How is the Danish system actually considered a "draft", when only 100 people are actually drafted and the rest is there voluntarily ? Out of 30.000 Danish men who reach the draftable age every year ?
There are two intakes a year, the other one is a bit bigger (2900 people in 2011), so around 200 people are actually drafted, but, as you say, still not a lot considering that there are 30.000-35.000 Danish men draftable every year.
Historically way fewer volunteered, in the 70's it was about fifty percent and as late as 2006, the rate of volunteers was "only" 76 %. So it's only in the last five years that the rate of volunteers have been 87 % or higher, and you could question how much of a draft it really is now. Apart from the financial crisis, other reasons for the high rate of volunteers are a reduction of the number of people needed (from 5660 in 2006 to 5067 in 2011) and a higher rate of women (3 % in 2006, 10 % in 2011). Women are not a part of the draft, so when a woman enters the military service, she fills a spot that would otherwise have been filled by a drafted man.
The centre-left government would like to suspend the draft and only take in volunteers, you can't abolish it without changing the constitution which is very difficult in Denmark, but the current agreement on defence includes three opposition parties (Liberals, Conservative People's Party, and Danish People's Party) who are not very keen to do that. The agreement runs until 2014, and it's considered very bad taste to brake these agreements, so changes probably will not happen until at the earliest 2014, but currently the government's supporting party The Red-Green Alliance are opposed to the plans as well so a suspension seems unlikely. Despite wanting to suspend the draft, the government will like to keep the day where mental, and health tests are made, and the different kinds of military service presented. It's at this day that you, as it is now, inform whether you want to join voluntarily or want to be included in the draft. Furthermore, the government would like to make it obligatory for women to attend this day as well; a proposal which is backed by the opposition parties.
