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

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

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
