Children's lives are massively different depending on where they live, a new report has shown.
You are far more likely to be poor, have a bad diet and do badly at school if you live in certain areas.
Kids in some places are also more likely to be fat, homeless and experience bad traffic problems.
The study, by charity Save The Children, shows that a third of children still live in poverty, but it's much worse in some parts of the country.
Some key facts are:
- Wales has the highest rate of child poverty
- Children in Northern Ireland have the highest death rates
- Scottish children have the worst diets
- Children in Wales have the highest rate of teenage pregnancies
Save The Children say the report shows how there are more and more differences in the way children are living across the UK.
It called on the government to do more research and to look at ways of improving conditions for all children, no matter where they live.
