Scotland’s Census 2021 question testing conducted by ScotCen Social Research

NRS has committed to carrying out further testing around the sex question and guidance. We have asked ScotCen Social Research to conduct a survey to test questions that may be included in Scotland’s Census 2021. The aim of the survey is to see whether these questions are acceptable, easy to complete and produce reliable data.

Around 6,500 randomly selected addresses in Scotland will receive an invitation letter from ScotCen to take part in this study. Trans and non-binary people are also being recruited separately to take part in this testing. Taking part will involve completing a short online questionnaire.

All information provided will be treated in strict confidence under the Data Protection Act 2018.

If you have received an invitation letter, please follow the instructions and complete the questionnaire. This is your chance to tell us what you think.

If you have any questions about the questionnaire, you can contact the ScotCen office by email or by calling free on 0800 652 0501.

Any media enquiries should be sent to
