Folding laundry. Tub scrubbing. Vacation planning.

Women still shoulder the burden of many household chores and take on much of a family's emotional labour, according to recent studies.

Meanwhile, the U.S. Bureau of Labor Statistics consistently finds that working women take on 65 per cent of childcare duties — while working men take on the remaining 35 per cent.

Why? It's what's "expected" of women, researchers argue. It will take 75 years before women achieve gender equality in the household, according to MenCare, a global fatherhood campaign dedicated toward childcare parity.

But even when same-sex couples become parents, the division of labour isn't equally split, with one partner taking on more professionally and the other domestically.
