While midwives are authorized to provide abortion care in 24 states and DC, their role in abortion provision remains largely invisible or underrepresented in national surveillance efforts. Abortion care provided by midwives, who were among the first abortion providers in this country, has been firmly established as safe, effective, and acceptable. To ensure accurate surveillance of both the abortion workforce and abortion incidence, it is essential to identify how many midwives are providing abortion care and quantify their contributions. We will embed new abortion-focused questions into a national survey of midwives, using the American Midwifery Certification Board roster to recruit a representative sample of 1,000 midwives practicing in the 24 states and DC where abortion provision is within their scope of practice. The study will answer three research questions: (1) How many midwives provide abortion care, and what are their individual, practice, and state characteristics? (2) How many abortions did they provide in 2025, by type, gestational duration, and provider volume? (3) What barriers and enablers to providing abortion care do midwives identify from their experiences? This study will provide essential data on the composition of midwives engaged in abortion care and the volume of care provided. The findings will fill critical gaps, informing educational initiatives, workforce planning, policy advocacy, and efforts to improve reproductive health equity.
