Introduction
Slovenia is an example of change of
main census method
First step – 2002 Census
Combined method of enumeration
Register based (data on persons only)
About
10 administrative and statistical sources
have been used
Pre-printed questionnaires
10 topics entirely taken from registers (not
included in questionnaire)
Complete field enumeration (dwellings,
households, persons – only data not
available in sources)
Next step – new sources
Three main administrative sources
Persons
CPR
– available since 1986
Households
Household
Register (electronic form since 2007)
– Paper forms exit before – but not used for statistical
purposes
Dwellings

HOUSEHOLD TOPICS
Household Register (HR)
– Based on statement made by household member(s)
DWELLING TOPICS
Real Estate Register (RER)
– Will be also used for taxation in the future
Identificators: SID and BA_DN
Household Register
Relevant data
The main advantage
Dwelling number (DN) (running number in the scope of
address - BA) - also in RER and CPR
Household number (HN) (running number in the scope
of address - BA) - only in HR
Relation to the reference person of household
Possibility of direct derivation of household composition /
type of family for the most persons
Housekeeping concept
Data integration - input

Households quality assessment
Administrative obstacles
Legislation
Household data only for permanent residence
Statistical concepts versus administrative ones
Definition of usual residence
No data on collective households
Inconsistency of source data
Relation to reference person and age
Relation to reference person and marital status
Incompleteness of source data
Missing data on dwelling number
Households quality assessment
Statistical obstacles
Recently established source
Complexity of relations in households
Not used for statistical purposes yet
Multi-family households
Comparability of the results to previous
censuses or current field surveys
New concept/definition of household
Underestimation of consensual unions
‘’Broken’’ households
No reference person
Reference person is under certain age
Results of test database
Direct derivation of household/family
types
Simple rules – 80 %
Complex criteria – 6 %
Reasons for non-derivation
Records without household number – 4 %
Records without relation to RP – 2 %
Records with unknown relation to RP – 7 %
Fault records - only 1 %
Improvement of the process
Introduction of quality indicators
Measuring every change of input data
Use of statistical methods
Setting up households
Distinguish institutional households
Consensual unions
Conclusion
Structural changes of size of household
and types of families are expected
Huge increase of one-person households
Focus on developing statistical methods
Improving quality in close coopeation with
administrative source
Feedback in aggregate form
Common interest
