not only for family history research but also for understanding the fabric of local communities, neighbourhoods, and even the story of your own home. Through these records, you can discover where your ancestors lived, who shared their household or lived nearby, and the work that shaped their daily lives.  You may uncover whether your ancestors were Irish speakers, offering a personal connection to language and culture, or whether they lived in a bustling urban setting or a quieter rural landscape. Each detail brings you closer to their lived experience. 

This incredible collection was digitised and transcribed by the National Archives of Ireland.  Their teams worked through 1,266 boxes with over 700,000 household returns held in 2,494 canvas volumes. It was one of the largest archival projects the archive has ever undertaken. It is a comprehensive account of a population of 2.9 million people and over 630,000 households. 

The 1926 Census does not include the 6 counties of Northern Ireland (Antrim, Armagh, Down, Fermanagh, Londonderry/Derry, and Tyrone).  A separate census was taken for Northern Ireland, but unfortunately, those returns have been lost.  

After the census was taken, the original forms were transcribed by 21 young girls onto punch cards, which were then fed into tabulation machines.  The same method was used for the 1921 Census of England and Wales.  The tabulations were used to generate census statistics for the nation as a whole and for each individual county.  You can continue your census research by reviewing these volumes on Findmypast.  

Modifications

Findmypast has standardised several fields in the transcription data supplied by the National Archives of Ireland, including county, birth county, children born, years married, marital status, language, and relationship. Standardisation helps make records easier to search by cleaning and aligning the transcription data into a consistent format. When millions of records are digitised, original clerical errors from the census and small transcription mistakes can become more noticeable. Standardisation is used to correct these where possible. 

For example, our team removed entries where “years married” was recorded as more than 100, and corrected cases where “language” was transcribed as “England” to “English.” 

You can always check the original information by viewing the source images linked to each record.
