Electoral Systems and Women's Legislative Representation

Quick fact

Globally, countries using proportional representation (PR) elect about 25% women to their national parliaments, while majoritarian systems average below 15%—a gap that persists even after controlling for economic development and culture.

Why this is interesting

Imagine two countries with similar cultures and histories—yet one elects twice as many women to parliament. Why? The answer lies in how votes are translated into seats.
