A birth is defined as the event in which a baby comes out of the uterus after a pregnancy of least 20 weeks gestational age or weighing 400 grams or more.
Gestational age is a clinical measure of the duration of the pregnancy. For the National Perinatal Data Collection gestational age is reported as completed weeks.
An instrumental birth is a procedure that uses instruments (forceps or vacuum extraction) to assist the baby to come out through the vagina.
Patient elected accommodation status is available for all jurisdictions from 2006.
