Would you like me to investigate the propensity of this EU wide, or are you being glib about knowing only a single country and that technically is 100% of your knowledge?
I could probably speak a little to the surrounding nordic countries to be honest, it is fair to assume they have similar systems because they are very similar in many areas.
I think making any broad EU statement even if it applies to many/most is fine.
There will always be some outliers in the data.
There is a similar argument about generalisations on behaviour, ie: statistically average behaviours of people.
You have to be able to talk in broad strokes with the knowledge that it doesn't apply to everyone.
