The latest well-being report, The Good Childhood Report 2012 from The Children's Society reveals that half a million children across the UK are unhappy with their lives.
It outlines six key priorities needed for a happy childhood, after interviewing more than 30,000 children aged eight to 16.
Children who have low levels of happiness are much less likely to enjoy being at home with their family, feel safe when with their friends, like the way they look and feel positive about their future. Children unhappy in this way are also more likely to be victimised, have eating disorders or be depressed.
