"By most objective measures the lives of women in the United States have improved over the past 35 years, yet we show that measures of subjective well-being indicate that women's happiness has declined both absolutely and relative to male happiness. The paradox of women's declining relative well-being is found examining multiple countries, datasets, and measures of subjective well-being, and is pervasive across demographic groups. Relative declines in female happiness have eroded a gender gap in happiness in which women in the 1970s typically reported higher subjective well-being than did men. These declines have continued and a new gender gap is emerging—one with higher subjective well-being for men. Our findings raise provocative questions about the contribution of the women's movement to women's welfare and about the legitimacy of using subjective well-being to assess broad social changes."
