Census 2027 Date Confirmed with Major Changes to Survey Format

Ireland's next national census will take place on Sunday, 9th May 2027, with households able to complete the survey online for the first time. Minister Mary Butler confirmed the date following Government approval this week, alongside significant changes to how the census will be conducted.

The census, held every five years, provides vital data on Ireland's population, housing, education, health and employment to assist Government policy-making.

Mary Butler, Government Chief Whip and Minister of State with responsibility for the Central Statistics Office:

"I'm pleased to confirm that Census Night 2027 will be held on Sunday, 9th May 2027, and preparations are well underway to ensure its success. The Census is an important data collection point every five years to assist Government in policy-making in a range of areas."

The 2027 Census introduces a major shift in methodology. For the first time, households can complete the census online, though paper forms remain available for those who prefer them or require support.

Another significant change sees Census 2027 move to a 'usual residence model', counting people where they normally live rather than where they are physically present on census night.

Minister Butler:

"The introduction of an online response option for the first time will make it easier and more convenient for many households to participate. At the same time, we are fully committed to ensuring that everyone who wishes to complete the census on paper, or who needs support to do so, will be assisted. The census must remain accessible to all, and every effort will be made to support participation across every community."

Following public consultation and a national pilot survey, several new questions will appear in Census 2027. These cover gender and sexual orientation, mental health, overnight parking and qualification pathway (academic versus employment-based).

Minister Butler:

"Important questions on gender and sexual orientation in Census 2027 are positive in ensuring we collect accurate and inclusive data. In respect of the new question on mental health, the CSO has agreed to engage with stakeholders on the guidance around this question, particularly for younger respondents. The CSO intends to have a school's initiative for Census 2027 and will prepare resources for schools to use."

Updates have also been made to existing questions on ethnicity, education, working from home and commuting patterns. The popular Time Capsule, first introduced in Census 2022, will return, allowing people to leave messages for future generations.

Over 400 submissions were received during the public consultation process, with input from government departments, agencies, researchers and members of the public. A pilot survey in September 2024 tested the new format and questions, with feedback used to refine the final questionnaire.

Recruitment for field staff will begin in 2026, with approximately 3,800 support officers and 500 supervisors expected to be hired nationwide. The CSO will publish further updates and guidance in advance of Census Night.

Minister Butler:

"Census 2027 should provide a clear picture of Ireland's population and how we live. The changes being introduced reflect the feedback received and the need for data that supports inclusive, evidence-based policymaking. I want to thank all who contributed to the consultation and pilot process. Your input has shaped a census that is inclusive, relevant and future-focused."
