1. Working Group on Population and Housing Censuses
Luxembourg, May 2015
Item 4 of the Agenda
Publication of 2011 census data on Eurostat's online dissemination database

2. 2011 census aggregated tables on Eurostat website
Population (15)
Structure (1)
Family characteristics (2)
Employment characteristics (5)
Migration characteristics (7)
Families and households (2)
Dwellings and housing arrangement (2)

4. 2011 census aggregated tables on Eurostat website
Objectives:
Providing a rapid cross-country comparison of main census results
Reaching users that are more familiar with the "traditional" Eurostat dissemination database

5. 2011 census aggregated tables on Eurostat website
Data source: "bulk download" from selected hypercubes in the Census Hub
No further data manipulation foreseen in Eurostat production database
Changes/corrections need to be implemented in the Census Hub first
Main European aggregates will be computed at a later stage
All tables accompanied by European and national metadata

6. Additional validation layer
It was decided to add an additional validation check to these aggregated tables
The software EDIT was used for this purpose
EDIT produces a detailed validation report listing all problematic cells
Countries having problematic tables were asked either to correct the problems or to provide explanations
The publication of problematic tables was delayed

7. Additional validation layer
For all totals/subtotals in all dimensions:
Absolute difference between subtotal and sum of components smaller than 50 statistical units
Relative difference between subtotal and sum of components smaller than 0.5% of the subtotal
Subtotals flagged as "not available" while components are published
Check that some socioeconomic variables (CAS, SIE, EDU, etc.) are set to "not applicable" for persons aged less than 15

8. Outcome of additional validation
Vast majority of tables did not present any issue
In many cases the problems were due to erroneous "mappings" between national databases and the SMDX-RI module
Some countries did not respect the provision of inserting records for cells flagged "not available" (skipped records are visualised as "0")

9. Future steps
Datasets that are currently on hold will be published shortly
Only a few tables present, at this stage, problems that are considered as "blocking"
Main European aggregates will be computed at a later stage (no estimation foreseen for missing countries)
Further dissemination tools will be developed during 2015 (interactive maps, thematic publication, statistical dashboards and infographics)
