2.11 Types of voting systems

Electoral systems can be divided into three essential subgroups:

1. majoritarian voting systems (use majoritarian formulas) - e.g. plurality method, Borda count, Instant Runoff (alternative vote),

2. proportional representation voting systems (use proportional formulas) - apportionment methods such as Hare-Hamilton, D’Hondt and Sainte-Lague,

3. mixed voting systems (combine two or more different types of electoral formulas, for example majoritarian and proportional); e.g. German mixed-member proportional system.
