Since the 20th century, the number of women who give birth from home has significantly declined. Although there are some parts in the U.S. that legally consider midwife-assisted delivery to have some benefits over the health condition of pregnant women during the child delivery, some states in the U.S. including Alabama, Georgia, Illinois, Indiana, Iowa, Kentucky, Maryland, North Carolina, South Dakota, and Wyoming do not legally allow the practice of midwife-assisted delivery not unless the midwife has been certified as Nurse Midwife (Mana).
