For any query in the FTB, where an area fails the rules, the data will be kept safe and not published. However, the same query for another area where sufficient protection has been applied by the other methods and the rules are met, the data will be released. This will allow more data to be published where it is safe to do so.
A phrase we do hear a lot in SDC is that ‘you can’t have it because of SDC’.
Without the SDC shield of protection, there greece rcs data wouldn’t be detailed published outputs or data accessible to all. Without the innovations in SDC methodologies behind the ONS dissemination systems, there wouldn’t be flexible, timely outputs that better meet user needs. Because of SDC and the hard work of many other teams within ONS, the Census 2021 outputs will be some of the most exciting yet!
More information on the SDC methods that will be used for the dissemination of the Census 2021 can be found in the Methodology Assurance Research Panel paper EAP125 – Statistical Disclosure Control (SDC) for 2021 UK Census (direct download link for the Microsoft Word document).
