The “European Census 2011” challenge UN’s Economic and Social Council’s resolution 2005/13:
urging countries for population and housing census between 2005 and 2014
Regulation (EC) No 763/2008 of the European Parliament: 2011 European Census
Required: Unprecedented level of detail and volume of data Comparable results for 32 countries Dissemination of census results in a timely manner
2
EU Member States and EFTA countries collect micro data: 37 statistical variables 4 main areas:
persons, housing units, private households, families Using a variety of data collection methods From different sources At different times
… to disseminate results (macro data): At level of municipality
(Geographical granularity ± 130 000 units) Grouped in 95 hypercubes (60 data / 35 metadata)
The “European Census 2011” challenge

What did we need? Environment
• to disseminate massive amounts of harmonised data • which is easy to use (and reuse)
Single point to access • census results for 32 NSIs• numerical and textual metadata
Possibility to compare and cross-tabulate Availability from 31st March 2014 until 2025
Not required:Validation or aggregation on the fly
4
What is the European Census Hub ?The project:- Interoperability initiative with 32 countries participating- Business driven
The technical solution – Hub architecture: Single information system to query and visualise data for 32
countries Framework to expose in a unified format statistical data
stored in multiple dissemination databases

Challenges and potential for the future
Data availability depends on country node availability Response time slower than with a central DB 32 DBs to be kept until 2025
Synchronising in a centralised database ?
Some basic data derivation could be implemented
8
As of today, the European Census Hub offers …
User interface to extract data using statistical variables as data filters
Most up-to-date results
Portal for data dissemination based on SDMX Reusable components Universal modules for data exchange via SDMX Web Service
… Census 2011 results for 29 countries9
Thank you for your attention
