The 44% drop in maternal deaths

Pioneer of antiseptic obstetrics - Deceased (1865)

In 1990, approximately 532,000 women died each year from pregnancy and childbirth complications. By 2015, that number had fallen to 303,000—a 44% reduction in the maternal mortality ratio, from 385 to 216 deaths per 100,000 live births. The decline represents one of the largest coordinated public health efforts in history, driven by expanded access to skilled birth attendants, emergency obstetric care, and basic medical interventions like antibiotics and blood transfusions.

In 1900, one in seven babies born in the United States or United Kingdom died before their first birthday. By 2017, the rate had fallen to roughly 4-6 per 1,000—a decline exceeding 95%. This transformation ranks among the most consequential achievements in human history, fundamentally altering how families experience childbirth and early childhood.
