National Statistics designation
The United Kingdom Statistics Authority has designated 2011 Census statistics as National Statistics, in accordance with the Statistics and Registration Service Act 2007 and signifying compliance with the Code of Practice for Official Statistics. Designation can be broadly interpreted to mean that the statistics:
meet identified user needs;
are well explained and readily accessible;
are produced according to sound methods, and
are managed impartially and objectively in the public interest.
Once statistics have been designated as National Statistics it is a statutory requirement that the Code of
Practice shall continue to be observed.

The 2011 Census Prospectus: Introduction
This prospectus sets out the release plans for forthcoming statistics from the 2011 Census in England
and Wales. It describes the intended publishing schedule, and outlines the statistics that the Office
for National Statistics (ONS) is publishing. It also includes details for combined UK releases.
Statistics already published
Statistics already published are detailed in the 2011 Census Catalogue, and are summarised here:
http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/previous-and-future-
releases/index.html
The comprehensive census glossary explains terms contained in the prospectus and in census
releases.
Scotland, Northern Ireland and UK Simultaneous but separate censuses took place in Scotland, run by National Records of
Scotland (NRS), and Northern Ireland, run by Northern Ireland Statistics and Research Agency
(NISRA). NRS’s and NISRA’s prospectuses are available via their respective websites.
ONS is also responsible for the publication of UK statistics (compiling comparable statistics from the
UK statistical agencies above). This prospectus covers the publication of UK statistics.
UK statistics published to date are available here:
http://www.ons.gov.uk/ons/guide-method/census/2011/uk-census/index.html

Release stages for 2011 Census statistics
Because of the breadth and depth of the 2011 Census results, the statistics are being released in four
stages. Each stage will comprise several separate releases of statistics.
First release stage: 16 July – November 2012 Age and sex, and occupied households estimates for England and for Wales.
Information about second addresses by age, sex, and type of second address.
See data catalogue for releases
Second release stage: 11 December 2012 – March 2013 Key and Quick statistics, and postcode estimates.
See data catalogue for releases
Third release stage: May 2013 – March 2014 Detailed Characteristics
Fourth release stage: July 2013 – September 2014 Local Characteristics. Fifth release stage: October 2013 onwards Alternative population bases. Specialist products: November 2013 onwards Specialist products, such as origin-destination data, microdata and small population groups.
Included with the statistics
1. Commentary, in the form of a statistical bulletin, appears alongside every major release,
providing:
description and context around each topic,
comparability to the 2001 Census outputs,
updates to the user guide, and
further sources of information where applicable.
2. Reference material is updated for each release, including definitions of terms and concepts.
3. ONS data visualisations provide an easily accessible way to identify key changes and
compare results across geography and/or through time.
6
Tables and layouts subject to change
The planned tables and layouts may be subject to change or redesign before release, to better fulfil
user requirements, for data quality issues, or as a result of statistical disclosure control.
Restriction of detail as a result of statistical disclosure control
The 2011 Census provides rich detailed statistics at many levels of geography. However, the depth of
detail (that is, the number of potentially attributable characteristics) supplied at output area level
will understandably be lower than at higher geographical area levels in order to protect individuals
and households. This restriction on the level of detail of output variables is the second part of the
statistical disclosure control strategy (with targeted record swapping being the first).
All statistics, including Quick Statistics (formerly univariate tables), will be subject to review prior to
their release. ONS reserves the right to amend any of the proposed tables at any stage of the 2011
Census statistics releases due to, for example, statistical disclosure control or data quality concerns.

