Federal Elaction

Just a bit data:

There are 82.117.000 people who live in Germany (according to a census from July 2008).
About 62.000.000 are eligible to vote.
That means round 1/4 off all residents are not eligible to vote. There can't be that much children who are younger than 18... If I am not mistaken there are round 80tsd births per year; that means there should be round 1,4 mil. under 18-years olds.
Brings me to the question - who are the missing 18,5 million people?

Now waiting for the first results...
