Our research reveals persistent geographic variation in C- section rates for both low- and high-risk groups. Counties with elevated C-section rates consistently perform more C-sections across mothers at all levels of appropriateness for the procedure. These elevated rates of C-section in high C-section counties are associated with reduced maternal and infant morbidity. We also find that C-section decisions are less responsive to underlying risks for Black mothers relative to white mothers, suggesting potential welfare-reducing disparities UR - https://www.nber.org/papers/w31871 UR - http://dx.doi.org/10.3386/w31871 ER -
