Questions on sexual orientation and mental health in Census 2027

By Gráinne Ní Aodha, PA

Questions on gender, sexual orientation, and mental health will be included in the next census in 2027.

The next census will also be available to be filled in online for the first time and will again include a time capsule option.

The Government agreed this week with the next census date of May 9th, 2027.

The census, held every five years, asks Ireland’s population about their housing, education, health and employment situation with the aim of giving a snapshot of the country.

On housing, Census 2027 will ask people for their ‘usual residence’, counting people where they normally live, rather than where they are physically present on census night.

Following a public consultation, new questions will be included in Census 2027 covering gender and sexual orientation, mental health, qualification pathway (academic vs employment-based), and overnight parking.

Updates have also been made to existing questions on ethnicity, education, working from home and commuting patterns.

The time capsule, first introduced in Census 2022, will return, allowing people to leave a message for future generations.

More than 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.

Government Chief Whip and Minister of State with responsibility for the Central Statistics Office (CSO), Mary Butler confirmed the changes on Friday.

“The Census is an important data collection point every five years to assist Government in policy-making in a range of areas.

“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.”

Ms Butler added: “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 schools initiative for Census 2027 and will prepare resources for schools to use.”

“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.”
