How Many Sans Papiers Are There in Switzerland

I have written a blog post for the NCCR on the move on how many sans-papiers there are in Switzerland (in German). The blog post draws on a study I was involved in two years ago, where we estimated the number of sans-papiers in Switzerland. The main message: of course we don’t know how many there are, so our best estimate also comes with uncertainty. Strangely enough, when this study is cited in politics, I can always see a single precise figure — a figure we always greatly de-emphasized in the report.
