Statistics NZ’s experience in usingAdministrative Data in an Integrated
Programme of Economic
Vince GalvinGeneral Manager
Strategy & Communications
Scope of Presentation
• New Zealand’s system of economic measurement
• Measurement challenges and the role of administrative data
• Examples of Statistics New Zealand’s use of administrative data

businesses/households
Statistical Surveys
Sustainable Development Indicators
Other Satellite Accounts

The New Zealand System of Economic Statistics
Significant Issues
• Quality Issues- “Tired” Designs- Needed Integration not “designed in”
• Data Gaps• Capturing structural economic changes effectively • Growing demand from other users
– Sub populations, cross cutting topics– Financial position– Linking financial performance with business behaviour
• Manage Respondent Burden– Reduction, Communication, Taking advantage of new
technology
What might the future look like• Small Businesses monitored by administrative data
• Administrative data used to monitor populations, provide core data across the economy for all units and provide essential size measures for sample surveys.
• Sample surveys focus on complex data for large businesses
• Data integration studies to meet detailed analysis needs.
Key idea is that the administrative data goes from beinga useful data source to the population definer and majorsource.
Reasons for Pursuing this idea in NZ
• Characteristics of Administrative data well matched to population management purposes if we can integrate multiple sources
• Tax data has value as a “measurement foundation” across industries. Small businesses are simple entities.
• We have had considerable success in compiling integrated data sets.
The Potential Contribution of Administrative Data• Key challenge to manage information about business
population dynamics.
– Measurement done consistently across industries – Size and Industry up to date– Trace the status of key assets– Sub population membership
• Tax data in conjunction with other sources
– Can trace dynamics of population but can’t provide detailed data on large complex businesses
– Can provide core data across the economy

Value beyond Survey Data• Linked Employee/Employer database (LEED)
– Understanding dynamics of labour market– Contribution to Statistical Infrastructure
(geography in business frame, BF structures)
• Longitudinal Business Frame (LBF)
– More detailed understanding of the Demography of the business population
But of course……….• The main challenge is identifying a map of the key
needs and their implications for the relationships between data sources. Having a serious look at the annual economic collection as a “hub” – Pilot study of how to design links between annual financial
performance data and business behaviour data.– Rationalising the quarterly collection strategy– Annual Economic Survey relationship to quarterly
collections.– Reconsideration of how we use the random number line to
minimise sample overlap – Relationship between Commodity information and financial
information.
Example 1: The Business Frame
• Range of Improvements implemented– Updated size measures, link to population metadata, use of
wide range of tax data as “triggers”• Considerable benefits
– Reduction in birth timeliness lag, timeliness of size measure updates, reduced direct surveying, improved population analysis
• Process has enabled introducing new administrative data
• The business frame becomes a centre of “concordance management”
• Investing in Business Frame Improvements opens the way for the widespread use of administrative data

Example 2: The Use of Administrative Data in Survey Design• Estimating economic variables from Tax data
– Projecting values in the Retail Trade Monthly Survey– Modeling Quarterly Information– Annual Financial data
• Confronting high level aggregates• Compliance Cost Reductions• Improving Methods
– Assigning priorities in non-response follow up– Improved imputation
• Producing Regional Indicator information
The main question is now how the availability of dataand our information system improvements shouldchange the shape of our survey collection programme.

REDUCTION IN BUSINESS COMPLIANCE COSTS DUE TO THE USE OF TAX DATA
Example 3: The Agricultural Census
• Resumed after a gap of 7 years• Considerable discussion as to how to construct a
frame• Decision taken to use the same approach
– Standard approach helps put units into a slot across the whole frame, using other sources to check coverage
– Better to take a frame that “over covers” than “under covers”
– A set of operational “scope and coverage” rules had to be constructed to provide practical ways of bridging the gap between concepts and limitations
To be Continued…………..
• The extent to which the collection programme can be re-shaped is being considered.
• Information demands increase, compliance cost concerns still significant
• The increased use of administrative data in individual surveys has provided a useful set of experiences in terms of understanding the uses to which administrative data can be put in terms within our current framework
• The uses have highlighted that it is sensible to consider going further in basing our collection strategy around administrative data. Attitude has been surprisingly important.
• The investment in the Business Frame and success with data integration projects had put some of the infrastructure in place which has created options.
