It is not 10. As Judy and Sunnydays said there is no age. The theory behind this is simply that if you were to say a 10 year old could stay home alone, not all 10 year olds are equally as responsible. It's about maturity versus number. Some teenagers are not responsible and mature enough to be home alone so really the age they are is not the important factor.
