Census 2011 Output Content and User

ConsultationJoe Traynor

Aims

• Describe the relationships between today’s individual presentations

• Explain the consultation process in relation to particular topics and their inter-dependencies

Overview of Consultation Process

• This is the start of the consultation on outputs

• Census 2011 outputs– Taking on board lessons learned and

suggestions from 2001– Incorporating methodological and

technological innovation

Consultation by TopicGeography

Current Position•OA stability•OA alignment with Scotland

Challenge•OA re-design of statistical zones: maintain stability while addressing design problems with worst-performing OAs

ConsultationTopic•Stability vs re-designTimeframe•Nov 2009 – March 2010Process•Users will be invited to identify worst-performing OAs via website•ONS Geography to evaluate the submissions and assess performance against need for stability

Consultation by Topic contd

Dissemination

Current Position•Ability to produce outputs for a range of population bases

Challenge•Defining different possible population bases and the outputs that relate to them e.g. second residency base

ConsultationTopic•Requirement for multiple population basesTimeframe•Spring 2010Process•ONS to define baseline set of requirements•Users invited to comment via website

Disclosure Control and Geography

Current Position•Misalignment of OAs with administrative boundaries

Challenge•Two exact fit geographies desired (OA and Ward)•Comparability with 2001 vs flexibility

ConsultationTopic•Exact fit or best fit to OATimeframe•During next six monthsProcess•Report on whether record-swapping can enable an exact fit solution to be delivered via website


Disclosure Control and Dissemination

Current Position•Assume (for now) the same level of detail will be available as in 2001 – without additivity or consistency problems

Challenge•Ensure user requirements are met, while providing sufficient disclosure control

ConsultationTopic•Users’ requirementsTimeframe•Nov / Dec 2009 – Spring 2010Process•Direct consultation•Iterative process•Evaluation & prioritisation•Further details in next presentation



Disclosure Control, Geography and Dissemination

Current Position•Potential to release standard tables and/or hypercube access to data

Challenge•Balancing technology against utility, detail and flexibility for the delivery of 2011 census data

ConsultationTopic•Users’ requirements & preferencesTimeframe•Internal research is ongoing•External consultation to begin by end of 2009Process•Offer users a variety of choices, based on possible delivery channels•Consult via website with examples of range of products

Conclusions

1. Tables will be internally additive

2. Inter-table consistency

3. More information will be available

4. 2001-2011 comparability is a high priorityi. Stable geography (bearing in mind worst cases of

unfit statistical zones)

ii. Awareness, analysis and mitigation of the impact of question and response-category changes

Census 2011 Future consultation – statistical

output specification

Introduction

• Define statistical outputs of the 2011 census:– 2001 paper-based iterative approach– 2011 web-based iterative approach– More detailed definitions

Definition of output content

1. Clearly define the specification for tabular outputs that will be produced directly or via hypercubes

2. Specification will define relationships between 2001 and 2011

3. Define the geography at which the outputs will be produced

4. Specification independent of output media (hypercubes and/or tabular outputs)

5. Allow for easy amendment/redefinition of specification in line with user needs

Issues relating to defining output content

Three central issues:

1. Geographical base undecided (one base or two)

2. Dissemination media are not confirmed

3. Disclosure control

Issues relating to Geography

• Decision on one geographical base or two will not affect the definition of output content

• Tables will be defined on both OA and administrative geographies irrespective of whether an exact or best fit solution is applied

• If differencing is an issue then a best fit solution will be applied and no tables on an exact fit will be produced

Issues relating to Dissemination Media

• The development of the documentation used to consult users on the specification of outputs will allow for the production of either hypercubes or tables

Timetable consultation on tabular outputs

DATE Development of output specifications

2009 July/AugustONS develop a set of baseline set of specifications on a sub set of 2001 tables Complete

2009 August/SeptemberONS develop comprehensive set of specifications using topic group leads

Nearing completion

2009 OctoberCOWG review specifications arrive at agreed baseline set of definitions Initiated

2009 October Output events on all topics affecting outputs Initiated

2009 November/December Consult all users using the baseline definitions -

2010 January/February Refine definitions -

2010 March2nd round of consultations using redefined set of specifications -

2010 April Refine specifications -

2010 MayDefine agreed set of specifications to be produced -
