Advantages of a register-based census method
Fieldwork is not necessary,
so the number of people participating in the register-based population census is
much smaller. For example, more than 10,000 people participated in the 2002
Census.
No respondent burden
with questions for data that have already been sent to other state authorities
or for other statistical surveys.
Significant budget savings.
With a registered-based
census we estimate EUR 10 million of state budget savings. The costs of the
registered-based census present only 10% of the costs of the classical fieldwork
census.
No additional employment.
Only
statisticians–methodologists and IT experts participate in the implementation of
the census.
Data quality.
It is possible to provide a uniform and controlled methodological approach in
all stages of the process.
Data processing time is
shorter because the input data
sources are previously regulated, so the data may be available to users sooner.
Registered-based census can
be carried out more frequently than every 10 years, as in
the previous fieldwork censuses. Modern societies are changing rapidly, and
users need up-to-date and current data.
Restrictions
of a register-based census method
Dependence
on existing sources, their content and quality of the data. The Statistical
Office has no influence on the management of the administrative sources; in
addition, the management methodology is adapted to the administrative needs.
Mismatch
of the same type of content and data from different sources (due to different
time sections of data collection, methodology, updating).
Unavailability
of administrative data sources. So far, in Slovenia
various public opinion data were collected with fieldwork census (e.g.
ethnicity, religion, way of travel to work), which will no longer be the topic
in the Register-based Census 2011.
Insufficient
data in some administrative sources, as the managers need some time to gather
and process the data. This also increases the time of preparing the data for
individual topics of a register-based census.
