This paper examines the long-term and multi-generational benefits of skilled birth attendance (SBA), which involves having a trained midwife or doctor present at delivery to safely perform normal deliveries using aseptic techniques and provide first-line emergency obstetric care. Using data on the county-by-county rollout of SBA in China from the 1930s to the 1970s, our research first demonstrates that the SBA reform substantially reduced neonatal mortality. We then show that exposure to skilled delivery during birth leads to a 1.5% increase in adult income. Moreover, we discovered that the benefits of exposure to SBA in previous generations extend to subsequent offspring. Children with at least one parent who experienced SBA have a 2.6% higher monthly income in adulthood than those whose parents did not have access to SBA. We also present evidence of several underlying mechanisms, including improved physical and mental health, better educational outcomes, and enhanced cognitive abilities. Our findings indicate that having skilled health professionals attend childbirths can result in significant long-term and multi-generational benefits.
