The Office for National Statistics (ONS) Annual District Birth Extract (ADBE) is a register of all births relating to Welsh residents, including those born out of Wales and subsequently registered in Wales. Birth statistics are derived from information recorded when live births and stillbirths are registered as part of civil registration, a legal requirement; these data represent the most complete data source available. The registration of births is a service carried out by the Local Registration Service in partnership with the General Register Office (GRO) in England and Wales. ONS produces five birth statistical releases between July and November each year. These releases include statistics about births that occurred during the previous year. This is all data related to the ONS Annual District Birth Extract.
