Overview
- Summary of dataset and variables
Number of maternity birth records and births broken down by local health board and maternity unit.
These statistics are derived from two data sources: the Maternity Indicators dataset (MI ds) and the National Community Child Health Database (NCCHD). Both data sources are provided to the Welsh Government by Digital Health and Care Wales (DHCW).
The MI ds combines records from a mother’s initial assessment with a child’s birth record.
The NCCHD was established in 2004 and consists of anonymised records for all children born, resident or treated in Wales and born after 1987. The database brings together data from local Community Child Health System databases which are held by local health boards (LHBs) and its main function is to provide an online record of a child’s health and care from birth to leaving school age. The statistics used in this release are based on the data recorded at birth and shortly after birth.
Full details of every data item available in the Maternity Indicators dataset are available through the NHS Wales Data Dictionary.
- Data collection or calculation
Data from the Maternity Indicators dataset only includes initial assessment data where the initial assessment and birth both occurred in the same health board, in Wales only.
Births to Welsh resident mothers who gave birth in England or in any other country outside of Wales are not included in the data.
Data for each calendar year refers to when the baby was born. Initial assessments may have taken place in the previous year but would be counted in the year in which the birth occurred.
The NCCHD includes records of all children born in, resident in or receiving services in their relevant local health boards. This means the database contains some information for some children not currently residing in Wales; however, unless otherwise stated, all statistics produced from data sourced from this database is filtered to only include those children born in Wales. It also means that data is available for Welsh resident mothers who gave birth in England.
Data reference periods: 2016 to 2024 (MIDs) 2011 to 2024 (NCCHD)
- Statistical quality
From 1st April 2019 health service provision for residents of Bridgend local authority moved from Abertawe Bro Morgannwg to Cwm Taf. The health board names changed to Cwm Taf Morgannwg University Health Board and Swansea Bay University Health Board. Data for Abertawe Bro Morgannwg and Cwm Taf are available for previous years in this table.
For the 2019 data in this table, the Wales total is not the complete 2019 Wales total as it only contains data from Abertawe Bro Morgannwg local health board and Cwm Taf University local health board.
More detailed information on the sources of data and analyses in this statistical release are provided in the quality report.
