Sánchez's cabinet is unusual in Spain and around the world. Though women make up about half the world's population, they hold 23 percent of the seats in national parliaments, up from 11 percent in 1995. In nearly 40 percent of countries, women make up less than 10 percent of elected parliaments, according to a 2017 United Nations study. In four countries, there are no women in national office. There are fewer than 30 female heads of state and heads of government. And women don't fare any better when it comes to cabinet positions. In 2017, 18 percent of all cabinet ministers were women.