13
Subsequent releases of 2011 Census specialist products
This section outlines the plans for these statistics not included in the main release phases:
small population groups,
microdata,
origin-destination data,
alternative population bases including: workday, workplace, and majority of time.
Small population groups
By their nature small population groups are difficult populations to publish data about because their
confidentiality must be protected.
To avoid disclosure, that is to ensure that members of the population group cannot be identified
from our census data, ONS has set a threshold of 50 people per middle layer super output area
(MSOA). MSOAs have at least 1,000 usual residents and 400 households. Tables for a small
population will only be produced if there are 50 or more qualifying people in the given MSOA
geography.
Release 6.2: Armed Forces Statistics for Local Authorities in England and Wales
Release: Small population table for England and Wales
Microdata
ONS is aware of the importance to users of samples of anonymised records (SARs) and is confident
that fit-for-purpose, appropriately accessible UK microdata files will be made available in 2013.
Three levels of microdata are planned for 2011 Census:
Teaching file
The teaching file is now available from the ONS website. Published on 23 January 2014
Formerly known as the public use file, the primary aim of the teaching file is as an educational tool.
The release of this non-disclosive, individual-level file is in line with the government transparency
agenda. It is less detailed than the file made available under end-user licence in 2001, with a 1 per
cent sample of individuals.
Safeguarded files
One type of safeguarded file will be at the individual person level, and it is intended that this will be
made available to users, subject to approval, via their desktops under strict terms and conditions.
(More information about these terms and conditions and how to obtain access to the file will be
made available shortly.) The file is likely to contain a similar level of detail to the 2001 small area
microdata, and the individual level SAR, with a maximum sample size of 5 per cent. ONS hopes to
14
have this file ready for release in September 2014, however, this date is currently provisional and is
subject to change.
ONS is also looking at the feasibility of releasing household hierarchical data containing records for
all individuals, within a sample of households. Further information on the results of this work will be
made available in late summer 2014.
All files will be subject to being able to apply sufficient disclosure control.
Secure files
In the long term, these anonymised data will be held in a secure environment, ONS’s Virtual
Microdata Laboratory (VML). However ONS is currently working on a project to replace the VML and
options for how the secure microdata files can be made available before the new VML is launched,
likely to be towards the end of 2014, are being investigated.
The files will generally be similar to the 2001 Controlled Access Microdata Sample (CAMS), both
household and individual, and will contain a maximum sample size of 10 per cent. To see the
planned microdata product table, download proposed 2011 microdata products.
Planned features include microdata sets with sample sizes larger than previous censuses, the
opportunity for exploratory analysis on rich and flexible datasets, the opportunity to test outputs
before requesting commissioned tables, and the ability to perform multivariate statistical analysis,
all using records that are comparable with the standard census outputs, since they have the same
source.
The household and individual secure files are planned for release in August 2014, however, this date
is not yet confirmed and is dependent on the availability of a secure environment in which to store
the files.
Origin-Destination (flow) data
Origin-destination data (also known as flow data) include the travel-to-work and migration patterns
of individuals, cross-tabulated by variables of interest (for example occupation). New products for
the 2011 Census also provide the migration patterns of those living at a student address one year
ago and will provide information on individuals with second residences.
Release: Origin-destination statistics on migration, workplace and students for local
authorities in the United Kingdom
Release: Origin-destination statistics on second residences and workplace for merged local
authorities and middle layer super output areas (MSOAs) in England and Wales
Release: Origin-destination statistics on migration for local authorities in the UK
15
Disclosure control
All population estimates, including small estimates, will be permitted in principle. However, ONS has
an obligation to protect the attributes of identified individuals and may revise table designs if they
are deemed disclosive on completion.
The UK Statistical Disclosure Control policy states that the protection of the most detailed origin-
destination tables will come from the licensing/access conditions. This is a change from the 2001
Census, where the protection for similar outputs came from the post-tabular small cell adjustment
which still allowed wide and easy access, but also adversely affected the utility of the outputs.
For more information on the statistical disclosure control policy for origin-destination tables, please
read section 8 of the Statistical disclosure control for 2011 Census.
Access conditions
There will be a small number of tables that are available publicly, however, the majority will only be
available as secure files under certain access conditions.
The more detailed tables and those at lower levels of geography will only be available as secure data
within a secure environment. The secure data will be held in ONS's Virtual Microdata Laboratory
(VML) in the long term, however ONS are currently working on a project to replace the VML and
options for how the secure origin-destination data can be made available before the new VML is
launched, likely to be towards the end of 2014, are being investigated.
The VML is only available for research purposes conducted by an Approved Researcher. Read about
how to be accepted as an Approved Researcher.
ONS cannot yet accept requests for access to origin-destination data. We will provide more
information on how to do this closer to the time of release.
For those who do not wish or need to visit the VML but still have an interest in the origin-destination
data, some of the less detailed tables will be treated as safeguarded files and made available to
researchers to hold outside of ONS under strict terms and conditions. More information about these
terms and conditions and how to obtain access to the tables will be made available shortly.
Table specifications for all origin-destination tables are available; see Flow data table layouts. These
specifications provide confirmation of the geographies that will apply to each table, as well as a
provisional indication of whether each table will be public, safeguarded or secure. However, this is
only a provisional indication and each dataset will have to be assessed for disclosure before a final
decision on the access channel is made. It is possible that some of the tables indicated as being
secure may be able to be made available via the safeguarded channel.
16
Publication
The first batch of origin-destination tables was released on 25 July 2014. There were two releases:
1. Origin-destination statistics on migration, workplace and students for local authorities in the
United Kingdom, and
2. Origin-destination statistics on second residences and workplace for merged local authorities and
middle layer super output areas (MSOAs) in England and Wales.
To see these releases, select the Origin-destination page from the 2011 Census data catalogue.
The UK release consists of 11 tables, all at local authority level. The scope of this release changed
from that previously announced, with only the three workplace tables covering the whole of the UK.
The other four, previously announced, tables covering migration and students are available for
England and Wales and Northern Ireland only, and do not cover the whole of the UK.
National Records for Scotland, which is responsible for the 2011 Census in Scotland, has identified an
issue with the Scottish results that needs resolving before the data can be published. The statistics
for England and Wales are provided in separate tables to the statistics for Northern Ireland, giving a
total of eight tables rather than the four tables announced previously. Tables covering the whole of
the UK will be published later in the year when this issue has been resolved, and a release date will
be published on this page when it can be confirmed.
The England and Wales release consists of nine tables (47.5 Kb Excel sheet), six at local authority
level and three at middle layer super output area (MSOA) level. This release is not affected by the
issue with the Scottish results, and was published as originally planned.
An additional 12 tables for the UK, produced at one or more levels of geography, have been
identified as priority tables, and work is currently underway to make these tables available to users
as soon as possible. Four of these tables are affected by the issue with the Scottish results, meaning
that the tables will be provided for England, Wales and Northern Ireland only in the short-term, with
full UK results published later in the year when the issue has been resolved. Again, the statistics for
England and Wales will be provided in separate tables to the statistics for Northern Ireland. In
addition, multiple geographies are published in separate tables, giving a total of 24 tables. These
tables will not be available publicly due to the level of disclosure in the tables, and instead will made
be available as either safeguarded or secure files, under access conditions.
Safeguarded tables: The safeguarded tables will be released in August 2014. As these tables will not
be available in the public domain with equal access for all, the release of these tables will not be
announced in the ONS Release Calendar. However, the release date for these tables will be
published on this page when it is confirmed, along with information on how to apply for access to
the tables.
Secure tables: Work is ongoing on an interim solution to make the secure tables available before the
new VML is launched later in 2014. The inclusion of UK migration tables in this release is dependent
on whether the issue with the Scottish results can be resolved before the interim VML solution is in
place. If not, the migration tables will be released for England, Wales and Northern Ireland only in
17
the short-term, with full UK results published later in the year when the issue has been resolved. As
with the safeguarded tables, the release of the secure tables will not be announced in the ONS
Release Calendar, but the release date will be published on this page when it is confirmed, along
with information on how to apply for access to the tables. ONS will not accept any requests for
access to this data before this time. It is expected that the approval process to gain access to the
secure data in the Virtual Microdata Laboratory will take approximately 2 weeks.
The current proposed timetable for the release of the remaining origin-destination products is for
the secure files to be made available in November 2014, and the safeguarded files to be made
available in December 2014. However, these dates are not yet confirmed and are subject to change.
It is expected that all of the tables that can be made available publicly will have been included in the
July release, (apart from those affected by the Scotland issue which we will release as soon as
possible). However, until Statistical Disclosure Control checks have been carried out on each of the
tables the release channel cannot be confirmed.
The issue found with the Scottish results also affects the:
the European Commission Census Regulation Statistics which were released in March 2014, and
the planned release of migration statistics for the UK.
Alternative population bases
These estimates will be assessed prior to release and, depending on the quality, only limited outputs
may be available, such as age by sex.
Majority-of-time: the population estimate for a given geography, to place individuals in the
household where they reside for most of the time, for example, second residences used for work
purposes.
For short-term residents, workplace population, and workday population statistics, see the fifth
release.

