Compulsory voting
, 22 countries were recorded as having compulsory voting. Of these, only 10 countries (additionally one Swiss canton and one Indian state) enforce it. Of the 30 member states of the Organisation for Economic Co-operation and Development, 10 had forms of compulsory voting.
Right of foreigners to vote
The 1992 Maastricht Treaty imposed reciprocity inside the European Union concerning voting rights in local elections; this already existed for the European elections. In several European states, the public debate on the right of foreigners to vote was therefore renewed, as some foreign residents had the right to vote (European foreign residents) while others, non-Europeans, did not. As a result of this debate, Luxembourg, Lithuania, Slovenia and Belgium extended the right to vote, in different manners, to all foreign residents (which was already the case in Sweden, Denmark, Finland and Netherlands).
