Overview

Summary of dataset and variables

Number of maternity initial assessment records, maternity birth records, live and still births by local health board.

This data is derived from the Maternity Indicators dataset, provided to the Welsh Government by Digital Health and Care Wales (DHCW).

The Maternity Indicators dataset combines records from a mother’s initial assessment with a child’s birth record.

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.

Includes the following number of deliveries that could not be linked to an initial assessment record: 717 in 2016, 747 in 2017, 719 in 2018, 1,522 in 2019, 969 in 2020, 903 in 2021, 598 in 2022, 654 in 2023, 659 in 2024 and 349 in 2025.
