Compulsory voting
Compulsory voting is an effect of laws which require eligible citizens to register and vote in elections, and may impose penalties on those who fail to do so. , 22 countries provide for compulsory voting, and 11 democracies — about 5% of all United Nations members — enforce it.
Voter apathy
Voter registration in the United States is an independent responsibility, so citizens choose whether they want to register or not. This led to only 64% of the voting age population being registered to vote in 2016. The United States is one of the sole countries that requires its citizens to register separately from voting. The lack of automatic registration contributes to the issue that there are over a third of eligible citizen in the United States that are not registered to vote.
