In Belgium _every_ citizen is automatically registered.

I feel you are comparing apples to oranges. If every citizen in the US was registered, then how do the numbers compare then?

The other registration, ie. not the automatic one, in Belgium applies to foreigner who live in Belgium and want to have some say in local elections. I can't even see how this kind of registration even compares to the voter registration in the US. Well, they both have the word "registration" but it isn't even remotely the same.

If you need help interpreting the numbers of registration vs voting, let me know. I can search the real numbers and break them down to citizen (auto-registration) and non-citizens (who could register but didn't) and non-voters (both categories combined but didn't show up at the election)
