Northern Ireland
In Northern Ireland, the Births and Deaths Registration (Northern Ireland) Order 1976, as amended contains the definition:"still-birth" means the complete expulsion or extraction from its mother after the twenty-fourth week of pregnancy of a child which did not at any time after being completely expelled or extracted breathe or show any other evidence of life.Registration of stillbirths can be made by a relative or certain other persons involved with the stillbirth but it is not compulsory to do so. Registration takes place with the District Registrar for the Registration District where the still-birth occurred or for the District in which the mother is resident. A stillbirth certificate will be issued to the registrant with further copies only available to those obtaining official consent for their issue. Registration may be made within three months of the still-birth. United States
In the United States, there is no standard definition of the term stillbirth.In the U.S., the Born-Alive Infants Protection Act of 2002 specifies that any breathing, heartbeat, pulsating umbilical cord or confirmed voluntary muscle movement indicate live birth rather than stillbirth.The Centers for Disease Control and Prevention collects statistical information on "live births, fetal deaths, and induced termination of pregnancy" from 57 reporting areas in the United States. Each reporting area has different guidelines and definitions for what is being reported; many do not use the term "stillbirth" at all. The federal guidelines suggest (at page 1) that fetal death and stillbirth can be interchangeable terms.

A stillbirth can result in the feeling of guilt or grief in the mother. The term is in contrast to miscarriage, which is an early pregnancy loss, and Sudden Infant Death Syndrome, where the baby dies a short time after being born alive.Often the cause is unknown. Causes may include pregnancy complications such as pre-eclampsia and birth complications, problems with the placenta or umbilical cord, birth defects, infections such as malaria and syphilis, and poor health in the mother. : Causes tab,  Risk factors include a mothers age over 35, smoking, drug use, use of assisted reproductive technology, and first pregnancy. Stillbirth may be suspected when no fetal movement is felt. Confirmation is by ultrasound.Worldwide prevention of most stillbirths is possible with improved health systems. : Overview tab,  Around half of stillbirths occur during childbirth, with this being more common in the developing than developed world. : Info panel,  Otherwise, depending on how far along the pregnancy is, medications may be used to start labor or a type of surgery known as dilation and evacuation may be carried out.
