Women fared best in Rwanda, Norway and Sweden, but there are no women MPs in nine countries, including Saudi Arabia and Kyrgyzstan.
On average, women made up about 20% of the deputies elected in the 39 countries which held parliamentary elections last year, the IPU report said.
The numbers fall short of UN targets set in 1995 of a minimum of 30% women lawmakers in all parliaments.
Don’t forget, this year’s CSW is focusing on women and decision-making. For more information on women’s political representation, check out the Women’s Environment and Development Organization’s 50/50 campaign.
