Anderson is a common Swedish last name - in its origin meaning the son of Anders.

An other example could be Peterson (Swedish) and Petersen (Norwegian/Danish).
The last name 'Andersen' is Scandinavian. It can be of either Norwegian or Danish origin, but not Swedish as the parallel name in Swedish would be 'Andersson'. If we are talking about US citizens then there is approx. twice as big likelihood of Norwegian ancestry compared to Danish as there were 2,25 times as many Norwegian immigrating to the US.
