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

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
