Fig. 4: Turning/Satiation of stress with household income with lifestyle factors.
From: Higher income is associated with greater life satisfaction, and more stress
Trends of stress, as the predicted probability of experiencing prior-day stress, against household income ($, logarithmic scale) by (a) health (Healthy (NHealthy = 685,182), Unhealthy (NUnhealthy = 1,328,988)), b smoking (Non-Smoking (NNon-Smoking = 1,690,769), Smoking (NSmoking = 346,513)), c being social (Non-Social (NNon-Social = 247,562), Social (NSocial = 330,108)), d basic needs met (Needs-Unmet (NNeeds-Unmet = 419,809, Needs-met (NNeeds-met = 1,524,920)), e view of the economy (Moderate Economy (NModerate = 1,120,182), Positive Economy (NPositive = 271,539)), and (f ) working hours sub-groups (0–15 h (N0-15 h = 43,979), 15–30 h (N15-30 h = 78,342), >30 h (N>30 h = 660,139), Unemployed (NUnemployed = 63,013)) for the years 2008–2017. The curve is a fitted cubic spline showing the 95% confidence interval. Satiation (turning point) is indicated by an empty (a full) circle, derived from the non-negative region of the slope of the stress versus household income ($, logarithmic) relationship.
