Slide7Census architecture - The IT Census System
For the purposes of census design and conduction, the Central
Statistical Office of Poland implemented
the IT Census System(ISS)
The ISS
integrated various technologies (from Internet data collection portal, applications installed on mobile terminals, through applications managing field works and assisting in telephone interviews, to specialist microdata bases, data

Slide10The Metainformation
Subsystem gathered indispensable metainformation describing data and census processes. The task of the Metainformation Subsystem was to ensure the coherent definition of statistical objects for the OMB and AMB.
The
Operational Micro Data Base (OMB) - system included hardware-system-tool infrastructure (computer hardware, system software, software
tools) and applications
(computer programs that are the result of programming work)
. This base
enabled the inclusion of data transmitted in electronic form through four informational channels by entities and to conduct further data processing. In the OMB there took place processes connected with the control, correction, and linking of data, up to their complete cleansing. Next, depersonalised data were transferred to the Analytical Microdata Base (AMB).

For
the
census
purposes
were
implemented
the
following
systems:
Slide11The role of the Analytical Microdata Base is to store depersonalised census data in their final form. In this dataset every type of statistical analyses is carried out to acquire results for publication, i.e. the census products. The AMB allows all the recipients of statistical information to quickly acquire data in the form of
tables, aggregates
and hypercubes
. The AMB system constitutes an analytical and reporting platform that currently enables the statistical preparation of the outcome data from the National Population and Housing Census 2011. The results of analyses in the form of documents, reports and breakdowns are shared with internal and external users. The AMB also allows the calculation of spatial analysis and aggregates available in the Geostatistics Portal as maps (cartograms and cartodiagrams).

Entering identification data in a questionnaire (PIN code – (PESEL, NIP) first name, last name) or additional authentication qualities (f.ex. a place of birth, mother’s maiden name)
Establishing a new password which jointly with PESEL was the basis of authentication within 14 days

Slide29Census organisation support systemsImplementation of
the Notification System and the Knowledge Base facilitated effective communication with all members of the census organizations
:
In the Notification System, several thematic sections, so-called projects, were created. Each project encompassed a selected thematic area.In the Knowledge Base were gathered up-to-date versions of documents, including instructions, training materials, and the operational schedule
.To ensure effective management of the remote enumerator instruction process, the m-learning application was employed. It was installed on mobile terminals
.

Slide31Summary
simultaneous data collection, without paper, from four different
channels (i.e. administrative registers, Internet self-enumeration (CAII), direct interviews conducted by census enumerators, using electronic questionnaires (CAPI), and telephone interviews conducted by statistical interviewers (CATI)) was used and implemented on such a large scale for the first time in Europe,
data from 27 administrative registers and 3 non-administrative systems were effectively integrated,paper questionnaires were completely eliminated, and were replaced by ICT solutions,
31
The census in Poland turned out to be innovative project
not only countrywide but also worldwide on grounds of the following facts and figures:
Slide32Summaryt
he use of GIS technology helped to conduct the census preparatory work and an ongoing census process monitoring and give possibility to compile and present census results based on multi-dimensional spatial analysesIT Census System comprised a number of solutions ensuring the high level of security of the processed data,
t
he modern statistical data processing technologies have been developed – they will have a considerable influence on the methodology of on going and future statistical surveys,
