The BВC is doing its biggest ever internet survey about young people in Britain today to find out about their lives and their worries. They want to help parents and teenagers to talk and understand each other better. Thousands of people are logging on to take part — so far more than 30,000 teenagers and 12,000 parents.

What’s best thing about being a teenager?
Most teenagers say, ‘Going out and having more freedom’. ‘Cool music and fashion’ and
‘the internet’ are also popular answers.

__________________________________________________________?
Young people most like the love and support they get from their parents ... and their sense
of humour, too. But 40% say that they like their parents because they give them money!

__________________________________________________________?
Many young people complain about how the media shows teenagers and many parents
agree: ‘All teenagers have bad publicity ... and they are not all bad!’ said one parent. Young
people also complain about exam pressures, changing moods and boyfriend/girlfriend relationships.

___________________________________________________________?
About 20% of teenagers want their parents
to give them more freedom. ‘Often parents treat you like a child and don't respect your opinions,’ writes one. ‘Why can’t I go to places where my friends go, like nightclubs?’says another. And 29% of young people really hate their parents’ clothes! On the other hand, 3% parents want their teenage children to listen to them more and to help more in the house.

___________________________________________________________?
One parent said, ‘If our kids have a serious problem, they can always talk to us about it.’ But teenagers don’t always agree. Most feel that they can talk to their parents about everyday things but 60% say they can’t talk to their parents about serious personal problems with relationships, drugs and alcohol. They find it easier to talk to friends about these things.

___________________________________________________________?
The two big worries for young people are exams and their appearance. In fact, 48% say
that their appearance is their biggest worry.Parents worry most about their children’s
schoolwork.
