Nearly half the world's population had elections this year, but for the first time in at least 20 years, progress for women's representation has slowed. In 60% of countries that voted this year, the number of women in parliament fell.

Stephanie Hegarty, the BBC’s population correspondent, discusses some of the countries where fewer women were elected and explains some of the factors behind the drop. She also looks at the regions — from Latin America to Africa — where female politicians made gains.

We also hear from Puakena Boreham, a former member of parliament in the Pacific island of Tuvalu, and Indira Kempis, a former member of the Senate in Mexico. They discuss the importance of female representation and the challenges that female politicians face.
