The graphs are meaningless. What they measure is how strict the government is at collecting unemployment figures for young people.
It simply shows 3sets of countries.:
Spain/Greece/Portugal it's presumably very easy to claim unemployment and 50% of those 50% listed are also working for cash
Italy/UK/France it's relatively harder to claim unemployment while working and most of the 15% are actually unemployed
Germany has a much smaller youth population and managed to absorb more of them in youth-training-schemes. And it got doubly lucky that birth rates fell fastest in the east where the unemployment is. It's as if in the mid80s the UK had persuaded everyone outside the M25 to stop having kids.
