1. Structural analysis of the aggregate outputs from the 2011 Census to develop alternative integrated multidimensional conceptual models of data and geographies for easier management and dissemination Justin Hayes UK Data Service What the census tells us workshop Manchester 23 July 2014

2. Making it easier for everyone to find, understand and use the bits of the census they’re interested in Justin Hayes UK Data Service What the census tells us workshop Manchester 23 July 2014

3. Overview Traditional and integrated approaches Work with 2011 outputs Integrated descriptive model Integrated model of geographies Ongoing work with data producers

4. Our job Find Understand Use Automated systems with online interfaces Online and interactive support Main services now freely available to everyone

5. Traditional tabular aggregate outputs Outputs conceived and specified as tables Details of individual tables defined through consultation with different user groups Per-table categorisations and descriptions Complex table universes and footnotes Visual layout an important consideration Extended metadata unattached Complex process! Number of tables limited by resource available Numerous inconsistencies between tables Effectively separate datasets

6. Traditional tabular dissemination

8. Integrated aggregate outputs Deconstruct tables Assemble and rationalise all variables and categories in tables Variable-ise table universes and footnotes Create a standardised library of variables to describe all data Define integrated models of characteristics (What?)and geographies (Where?) Enables global operations/queries Framework for Attachment of extended metadata Facilitates description and transfer using standards Provide access via Web service API Data becomes self-describing

9. Integrated dissemination

10. Variable combination selection

12. Category combination selection

13. Area selection

15. InFuse

16. Under the bonnet Integrated multidimensional descriptive model Integrated model of geographies The really important bits!

17. InFuse 2011 release 2: Raw data England and Wales Local and Detailed Characteristics to output area level UK harmonised data to local authority level 422 tables, mainly multivariate 31 geography types 241,334 areas 11,311 files 15Gb volume

18. Integrated descriptive model Processing of raw metadata Deconstruction, rationalisation and re-integration Library of variables and categories Re-insertion of data values Attachment of associated metadata Global description using standards Global operations via Web service API Data is self-describing Enables lightweight, generic applications

19. Benefits of this work Data producers Efficient data management Flexible output production Best value Application developers Easy access to self describing web services Light weight generic applications End users Quick and easy global search Context along with data

20. InFuse 2011 release 2: Processed data 97 variables 2,501 categories 281 variable combinations 140 thousand category combinations 4.6 billion values A 460Km high stack of sticky notes! Anticipating approximately 10 billion values in all

21. Integrated model of UK census geographies Assembly of raw information on geographies 31 geography types 241,334 areas (anticipating ~ 2 million including postcodes) Direct and indirect hierarchies Simplified presentational model 11 composite geography layers Simplification of merged geographies in England and Wales Calculation of ‘missing’ data Linkage between descriptive and geography models Partial availability of data for geographies and extents

22. Raw admin and statistical geographies

24. What’s next for InFuse Interface improvements Geography first option Fine tune interface features Select categories from more than one category combination ‘Select all’ categories Back button Geography tree improvements (multiple hierarchies) User testing

25. What’s next? More data More comparable data Different data Boundary and flow data More functionality Personalisation, analysis and visualisation Public InFuse API Work with statistical agencies? Machine-friendly data from source Flexible generation with automated disclosure control? Information on usage and contact with users

26. What is the UK Data Service? a comprehensive resource funded by the ESRC a single point of access to a wide range of secondary social science data support, training and guidance

27. UK Data Service Census Support Specialist function of UK Data Service Access and support services for outputs from recent UK censuses Add value by making census outputs easy to find, understand and use Engagement with UK census agencies Long history of technological innovation in service development census.ukdataservice.ac.uk
