Your data and security : Overview
By filling in the census, you played your part in building a picture of us all. This helps decide how services are planned and funded in your local area.
Keeping your data safe
The safety of your information is our top priority. You cannot be identified in the statistics we publish. The personal information you give us is protected by law.
Personal information is any information that could allow you to be identified, for example your name, address or date of birth. We do not share this with anyone who makes decisions about you or any services that you get. This includes things like taxes, benefits, residency applications or immigration status.
All our systems, staff and suppliers must protect your confidentiality by law. Laws in place that cover protection of your data include the:
- Data Protection Act 2018
- UK General Data Protection Regulation (GDPR)
- Census Act 1920
- Statistics and Registration Service Act 2007
Your census record is kept secure for 100 years and only then can it be seen by future generations.
This video explains how we keep census data and personal information safe and secure.

Independent Security Review
At the ONS, we want you to be confident that all the information we collect during Census 2021 is safe and secure.
To support this, we, and the Northern Ireland Statistics and Research Agency (NISRA), commissioned an independent review of our security arrangements.
