The Birth Registration Statement contains the details prescribed by Regulation, including, but not limited to: details of the baby such as sex, birth weight and whether a multiple birth; date and place of birth; and details of the parents and previous children. The parents of a child are jointly responsible for having the child's birth registered. A parent of a child born in WA and the Chief Executive Officer of a hospital, or any person responsible for the professional care of a mother at the birth, are each required to supply to the Registrar details relating to the birth of the child. Registration details are entered electronically by Births, Deaths and Marriages staff.

The Register includes all children born and subsequently registered in Western Australia. Stillbirths (deaths in utero that occur after 20 weeks gestation or at greater than 400 grams) are recorded in the Births Register. In addition to the administrative Birth Registration information additional information is collected for stillbirths on the Medical Certificate of Cause of Perinatal Death. Where there is sign of life at birth, but the neonate subsequently dies, the birth is recorded in the Births Register and the death is recorded in the Deaths Register. Although stillbirths are registered as a birth, for reporting purposes these are accounted for in perinatal death statistics.
