History / active role of the Statistical Office
• In the 1980s established 3 basic registers:
– Business Register,
– Central Population Register,
– Register of Spatial Units.
• In the 1990s turned them over to the relevant
government authorities.
 Nowadays encourages to establish new
administrative registers:
– Register of Secondary Education,
– Centralised Register of Tertiary Education.

History / active role of the Statistical Office
• Encouraged the use of other administrative
sources:
– Comparisons between the data from administrative
sources and Household Budget Survey;
 Quality of administrative data were promising.
• Increased use in:
– Business statistics,
– Agricultural census,
– Social statistics – EU-SILC, Register-based Census,..
 Approximately 50 different administrative
sources are used for statistical purposes.

Use for the Economic statistics
• Short-term business statistics:
– VAT declarations for the estimation of turnover from 2007 substantial decrease of the response burden, only 5% report
also with questionnaire;
• Structural business statistics:
– almost entirely rely on annual accounting statements, only the
investment survey is conducted;
• National accounts:
– annual accounting statements, income tax declarations and VAT
declarations are used to estimate approximately 80% of the total
value added;
• Branch statistical surveys:
– employment figures are obtained from the Statistical Register of
Employment - the special employment survey was eliminated,
deletion of questions on the number of employees in all branch
statistical surveys.

Use for the Social statistics
• EU-SILC:
– 10 administrative sources: Income tax, Social
Assistance, Family Allowances, Pensions,…;
 Interview lasts only 30 minutes.
• Register-based census 2011:
– 4 core sources: Central Population Register,
Household Register (Ministry of the Interior); Real
Estate Register (Surveying and Mapping Authority);
Statistical Register of Employment;
– 6 statistical surveys;
– 6 other administrative sources;
 14 mio EUR savings in state budget, elimination of
response burden.

Benefits and weakness of administrative sources
• Benefits:
– Reduction of the response burden;
– Quality – the statistical process could be unified and
controlled by the same rules in all stages and the
subjective influence on data is prevented;
– Savings – for the field collections.
• Weaknesses:
– Definitions of variables are not always in line with the
statistical definitions – more methodological work is
needed;
– Data from different sources are not available at the
same time – complex integration.

Intensified use of statistical methods
• Administrative sources usually use different
concepts and definitions:
– Several methodological solutions have to be prepared
to put them in line with the statistical definitions –
some examples;
 Shifting the work load in the preparatory phase;
 Some statistical surveys are needed anyway, limited
in number and content. Administrative data sources
thus cannot always fully replace classical statistical
surveys.

Legal basis
• National Statistics Act:
– Administrative register must make use of valid
standards (e.g. classifications which are national
standard, unique identifications of persons and
businesses);
– The right to obtain individual data from all existing
records and the permission to link them.
• Regulation on European Statistics 223/2009
• Agreements with the owners of administrative sources
are recommended.

Agreements
• Agreements in order to:
– Assure the regular transmission of data, irrespective
of the changes in the government (minister,
responsible person);
– Clarify what, when, who transmit the data – protocol;
– Raise the awareness of the owners to consult the
statistical office before any potential changes in the
administrative source.
 The role of Director-General – to lead the most delicate
negotiations with the most challenging institutions (tax,
agriculture,…).

Close co-operation
• With the owners of the administrative sources in order to:
– Highlight the importance of the reuse of data for the statistical
purposes;
– Make clear that the transmission of individual data cold be
done only in one direction;
– Get their interest to improve the quality of data – some examples
(dwelling number, relationship to the head of household,…);
• Within the government in order to:
– Encourage the establishment of the new administrative registers
– i.e. Real Estate Register, Household Register;
 Through e-government and statistical advisory committees.

Adaptation of existing statistical process
• Centralized one point for the acceptance of
administrative sources;
• Creation of the list of administrative registers with
correspondent persons responsible for the content,
technical issues;
• Issues of confidentiality – controlled access to individual
data, personal identification number transformed into
statistical number;
• Sources should be checked and edited before any
integration – administrative sources are not perfect;
• Linkage of data at the micro level, priority of sources,
imputations, sometimes manual editing.

Different and additional knowledge is needed
• Project team for the most complex integration, i.e.
Register-based Census, Agricultural Census;
• Small team of persons (approximately 10) with different
knowledge;
• Dedicated project leader;
• High level support to the team;
• Regular reporting (monthly);
• Methodological meetings (mixed levels, knowledge) to
approve some methodological issues (to harmonise
approaches).

Future challenges
• Undesirable changes or abolishment of administrative
sources due to the reduction of administrative burden by
different institutions;
 More coordination and co-operation with different
institutions are needed:
– Possible solution: an appropriate legal framework that
establishes the control rights of the NSI (e.g. the need to consult
the NSI before changing any of the features of the administrative
data;
– SORS developed mechanisms for coordination through:
• Statistical Advisory Committees;
• E-government.

To sum up
• High-level political support;
• Legal basis, plus agreements with the owners;
• Active role of the statistical office and its DG in
encouraging the establishment of new registers, their
maintenance (improving quality) and in preventing of
undesirable changes or even their abolishment;
• Administrative sources might give even better data,
reduce respondent burden and decrease costs (for
field collections), however,
• more methodological work is needed; the work load is
shifted in the preparatory phase, burden is shifted to
the NSI, additional knowledge is needed, motivated
staff with high level support;
• Adaptation of existing statistical process.
