A new study of children's lives in Great Britain has revealed how happy kids are.
The report by the Office of National Statistics said that three quarters of children aged 10 to 15 said their happiness levels were moderate or high.
It wasn't all good news though 1 in 8 said they suffered from bullying.
Nearly one in eight boys were happy with their appearance but only 68% of girls were happy with their looks.
The research also found that 61% of children with problem feel happy to talk to their mum about it compared to only 51% kids did ten years ago.
