Note: : The figure presents predicted means of net affect — defined as experienced happiness minus the average of negative emotions (stress, pain, sadness, and tiredness) — when doing childcare for mothers and fathers across five child age groups (0–2, 3–5, 6–8, 9–11, and 12+). Data come from the ATUS Well-Being Modules administered in 2010, 2012, 2013, and 2021. In these modules, respondents report how they felt while performing three randomly selected activities lasting at least three minutes, with feelings measured on a six-point Likert scale (0 = not at all, 6 = very much). Predicted means are estimated separately by gender, controlling for age, educational attainment, marital status, diary weekday, and year fixed effects to absorb wave-specific reporting differences. Estimates are weighted using ATUS survey weights. Vertical bars represent 95% confidence intervals. The estimates capture conditional associations rather than causal effects, and should be interpreted as descriptive evidence.
