Comparative Analysis of Mixed-Member Proportional Representation

Quick fact

Germany is often credited as the pioneer of MMP; in its first MMP election in 1949, the system produced a parliament where the SPD and CDU/CSU each received about 29% of the vote and ended up with 29% and 31% of the seats respectively, achieving remarkable proportionality.

Why this is interesting

Ever wondered why some elections produce a parliament that reflects the exact vote share of each party, while others give one party all the power? Mixed-member proportional representation tries to do both—how does it pull that off?
