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

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
