Aim of project
• To assess the feasibility of having an alternative to a traditional census – a decision is required in 2014
• To explore potential of improving the quality of inter-censal population statistics
National Records of Scotlandpreserving the past; recording the present; informing the future
Background• Census
– conducted only every 10 years– costs about £65m– increased mobility of the population– response rates to surveys are dropping

McLelland Review
‘Although sensitive to information protection and privacy issues, the citizen would expect that public bodies will share and move information across internal boundaries, particularly where there is an advantage to the citizen or the community when this happens’

Challenges in using admin data• Coverage : gaps, duplication
• Definitions, geographical scope
• Timing, currency
• Breadth of information
• Quality (completeness, accuracy, consistency)
National Records of Scotlandpreserving the past; recording the present; informing the future
Sources of admin data• School Census• Child Benefit• DWP State Pension Age Benefits• NHS central Register and Community health Index• Council Tax systems• DWP Other Benefits• Electoral Register• Higher Education Student Record (HESA)• National Insurance Recording System (NIRS)• One Scotland Gazeteer (OSG)• Local Data Sources

Examples of comparisons with record level data

Linking NHSCR records to HESA recordsto identify Scottish students studying in E&W
• NHSCR – 665,000 people born between 1984 and 1990 (and hence of student age in 2007/9)
• HESA – 6,909 students born between 1984 and 1990 and with either a non-Scottish term time post code or none at all
• HESA data needed careful processing to distinguish between students located in England/Wales and those doing distance learning courses
• Of the HESA records, 6,534 (94.6%) were confidently linked to the NHSCR file
• Those who could not be linked were more likely to be of non-GB nationality (12% vs 4%) and non-white ethnicity (19% vs 10%)
• Using only linked records for students following first degrees and for whom complete data is available leaves 3,893 records.

Potentially useful LA data?• School census (including names)
• Housing benefit
• Landlord register
• Houses in Multiple Occupation
• Council tax
National Records of Scotlandpreserving the past; recording the present; informing the future
Benefits• To enable a feasibility study to inform requirement for legal
change• To help improve population and migration estimates thus
improving resource allocation• To help identify potential data sources• To help identify any data issues in terms of coverage, definitions
etc.• To learn more about the uses to which administrative data might
be put both within NRS and Councils• To facilitate sharing of information and joint working between
departments within Councils• To help improve the accuracy of the council data• To reduce the data burden on users by synchronising databases• To allow processes to be rehearsed for creating a population
spine using the census
National Records of Scotlandpreserving the past; recording the present; informing the future
Safeguards• NRS is ‘trusted’ and ‘gold standard’
• NRS work under census legislation – all data would be protected to an equivalent standard
• NRS has considerable expertise in securely transporting and storing large amounts of personal data and in producing anonymised statistics (e.g. SLS, SHELS)
National Records of Scotlandpreserving the past; recording the present; informing the future
Data Protection issues
• Legal framework is complex and overlapping
• No single source of law that regulates public sector data sharing
• First step is for LAs to determine whether they have vires for data sharing
• Use codes of practice to help ensure good practice
National Records of Scotlandpreserving the past; recording the present; informing the future
• Purposes for sharing data – statistical– Necessary for the exercise of function
conferred on RG
• Fair processing– Privacy notice requirement?– How should notice be given?
National Records of Scotlandpreserving the past; recording the present; informing the future
Proposed way forward?• Do nothing
– Miss opportunity to make use of 2011 census as a benchmark
• Step up research to integrate existing sources– Enable a decision about census alternatives
to be made in 2014– Improve quality of data
National Records of Scotlandpreserving the past; recording the present; informing the future
Questions• What are the key barriers?
• What steps do we need to take to enable data to be shared and to ensure fair processing?
• What would give greater reassurance to data controllers?
• How can we best work together?
