Since women entered the workforce en masse, what they earn relative to their husbands has been a hot topic. Many decades later, most of the world’s women do not earn more than their men. A landmark report, which is the first to look at gender disparities in global household incomes, used data from 2.85 million heterosexual couples aged between 18yo and 65yo across 45 countries. It found a pay gap between husbands and wives across countries and social classes, including in Nordic countries that champion equality. There are many factors at play, including social norms and women leaving work to start a family. But researchers said the time taken up with unpaid care was “the main barrier preventing women from getting into, remaining and progressing in the labour force”.
