The International Parliamentary Union (IPU) maintains up-to-date statistics, as submitted by national parliaments, on the participation rates of women in national parliaments around the world. It provides world and regional averages, broken down by total number of Members of Parliament for Upper and Lower Houses, further broken down by gender.