2011 Census data publishing strategy
The latest release from the 2011 Census is being published across ONS’s websites. This page explains why.
About ONS’s family of websites
ONS is responsible for four websites, each offering a different service:
The ONS website publishes all bulletins, and most of the data, from its releases, as well as offering background information and guidance.
Neighbourhood Statistics (NeSS) is an ONS web service specialising in the dissemination of detailed, small-area data. The NeSS website has an API.
Nomis is a web service provided by the ONS to give access to detailed UK labour market and other population statistics from official sources. This site is designed to handle complex tables.
The Publication Hub is owned by the UK Statistics Authority, and operated by ONS on behalf of the the National Statistician. It announces and links to statistical releases from across the Government Statistical Service – the statistical units from UK government departments.
Why is the latest release published only on Nomis?
Nomis is designed to handle complex statistics, including data for small areas or multivariates.
Do I have to register to use other ONS websites?
No. You do not need to register to use any of our websites. All sites are free to use.
Is Neighbourhood Statistics still a useful source of 2011 census statistics?
Yes. Although it doesn’t house complex multivariates, Neighbourhood Statistics provides a useful
source of comparative data. The NeSS ‘Census’ topic includes the 2011 Census Key and Quick
Statistics along with their 2001 equivalents. Go to NeSS topic search

