- 25% of new fathers experienced symptoms of depression in the first year after birth (meta-analytic estimate)
- 26% of couples reported increased conflict after the transition to parenthood (study estimate)
- 2.1x higher odds of marital disruption were found for couples who experienced major stressful events in the first 5 years after marriage (context includes early parenthood timing in cohort analyses)
- First childbirth increases the risk of marital dissolution; in one U.S. cohort, the hazard of divorce increased after the birth compared with pre-birth periods
- 45% of mothers say it is hard to combine paid work and family responsibilities (OECD survey evidence)
- 60% of parents report that lack of sleep after childbirth affects their mood and stress (study estimate)
- 2.5x more likely sleep problems are reported in the first 3 months postpartum compared with pre-pregnancy for many women (review estimate)
- The median age at first marriage in the U.S. was 29.8 for men and 28.0 for women in 2023 (context for timing of parenthood and divorce risk)
- 1 in 5 children experience parental separation or divorce in the early years in the U.S. (estimate from national research synthesis)
- A meta-analysis found that parental divorce is associated with elevated risk of behavioral and emotional problems in children compared with non-divorced families (effect size reported)
- About 3.6 million births occurred in the United States in 2023 (CDC/NCHS)
- In the U.S., 50.9% of births were to unmarried women in 2022 (CDC/NCHS)
