Fig. 3: Turning/Satiation of stress with household income.
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) gender (Male (NMale = 1,044,259, Female (NFemale = 993,908)), (b) race (White (NWhite = 1,602,799), Black (NBlack = 162,877), Hispanic (NHispanic =157,446)), and (c) political affiliation (Republican (NRepublican = 496,289), Democrat (NDemocrat = 544,552), Independent (NIndependent = 552,089)) 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 income relationship.
