SDC Handbook

There are now many Safe Settings around.  A key component of how they work is about ensuring that statistical results created within them do not enable people or organisations that the data are about from being identified.  It’s also about ensuring that no confidential about the people or organisations in the data are released.  This is known as ‘statistical disclosure control’ (SDC).

Members of the SDAP group have produced an SDC Handbook to enable output checkers who work in Safe Settings, to learn and assess statistical results before releasing them into the world.

The Handbook can also be used by Safe Setting users (i.e.  analysts, researchers).

We began this project in April 2018.

Now we’re happy to release our BETA version 1.0!

There are two parts to the Handbook.

SECTION A describes what SDC is all about, and how to undertake SDC assessments on a variety of statistical results commonly produced in Safe Settings.

SDC Handbook BETA

SECTION B is about how to implement SDC systems in an organisation, and how to manage requests for outputs.

SDC Handbook Part 2


To bring this Beta version about, the authors have pooled their collective knowledge of SDC and explained how they undertake SDC assessments. 

However, we acknowledge that there is more work to be done, and that subsequent versions should be updated.  There are others who undertake these roles who we haven’t spoken to and who could contribute their own examples.  There are researchers in statistical confidentiality and privacy who we would be grateful to hear from, particularly to ensure the technical accuracy of the contents.

We’d like to hear from anybody who has ideas about how this Handbook could be improved.

In the coming months, we will produce a professionally designed version and hard copy of this Handbook, and we intend to launch the Handbook at a workshop (t.b.c.).

Future work will also include developing this web page into an online resource, using examples and material from the Handbook.
