I am surprised that 13% said God was not involved at all. The numbers I have seen for atheist/agnostic show them to be only about 3-4% of the population. Alot of those "no religious preference people" must be atheist but don't want the label.
I don't think the question of 'religious preference' necessarily relates to the issue of atheist vs agnostic. Some belief systems support a non-interference, dynamic, but not an institutional approach to doing so, and concomitantly, no worship requirement.
There are plenty of people who believe in God (like, for example, Einstein) who don't believe in a God who intervenes in the material world: deists. Those people aren't atheists.

Maybe those who think visiting aliens planted life on earth (or gave it one or more big nudges) make up some of the difference.
