The findings of the 1993 and 1994 American College of Nurse-Midwives Membership Surveys are presented and compared with a 1991 survey. The approximately 3,600 respondents had a mean age of 43 years, and most members were female and Caucasian. Two-thirds of the certified nurse-midwives (CNMs) who responded had earned master's degrees. Approximately one-half of the respondents were employed by physicians or hospitals, and 71% reported that their primary employment involved clinical care with attendance at births. More than 90% of CNM respondents who reported site of birth attended births in hospitals. There has been a demonstrated increase in racial/ethnic diversity of the membership since the 1991 survey.
