At what age can children be left home alone?

I've come across videos online about differences between parenting in the USA and for example in the Nordic countries and now I'm a little curious, hence the question.

To my understanding, children in the Nordic countries are left home alone in a younger age more easily than their peers in the States. I guess I've also heard that there are laws and legal ages there on this matter but I may be wrong.

So, at what age do you think children can be left home alone for a couple of hours, tops, during the day? Are there laws on this matter?
