Drunken girls or biased reporting

Teenage girls in UK have the highest levels of drinking according to reports of an OECD study. They do, but the OECD study also says:

'In other areas the UK performs well. Children in the United Kingdom are materially fairly well-off. Average family income is higher and child poverty is lower than OECD averages. Children in the United Kingdom also enjoy a high quality of school life. The United Kingdom ranks 4th out of 25 countries for children’s school satisfaction. Rates of bullying are also relatively low.'

But this good news doesn't play well with the demonisation of children or the rallying cry of 'broken Britain'.
