Important information about your data
The 1926 Census will be published on the National Archives website on 18 April 2026.
This is required under the Statistics Act 1993, which states that individual census returns must be made public 100 years after the census was taken.
However, if your personal information appears in the 1926 Census, it is protected under General Data Protection Regulations (GDPR).
Your right to opt out
If you do not want your personal details to appear on your household’s 1926 census return, you have the right to opt out.
If you choose to do this, we will remove (redact) the lines that relate to you.
