RTÉ Documentary to Explore 1926 Irish Census with Dermot Bannon, Eileen Walsh and Mick Lynch
RTÉ has commissioned a landmark documentary series that will use the recently published 1926 Irish census — the first full census of the Irish Free State — to explore life on the island of Ireland a century ago, with architect Dermot Bannon, actress Eileen Walsh, and retired trade unionist Mick Lynch among the well-known personalities who will trace their family histories through the historic records in what promises to be one of the most compelling pieces of Irish public history television in years.Background
The 1926 census of the Irish Free State was the first comprehensive population survey conducted after the establishment of the new state following the War of Independence and the Civil War. It captured a society in profound transition: a country that had just emerged from years of conflict, was grappling with partition, and was beginning to define what it meant to be Irish in the modern era. The census recorded the names, ages, occupations, religions, and addresses of every person in the Free State — a snapshot of a nation at a pivotal moment in its history.
The records were sealed for 100 years, as is standard practice for census data, to protect the privacy of individuals and their families. Their release in 2026 has been one of the most anticipated events in Irish genealogical and historical research, comparable to the release of the 1921 census in England and Wales in 2022, which generated enormous public interest and drove a surge in family history research. The Irish census records are particularly significant because so many earlier Irish records were destroyed in the Four Courts fire of 1922, making the 1926 census an invaluable resource for anyone tracing Irish ancestry.
RTÉ has a strong track record in documentary programming that uses historical records to illuminate personal and national stories. The broadcaster's Who Do You Think You Are? format, which traces the family histories of well-known Irish personalities, has been consistently popular, and the 1926 census provides an extraordinary new resource for exactly this kind of storytelling.
Key Developments
The new documentary series, announced on 7 May 2026, will feature several well-known personalities using the 1926 census data to uncover stories about their own families or communities. Dermot Bannon, the architect and television presenter best known for Room to Improve, will explore his family's history in the context of the housing and construction landscape of 1920s Ireland. Actress Eileen Walsh, known for her roles in Normal People and Skins, will trace her family's story through the records. Retired trade unionist Mick Lynch, who became a prominent public figure during the RMT strikes in Britain, will use the census to explore his Irish roots and the labour history of the period.
The series will be produced in partnership with the National Archives of Ireland, which holds the census records, and will include contributions from historians and genealogists who will provide context for the personal stories uncovered. The 1926 census is available to search online through the National Archives website, and the documentary is expected to drive a significant surge in public engagement with the records.
Why It Matters
The 1926 census documentary matters because it arrives at a moment when questions of Irish identity, history, and memory are particularly live. The centenary of the Irish Free State has prompted extensive reflection on what the state has achieved and what it has failed to deliver — on housing, healthcare, emigration, and the treatment of women and children. The census records provide a granular, human-scale counterpoint to the grand narratives of national history: they show not the politicians and generals, but the farmers, teachers, domestic servants, and factory workers who made up the fabric of Irish society in 1926.
The inclusion of Mick Lynch is particularly interesting. Lynch, who is of Irish descent, became one of the most recognisable trade union voices in Britain during the 2022-23 rail strikes, and his engagement with Irish history through the census will resonate with the large Irish diaspora community in Britain. For viewers in Northern Ireland, the 1926 census is also a reminder of partition's immediate human consequences — the records capture a society that had just been divided, with families and communities split across a new border.
Local Impact
For viewers across Ireland and the Irish diaspora in Britain, the documentary offers a rare opportunity to connect with family history through a major public platform. The National Archives has reported a significant increase in online searches of the 1926 census since its release, and the RTÉ series is expected to drive further engagement. For genealogists and local historians in Northern Ireland, the 1926 census is a particularly valuable resource, given the destruction of earlier records — and the documentary may prompt Stormont to consider how it can better support access to historical records for people tracing Northern Irish ancestry.
What's Next
A broadcast date for the documentary series has not yet been confirmed, but it is expected to air on RTÉ One in the autumn of 2026. The National Archives of Ireland has indicated that it will publish additional educational resources alongside the broadcast to help viewers engage with the census records themselves. Readers should watch for: the announcement of additional participants in the series; any partnership with BBC Northern Ireland to broadcast the documentary to Northern Irish audiences; and whether the series prompts a broader conversation about the digitisation and public accessibility of Irish historical records.
