“Less than 5 books” includes 0 books? Otherwise those stats are hard to believe.
In that case every country would add up to 100%, since the top category is “10 books or more”.
“who have read books”
Not even a quantity, but just “books”. That means that an european average of nearly half the people do not read a single book in a year?
This is so foreign to me, I have trouble to comprehend.
It is even worse:
Between 20-25% of the European population is functionally illiterate. In other words: at least one citizen in five does not have the reading and writing skills they need for functioning in society, with all its consequences for education, employment, health care, welfare, social integration and political participation. ‘More than 73 million adults in the EU… do not have sufficient literacy levels to cope with the daily requirements of personal, social, and economic life’

So they are not just not reading any books, they literally can’t read books.
I could not find info on how they get to 20-25% functionally illiterate. That seems way too high. 17% for Germany. Do you know how they define illiterate?
