Background to the (current) SHS
• Sample of general population in private
residences in Scotland
• Priority on communities, local government and
transport
• Continuous survey approx 14,000 households
– Using face-to-face CAPI, approx 45 minutes
• Consortium of Ipsos MORI and TNS-BMRB
– Fieldwork and data processing
Why the survey was commissioned
• Commissioned 1998, survey started 1999
• Devolution preparations identified need to
improve information sources in Scotland
– Information needs expected to increase
• Existing information sources limited:
– Too infrequent
– Too small a sample size
– Insufficiently detailed
Why we have aims and objectives
• Policy and parliament
• Disaggregation of
sub-groups
• Cross-analysis
• National trends
• Follow-up surveys

and local

Parliament
Why the data is needed
• Designed to provide reliable and up-to-date
information:
– Composition, characteristics, attitudes and behaviour
of Scottish households and individuals
• Supporting National Performance Framework
and wider evidence-based policy making
– Five (of the 45) National Indicators
– Neighbourhood rating, quality of public services
delivered, smoking prevalence rates, journeys to work
by public or active transport and traffic congestion
– Around one third of the Local Outcome Indicators
Why it’s used in secondary analysis
• Special dataset requests
– Glasgow-Edinburgh Collaboration Initiative Economic Linkage
– Relationship between the built environment and physical activity
in UK neighbourhoods
– Glasgow Housing Association Investment Programme: Impact
Assessment
– Healthy life expectancy
– Modelling cultural participation and inactivity
• Follow-up survey requests
– Home appreciation loans
– Bus perceptions
– Parenting in Scotland
What geographies do we cover
• No geographical exclusions, and designed to be
– Nationally representative every quarter
– Representative for larger LA’s every year
– All LA’s (regardless of size) over a two-year period
• Geographies available for analysis
–
–
–
–
National
Local Authority
Scottish Index of Multiple Deprivation
Urban Rural Classification
What sample design do we use
• Equivalent to a SRS of 500 in each LA area
• First stage disproportionate stratification by LA
• Within each LA, second stage stratification by
SG Urban Rural Classification into ‘Urban’
stratum and ‘Rural’ stratum
– Unclustered sampling in urban with addresses sorted
by SIMD
– Clustered sampling in rural with datazones used as
PSU selected with probability proportionate to size
What things we do ask
• Two part interview
– Household (Highest Income Householder)
– Adult (Randomly selected adult)
• Travel Diary
• Culture and Sport module

How the data is used to inform policy
• SHS Lead Analysts are the key
stakeholders in managing policy
requirements of the SHS
– Play the pivotal role in shaping the priorities of
the survey
– Ensuring the questions asked meet their
relevant policy needs
– Ensure subsequent analysis is best targeted
How we store the data
• Data held in SAS format
– Household | Person | Random Child | Random Adult |
Travel Diary
• SHS “libraries” available on SAS servers
– Data administration in DOSPTN
– Access permissions agreed by SHS Data Manager
and ISIS
• Also make SPSS data available on request
– Single flat file so different structure and requirements
How we describe the metadata
• Operational and procedural metadata
available via technical reports
• Definitional metadata is key though
– Topic lists and questionnaires
– Variable lookup system
How we publish “data”
• Dissemination strategy
– Increase identity, awareness and use of the
SHS
• Particular focus on
– Publications
– Access to data
– Website
How users can get data
• Published reports www.scotland.gov.uk/SHSPublications
• Scottish Neighbourhood Statistics www.sns.gov.uk
• Economic and Social Data Service website (UK Data
Archive) www.esds.ac.uk
– Two-year sweep data up to 2007/2008

Problems: Other demands
•
•
•
•
•
•
•
Strategic governance needs to be improved
Would like sub-LA and other geographies
Shows broad trends but offers little explanation
Timeliness and representativeness
Need to explore alternative survey mechanisms
Engage better with stakeholders
