Across 16 OECD countries, women spend on average 18% more time on secondary activities than men (25.6 hours per week, compared to 21 hours for men). Childcare in particular is often undertaken simultaneously with other tasks, so it might not be recorded among primary activities. The activities women engage in simultaneously are also different from those of men. As a result, men tend to associate more positive feelings with multitasking than women do (Offer and Schneider, 2011).
