Induction of first births rose from one in three to nearly one in two. Their cesarean rate went up, not down.
United States hospital deliveries, 2016 to 2024, counted directly from the national birth-certificate files. Tap or hover on a year, or switch a line on or off.

Use the arrow keys on the chart to move between years.
First births at term are Robson groups 1 and 2: first birth, one baby, head down, 37 weeks or more. Induction is group 2a as a share of groups 1 and 2. These are observed rates in a population, not the effect of induction on any one woman. Source: National Center for Health Statistics natality public use files, 32.3 million deliveries. Explore every group in US Birth Data.

About
I am Professor of Obstetrics and Gynecology and Maternal-Fetal Medicine at the Zucker School of Medicine at Hofstra/Northwell, and Senior Ethics Consultant at Northwell Health.
My research uses US natality data to study how women give birth: induction, cesarean delivery and population outcomes. With Frank Chervenak I work on preventive ethics and the professional responsibility of physicians, including what informed consent should actually mean.