New Developments for 2011 Census results
Commissioned tables
ONS will continue to provide a commissioned table service for census statistics.
Commissioned tables (from the 2011 Census) can be pre-ordered from Census Customer Services.
Commissioned tables will be constrained by the data that are available at each stage, by the
similarity to what ONS plans to release, and by statistical disclosure control.
The price list for commissioned tables (25.4 Kb Pdf) in England and Wales has now been published.
Four price bands have been identified to give customers a guide of how much their commissioned
table will cost. However the customer services team will agree the final cost with the customer prior
to any work commencing. Prices are effective from 1 June 2012.
All commissioned tables will be published on the ONS website as explorable and downloadable
datasets for all statistics users under the Open Government License.

Enhancing access to ONS data
Many other organisations have systems that provide census data to their users and this widens
access and helps increase the value derived from the information collected by the 2011 Census. ONS
is currently developing an Application Programming Interface which will provide machine to
machine access to census data for other web systems. In time, the Application Programming
Interface will also provide access to a wider range of ONS information. More information is available
from: [email protected]. See WDA pages http://www.ons.gov.uk/ons/about-ons/what-we-
do/programmes---projects/enhancing-access-to-ons-data/index.html
2011 Census geography
The 2011 Census Geography prospectus describes the release plans for the 2011 Census geography
reference data, and provides some background about how the reference data are produced and how
they should be used. These reference data include digital boundaries for the modified set of output
areas, super output areas, and the new workplace zones, and a number of supporting lookup files to
enable linkage between the 2001 and 2011 output areas, and from the 2011 output areas to the
2011 Census output geographies. Access the 2011 Census Geography Prospectus.

2011 Census User Guide
For help with terms and definitions, see the 2011 Census User Guide which contains a census
glossary, information about variables and classifications.
Pensionable age
The 2011 Census defines working age as between 16 to 64 for both men and women. The definition
of pensionable age now refers to men and women aged 65 and over. Alternate measures of
pensionable age will not be provided in the first four main stages of releasing 2011 Census statistics.
Some of the 2011 Census tables – based on those from 2001 – have been redesigned as a result of
changes to pensionable age. Information will be provided in the metadata.
Users who require alternative definitions of pensionable age can request these through the
commissioned table service. Requests for commissioned tables from the 2011 Census will be
constrained by the statistics already released, the similarity to the statistics planned, the availability
of the data, statistical disclosure control and resource availability. Commissioned tables can be pre-
ordered from Census Customer Services.
Additional information
Comments or queries about the data should be sent to Census Customer Services.

Revisions and updates
In line with ONS’s revisions and corrections policy, rigorous quality checks will take place of all
census statistics which are released. ONS may occasionally need to revise statistics and update
information.
Change notifications
In this event, users will be informed via Census News Alerts (register via
[email protected]). Updates to data will be provided to the Neighbourhood
Statistics (NeSS) website and the Nomis website teams.
Prospectus updates register
Amendments to the prospectus will be published as and when changes are made. Download the
