Differential Voter Turnout in Compulsory versus Voluntary Voting Systems
Quick fact
Compulsory voting can raise turnout by 10 to 15 percentage points, and it disproportionately brings in less-educated and poorer citizens who often stay home in voluntary systems.
Why this is interesting
In countries where voting is voluntary, turnout often falls below 60%, but where it is mandatory, it jumps above 90%. Why does that difference matter for who ends up in power?
