Welcome
• We’re excited to launch our consultation:
‘Census 2021 outputs: content design
and release phase proposals’
• In this webinar we will share:
• Why we are consulting
• Release schedule and outputs prospectus
• The scope of the consultation
• How we will use your feedback
• How to respond to the consultation
www.sli.do 820387

Why are we consulting?
www.sli.do 820387

5. 5
The census counts everyone in England and
Wales
The cost and effort of taking a census is only worthwhile when
the results are provided to users in ways that allow them to
use the information to improve the decisions they make.
www.sli.do 820387

6. 6
Purpose of the census
All kinds of organisations, from local authorities to charities, use census information.
There are two main types of use:
1. Describing the population on Census day
2. Informing the decisions of the future
We want our outputs to help answer the most important questions facing society
today
Better
information
Better
understanding
Better
decisions
Better
outcomes

Aims of this consultation
• The consultation document and supplementary materials
act as a draft release schedule and prospectus
• The consultation is about what data we plan to produce
• How we produce the data is only discussed where it is
relevant to decisions on what we plan to produce
• Results will help us:
• identify any new or changed data needs
• prioritise the development of proposed outputs products
• finalise our release schedule and prospectus
• develop plans to supplement Census 2021 data
www.sli.do 820387

9. 9
Maximising the value of census
data in times of change
• We want to maximise the use and utility of Census 2021 data
• Census has always been a snapshot, but also used as the
best estimate for informing decisions many years later,
particularly where less alternative information available from
other sources
• The current period of societal change will likely mean that
some characteristics are subject to more rapid change
• We always planned to combine and supplement census data
with other sources, the focus of that work is now slightly
different

Summary of proposed release schedule
Standard outputs
Bespoke, restricted, or
commissioned outputs
Phase 2 – Release of multivariate data and more complex
analysis based on usual resident population
March 2022 to March 2023
Beyond March 2023
Phase 1 – Release of population and household estimates,
univariate data and analysis by topic, and area profiles
Phase 3 – Release of alternative population bases, small
population data, origin-destination data and microdata
Release of UK data and longitudinal or linked data analysis
www.sli.do 820387

12. 12
Phase 1 overview
• In Phase 1, we plan to release:
• Largely ready-made univariate data
tables
• Topic summaries equivalent to the 2011
Census ‘Quick statistics’
• Area profiles similar to the 2011 Census
‘Key statistics’
• We’re aiming for Output Areas to be the
main geographical base
www.sli.do 820387

13. 13
Phase 2 to 3 overview
• Across phases 2 and 3, we plan to release:
• Largely multivariate data
• Data tables equivalent to the 2011 Census
‘Local Characteristics’ and
‘Detailed Characteristics’
in phase 2
• Analytical insights work,
including data visualisation tools
• Commissioned table service
in phase 3

14. 14
2011 Census data dissemination model
The design of data outputs that cross-tabulate
variables is a balance of topic detail and
geographical detail
For 2011 Census outputs:
• Local Characteristics had less topic detail and more
geographical detail
• Detailed Characteristics had more topic detail and
less geographical detail
• Some commissioned outputs were possible that
were effectively Detailed Characteristics for smaller
geographies

15. 15
Census 2021 data dissemination ‘hybrid’ model
The 2021 dissemination model combines:
• Ready-made tables*, providing data tables for all areas
• They are similar in concept to the Local Characteristics
• They will give users data that is comparable over space and time
*Also the case for Topic Summaries (similar to 2011 Quick Statistics) and Area Profiles (similar to 2011 Key Statistics)
• Build-your-own table functionality, letting users choose their own combinations
of variables and detail
• What is made available will be dependent on the characteristics of the areas
being requested
• Provides users with flexibility to get more data that is specific to their needs
The specifications for these different products are detailed in the ‘Draft proposals for outputs data content’
spreadsheet, available from the “related links” section of Census 2021 outputs consultation.

16. 16
Beyond March 2023 product overview
• Beyond March 2023, we plan to release:
• UK outputs where data can be compared from
Census 2021 in England and Wales, Census
2021 in Northern Ireland and Census 2022 in
Scotland.
• More complex analysis of Census 2021 data
using other data sources

• Route to highest level of
education
• Students
• Not in employment, education
or training, (NEETS)
• Temporarily away from work
• Key or critical worker
• Skills mismatch

25. 25
Population-base specifications
We’re asking what data tables and analysis you need for alternative population bases.
The main population bases for
Census 2021 are:
• Usual residents
• Households
• Usual residents in households
• Communal establishments
• Usual residents in communal
establishments
• Household reference persons (HRP)
Alternative population bases are those that either:
• move usual residents to different locations
• report on a population that is not usually resident
The alternative population bases for Census 2021 are:
• Workplace
• Workday
• Out-of-term population
• Short-term resident
• Second address
www.sli.do 820387

26. 26
Population-base specifications: small populations
We’re asking what data tables and analysis you need for small populations. Our initial proposal is to produce
tables equivalent to those published in 2011.
17 tables for these groups:
• National identity - Cornish
• Ethnic group - Kashmiri
• Ethnic group - Nepalese
• Ethnic group - Sikh
• Religion - Ravidassia
• Religion – Jain
For Census 2021 outputs, we are defining Sikh
and Jain using both religion and ethnic group.
Local-authority-level tables by five-year age bands
by sex, for 30 other population groups defined by:
• Ethnic group
• Country of birth
We are asking about users’ needs for:
• Additional small populations, defined based
on one or multiple variables
• Further detail on small populations data that
was produced from the 2011 Census
www.sli.do 820387

27. 27
Taking a census during a period
of change
• We want to help answer the most important questions
facing society today
• We need to understand the impact the current period of
societal change has had on your needs for:
• Place of residence data
• Economic activity and employment data
• Travel to work data
• Workplace zones (geography)
• Migration, health, unpaid care etc…
• Impacts may include new, changed or reprioritised needs
www.sli.do 820387

28. 28
Paradata

information was collected
• We will consult your needs for detailed
information on:
• Household response rates
• Individual response rates
• Mode of response
• Language of response in Wales,
whether it was in English or Welsh

How we will evaluate your feedback
• We will use the information you provide to:
• identify any new or changed data needs
• prioritise the development of proposed outputs products
• finalise our release schedule and prospectus
• develop plans to supplement Census 2021 data
• The evaluation will seek to balance:
• The strength of need for the requested census data
• How publication of the requested data will serve the public good
• Other considerations, such data quality, disclosure control and cost
www.sli.do 820387

31. 31
Serving the public good
The purpose to which the data will be put is central to the
evaluation process. Purposes include:
• resource allocation
• service planning
• policy evaluation
• diversity monitoring
Implications if the requested data are not produced are also
important. Implications include:
• increased financial costs
• reduced quality of data used in decision making
• not meeting legislative requirements
