This paper examines children's time with fathers in intact families using data from the Panel Study of Income Dynamics. It finds that while mothers still bear the majority of parenting responsibilities, fathers' involvement has increased relative to mothers. A "new father" role is emerging, particularly on weekends. Fathers' involvement varies by weekday and weekend, with wages and work hours negatively affecting weekday involvement but not weekends. Mothers' work hours have no effect on children's time with fathers. On weekends, Black fathers are less involved, while Latino fathers are more involved than White fathers. The weekday-weekend difference suggests that gender inequality alone cannot explain household labor division. The role of fathers has evolved from being primarily economic providers to also providing daily care. Research shows that while paternal involvement has increased, fathers still spend less time with children than mothers. Recent studies highlight the long-term benefits of paternal involvement on children's achievement and behavior. However, many children have little contact with biological fathers. Estimates of paternal involvement vary widely due to differences in samples, child ages, and methodologies. This study uses a nationally representative sample of 1,761 children aged 0–12, with data collected through time diaries. It examines children's time with fathers on weekdays and weekends, and how child and parent characteristics affect this time. The study finds that children spend about 1 hour and 13 minutes with fathers on weekdays and 2 hours and 29 minutes on weekends. Fathers' involvement varies by child age, gender, and parent characteristics. For example, better-educated fathers are more involved, while higher earnings have a negative effect on involvement. On weekends, Black fathers are less involved, while Latino fathers are more involved than White fathers. The study also finds that fathers' involvement relative to mothers' varies by activity type. On weekdays, fathers spend about 60–82% of the time mothers do with children. On weekends, this ratio increases to 80–94%. Fathers' involvement in personal care activities is 62% of mothers' level, while in play and companionship activities, it is 88%. The study concludes that while fathers' involvement has increased, they still have a lower relative contribution in areas like household activities, infant care, and studying. The findings suggest that fathers' involvement is influenced by socioeconomic factors, and that further research is needed to understand the dynamics of household labor division.This paper examines children's time with fathers in intact families using data from the Panel Study of Income Dynamics.
