User feedback
In our series of short videos, Census Office has endeavoured to cover the basics of the Flexible Table Builder. However, we are always looking to improve users’ experience and we recognise there may be other topics that would benefit from tutorial-style videos.
Please email census@nisra.gov.uk with topic suggestions for additional videos.
Statistical disclosure control approach
Statistical disclosure rules for the Flexible Table Builder are designed to return as much data as possible. We use three methods to ensure we protect confidentiality:
- Record swapping: to protect persons and household with unique or unusual characteristics.
- Cell key perturbation: to protect against disclosure by differencing.
- Disclosure checks: to protect against sparse tables that allow identification.
Read our paper on statistical disclosure control methodology for 2021 Census (PDF, 206 KB) for more information.
When creating a custom table, in some instances to prevent individuals being identified, limited or no results will be returned. Reducing the number or granularity of the variables you've chosen can help improve coverage. Watch our short video on improving your results to get more advice.
