Introduction to the Census 2021 outputs consultation webinar – 15, 16 July 2021 and 3 August 2021

On 13 July 2021, we launched a public, 12-week Census 2021 outputs: content design and release phase proposals consultation.

In the consultation, we share our plans for the content design and release of Census 2021 outputs. You have the opportunity to tell us if our plans meet your needs. You are also able to share any priorities or changing needs you have for Census 2021 data and analysis. Your feedback is helping us to make decisions on the final design of the Census 2021 outputs for England and Wales.

To introduce the consultation, we held consultation launch webinars on 15 July, 16 July and 3 August 2021. In each webinar, we shared:

  • the importance of consulting with you now

  • the shape of the Census 2021 data and analysis release plans

  • the types of questions we want your feedback on

  • how you can respond to the consultation

The slides from the webinar are available to view or download: Introduction to the Census 2021 outputs consultation.

We have provided a video recording from our consultation launch webinar in July. In this recording we discuss each section in more detail: Scope of the consultation.

Designing for quality in Census 2021 – webinar series

With the Census in England and Wales taking place on 21 March 2021, we created a programme of webinars to showcase our plans for design and quality assurance. The series, which was carried out through November and December 2020, included a high-level introductory overview as well as "In Focus" sessions that outlined specific aspects in more detail. These webinars gave attendees the opportunity to ask questions and provide feedback.

2021 Census and statistics about the Sikh community – 23 October 2017

The ONS invited organisations and individual experts who may have an interest in statistics about the Sikh community to an open meeting on 23 October 2017 in London. We shared progress in developing the questions for the 2021 Census and discussed how the need for statistics about the Sikh community can be met by the ONS.

The ONS had conducted an online survey with households in Wolverhampton and Hounslow, and interviews with members of the Sikh community. Results from the research and our current assessment of questions were presented. There was an opportunity for feedback and discussion.

2021 Census roadshows – July 2017

The ONS ran an extensive consultation on the content of the 2021 Census in England and Wales. Following this, we held four regional roadshows to share the latest news on the proposed content for the 2021 Census questionnaire.

This was an opportunity to ask experienced ONS staff questions and to find out about progress towards an Administrative Data Census beyond 2021. The roadshows covered:

  • a summary of question development and testing since publication of topic consultation outcomes and progress towards 2021 Census questionnaire design

  • developments towards meeting user requirements for data on sexual identity, gender identity and veterans

  • research and question development for ethnic group questions, including consideration of additional response options and online question design

  • the ONS's assessment of using Valuation Office Agency data to produce estimates of numbers of rooms

  • updates on other census topics including education, volunteering and central heating

  • latest news from the Administrative Data Census Project on progress towards an Administrative Data Census beyond 2021

The roadshows took place in:

  • Newcastle upon Tyne

  • Birmingham

  • Cardiff

Outputs reference group formed – April 2016

Ahead of the 2011 Census, the ONS established an "outputs working group" where a small group of users helped to develop Census outputs. This group was superseded by an "outputs reference group" for 2021 to provide a more reactive means of sharing plans. Rather than holding formal meetings involving travel from across the country, the new group largely holds meetings online. This is to reduce the burden on users and to be more reactive to what develops. An initial meeting of the group was held in April 2016 to test the technology that will be used in the 2021 Census.

Annual Research Conference: "Transforming the Census – to 2021 and beyond" – 28 to 29 June 2016

The aim of the conference was to inform stakeholders about the latest research, get feedback on the statistical design of the 2021 Census and Admin Data Census and reinforce confidence in the delivery of a successful programme.

The ONS presented research and plans around the move to a predominantly online Census in 2021 and the potential move to an administrative data-based Census after 2021. This included making the best use of all available data sources that are needed to produce better statistics for making better decisions. The agenda for the event can be found on Eventbrite. A list of the organisations represented at the conference can also be downloaded and you can see the session summaries. You can also read the full QA Panel Session responses, including answers to the whiteboard questions not covered on the day.

Valuable feedback and contributions from the many stakeholders who attended helps us to plan the 2021 Census and beyond.

The main themes discussed

The main themes to emerge from the thoughts and questions voiced at the conference are listed and remain the topics for discussion and research. The ONS welcomes an open dialogue with our stakeholders, so if you would like to contribute to these topics, please email us.

Census content and outputs

  • Considering what potential changes in the questionnaire design might deliver for users – focus group discussions on user requirements for new topics such as volunteering and gender identity.

  • The differences between Census and administrative data definitions of households in the context of an address frame for the 2021 Census and for producing household estimates in an administrative data-based Census.

Census and wider ONS transformation data collection

  • Understanding and dealing with non-response to online data collection methods – who are most likely to not respond?

  • Issues around understanding and measuring over coverage for the 2021 Census.

  • Wider digital transformation in the ONS and throughout government and how other National Statistics Institutes are digitally developing their Census.

Administrative data research

  • How other data (such as utility data, business registers and local authority information) may be used to help understand activity and address types, to build an enhanced address register for the benefit of both the 2021 Census and an administrative data-based Census.

  • How the quality of administrative data-based estimates can be measured and assessed against user requirements.

  • Gauging confidence (based on our latest assessment) in our progress towards an Administrative Data Census.

Market engagement supplier briefing events – February 2016

In May 2015, the ONS hosted the initial supplier briefing event for the Census Transformation Programme.
