The Use of Administrative
Sources for Statistical Purposes
Administrative
Sources and
Statistical Registers
Direct Use
• Simplest case - an administrative
source is used directly as a sampling
frame
• Easy and cheap
• Quality problems?
• Lack of control?
Indirect use (1)
• One or more administrative sources
are used to construct a statistical
register
• A statistical register can be a tool
for integrating data from different
sources
Indirect use (2)
• A statistical register can contain
additional variables, e.g. from
surveys, imputed, or calculated
• The statistical register is owned
and controlled by statisticians
Multiple data sources
• Data from a single source
– no check on accuracy
• Data from several sources
– better view of the accuracy of the data
– increased range of variables available
– but; how to deal with data conflicts?

and Maintaining

Basic Registers in Sweden
Central Register
Cross-government projects to create
central registers of person / business
data to facilitate data sharing, e.g.
• Registers in Nordic Countries
• Australian Business Register
• UK Business Index
Case Study - ABR
• The Australian Business Register
(ABR) is developed and maintained
by the Australian Tax Office
• Web interface (www.abr.gov.au)
• Businesses can register, amend
details and file returns on line
• Free access for Australian Bureau
of Statistics
Case Study - ABR (2)
• The Australian Bureau of Statistics has
a two-tier statistical business register
– Most records are direct copies from the
ABR
– Only the largest and most complex
business structures are maintained by the
statistical office
• This allows statistical resources to be
used where they are most needed
Case Study - UK
Business Index
• New project to create a basic central
register of businesses
• Partners:
– Office for National Statistics
– Tax office
– Company registration agency
– Local authorities
– Specialist agencies e.g. environment,
health and safety
Business Index Model
Using Administrative
Data in Satellite
Registers
What is a satellite
register?
The Eurostat Task Force on satellite
registers on distributive trade said:A satellite register is a register of units
which belongs to the national statistical
system, and fulfils the following
conditions:
1. Satellite registers are not part of
main statistical registers, but are
closely linked to them;
2. Satellite registers are more limited
in scope than main statistical
registers, but within their scope they
may have better coverage;
3. Satellite registers contain one or
more characteristics that are not
found in main statistical registers,
especially stratification variables;
4. Satellite registers should be
distinguished from those databases in
which results from surveys are
normally recorded
So a satellite register is a tool for
incorporating administrative data that
are only relevant for a sub-set of units
in a statistical register
Satellite registers
Satellite
may contain
additional units, Register
or variables, or
both
Statistical
Register
Examples in Practice
• Tourism - hotel register (category,
number of beds)
• Transport - vehicle or ship register
(type, capacity)
• Distributive trades - buildings register
(building size, sales area)
• Military personnel – register of people
serving in the armed forces
Purposes of Satellite
Registers (1)
• Constructing more comprehensive
sampling frames
• Extending coverage of target
populations
• Providing additional stratification
variables
• Providing auxiliary variables to help
estimate population totals
Purposes of Satellite
Registers (2)
• Providing variables that can
supplement or replace those collected
through surveys
• Improving the quality of information
already in the main register, therefore
reducing costs and the response
burden

Entrepreneurs
Case Study:
Statistical Business
Registers in the
European Union
Background (1)
• EU Regulation (2186/93) - Business
registers for statistical purposes are
compulsory in all EU Member States
• The Regulation lists compulsory and
optional variables
• The latest version includes enterprise
group variables
Background (2)
• It is unlikely that all variables are
available from one source, so
multiple sources are needed
• The use of administrative sources
is encouraged
• The choice of sources is left to
Member States
Background (3)
• Eurostat collect information on
sources used and data quality via an
annual questionnaire
• The UNECE sends the same
questionnaire to countries that are
not members of the European Union
