1. 2021 Census Topic Consultation Statistics User Forum 17 June 2015 Ann Blake, ONS

2. Planning the next census – and more! The Census Transformation Programme (CTP) is the programme of work to deliver the online census in 2021 and also to make best use of admin data, as a springboard for the future. The topic consultation is our first step towards understanding what users need from the 2021 Census and the wider Census Transformation Programme.

3. What do our users want from the census? On 4 June, we launched our 2021 Census topic consultation for England and Wales. We are asking users for their requirements the 2021 Census questionnaire might cover. Anyone can take part in this consultation and it is open until 27 August.

4. About the census topic consultation The initial consultation is to gather requirements for the 2021 Census, which informs question development and testing informs any further topic specific consultation informs prioritisation of admin data work enables those activities to happen in advance of the Census Test planned for 2017

5. Our consultation approach is similar to 2011 A principle of minimal change but providing an initial view on what’s in/out/borderline Consulting about information requirements by main topics Making admin data intentions clear - Some requirements may be met through admin data, e.g. income We will aim to harmonise topics across the UK - But consultations will occur at different times. NRS, NISRA currently assessing own timings Use of appropriate digital tools - Citizen Space an online platform for consultation High-level approach

6. Citizen Space - Taking part is easy We use Citizen Space – an online consultation platform widely used by government – to host our 2021 Census topic consultation and collect responses People can access Citizen Space directly https://consultations.ons.gov.uk/census/2021-census- topics-consultation or the link is available from the ONS and Welsh Government websites, and from GOV.UK https://consultations.ons.gov.uk/census/2021-census- topics-consultation

7. What about admin data? Potential to use admin data to supplement or replace information collected by the census Some requirements may be met through admin data, e.g. income We will produce an assessment to evaluate our progress towards an admin approach Reaffirming our measures/commitment to continuing to protect the confidentiality of census and admin data All admin datasets with person identifiable information are held as anonymised datasets in a Statistical Research Environment (SRE) with strong security safeguards
