Statistics on Women's Smoking Status at Time of Delivery: England, Q4 2024/25
Official statistics
The SATOD data collection has now been retired
This is the last quarterly report that includes comparative data from the original Smoking at Time of Delivery (SATOD) data collection and the Maternity Services Dataset (MSDS). This dual reporting covering the 2022-2023 to 2024-25 period has helped to determine the retirement of the SATOD data collection due to the close alignment between the two sources. Subsequent reporting will include data from MSDS only.

Summary
This report presents statistics on women’s smoking status at time of delivery, at Sub Integrated Care Board (Sub-ICB), Integrated Care Board (ICB), regional and national levels. This release includes finalised data for quarter 4 of 2024-25 using data from the Smoking at Time of Delivery data collection which is submitted by commissioners (presented as SATOD v1). Alongside this, comparative data using the Maternity Services Dataset (MSDS) is also presented using data submitted by Trusts (presented as SATOD v2) as a time series from quarter 1 of 2022-23 to quarter 4 of 2024-25. This is available for the same geographical breakdowns and includes an additional breakdown for Local Authorities. SATOD has been dual reported for the last time in 2024-25.
The SATOD v1 data collection has now ceased from Q1 2025-26 and future SATOD reporting will be replaced with SATOD v2 data from MSDS. This decision has been based on how closely the estimates have aligned during dual reporting, a Health and Social Care Statistics consultation carried out in 2024 (link available in Related Links below) and being driven by the need to reduce burden on data collection and duplication across the NHS. MSDS data is submitted monthly by Trusts so sub-ICBs (or other commissioning entities) are no longer required to submit data for this collection from Q1 2025-26. Subsequent reporting will include data from MSDS only. A Methodological Change Notice will be published in due course.

Key Facts
Key facts are for annual or quarter 4, 2024-25.
For SATOD v1, 6.1% of pregnant women were known to be smokers at the time of delivery in 2024-25.
This is a decrease from 7.4% in 2023-24.
For SATOD v2, 5.6% of pregnant women were known to be smokers at the time of delivery in 2024-25.
This is a decrease from 7.2% in 2023-24.
For SATOD v1, 6.0% of pregnant women were known to be smokers at the time of delivery in quarter 4 of 2024-25.
This is a slight increase from 5.9% in the previous quarter (Q3, 2024-2025).
For SATOD v2, 5.1% of pregnant women were known to be smokers at the time of delivery in quarter 4 of 2024-25.
This is a slight decrease from 5.5% in the previous quarter (Q3, 2024-2025).
The 2024-25 estimates from SATOD v1 and SATOD v2 are closely aligned.
Estimates in the quarterly time series going back to Q1 2022-23 are also closely aligned, indicating that MSDS is a good replacement as the data source for this publication.
