Information about sexual orientation has not previously been collected in the census. Following feedback from the 2021 Census topic consultation, we committed to exploring whether to include a question on sexual orientation in the 2021 Census and published our outline Sexual identity research and testing plan.

We included a question on sexual orientation in the 2017 Test. You can see the findings of this in the 2017 Test report. Findings from our other research can be found in the 2021 Census topic research report.

Further question development work is being carried out before our recommendations inform a government White Paper in 2018.
