The United States is one of the few democracies in the world where the government does not take any responsibility in registering its citizens. This one-of-a-kind, self-initiated voter registration process acts as a major barrier to voter turnout and leads to often- inaccurate voter rolls. In contrast, the international norm is a process of government-mandated automatic voter registration of every citizen who reaches voting age. This report explores how other major well-established democracies (Canada, Australia, Sweden, Italy, New Zealand and others) concretely manage to build comprehensive, inclusive, accurate voting rolls that leave no voters behind while ensuring a high level of privacy.
