25percent of ten-year-olds are never allowed to play on their own
Now I'm not that old and times have changed so drastically since I made the street my personal playground.
The UK is trying to do something about it now.
Ministers are concerned that children now have fewer opportunities than ever to play outdoors thanks to over-zealous health and safety crackdowns and a "no ball games here" culture.
Mr Balls unveiled the figures today as he launched the consultation to create a blueprint to improve play areas.
Research has found that the average age at which children are allowed outside without adult supervision has risen from around seven years in the 1960s and 70s to just over eight years now.
One in three parents will not even allow older children, aged eight to 17, to play outside the house or garden.
No doubt, modern technology is partly to blame for this development as well.
