There were only 12 countries in the world in 2016 having equal parliaments, according to figures from the Inter-parliamentary Union (IPU). The countries concerned are Spain, Namibia, Nicaragua, Finland, Ecuador, South Africa, Mexico, Senegal, Sweden, Iceland, Cuba, and Bolivia.
Only two countries have more women than men in their parliament, Bolivia with 53.1 percent women and Rwanda with 63.8 percent women. In fact, Rwanda has so many women in its parliament that it is purely numerically not equal.
We can learn from these countries that there is a need for proportional voting and constituencies with not only one candidate, but a list for each party where you can have as many women as men and both young and old and depending on how many votes the party gets the more candidates to get elected.
And one should study the quotation system in Rwanda and Sweden for example. In Sweden, it is the parties themselves who decide if there shall be curved lists. So now when we have a new conservative extreme rightwing party who mostly have men on their lists, we have a less gender even parliament. What about Senegal?
