detailed statistical
information.
Metadata,
paradata,
microdata”

datasets and corresponding metadata

European statistics should be presented in a
clear and understandable form, disseminated in
a suitable and convenient manner, available and
accessible on an impartial basis with supporting
metadata and guidance (Code of Practice)
How to add meaning to the
“more”
More is only better if you know what the
data are – and how to use them
Custom-designed analyses are provided
Access to microdata can be allowed for
research purposes
Metadata are important for understanding
the data

We now need maps, timelines, dashboards,
bubble charts … and interactive is cooler
Map-Based Data Visualization …
