Note. Married was coded as 0 = cohabiting, 1 = married. Age was coded in years. Education was measured as a dichotomous variable, where 1 = college degree or more education and 0 = less than a college degree. Race was measured as a dichotomous variable where 1 = Non-Hispanic White and 0 = Other. Weekly work hours was measured from the time-diary data as minutes of work (including working, checking work email, commuting, and other income generating activities). Following (Yavorsky et al., 2015), we calculated the sum of the minutes of work on the workday times 5 and the minutes of work on the nonworkday times 2, and then divided the sum by 60 to get a weekly estimate of work hours. Family n is the number of families in the sample at that wave. n is the number of individuals who reported data at that wave.
