File formats and conventions
Symbology
The following symbols are used in the underlying data files as follows:
c to protect confidentiality - secondary suppression may also be applied to figures to protect confidentiality
x data not available
Where any number is shown as zero, the original figure submitted was zero.
Rounding
In the file ‘Sub-national notifications with contextual data’:
numbers of notifications at a regional level have been rounded to the nearest 10. Therefore, regional numbers may not sum to national totals.
national and regional children in need figures have been rounded to the nearest 10. Therefore, local authority numbers may not sum to regional totals and regional numbers may not sum to national totals.
All other figures are unrounded.

Footnotes
Most notifications in the other category relate to incidents with child perpetrators who were themselves known or suspected to have been abused or neglected.
For 2019, there is likely to be an undercount in the number of notifications recorded with a disability status of not known (with a corresponding overcount in the number of notifications recorded as involving children with no disability).
For 2019, there is likely to be an overcount in the number of notifications recorded as relating to children on a protection plan.
Children known to GP services have been excluded (where this information was recorded) from 2023 onwards but were included prior to 2023.

Footnotes
The source of the data on serious incident notifications is the Child Safeguarding Incident Notification System (opens in a new tab). The statistics show the number of incidents notified in the period, rather than the number of incidents that occurred in the period and are based on one notification per incident, which can relate to more than one child in some instances. The local authority should notify the Child Safeguarding Practice review panel within 5 working days of becoming aware that the incident has occurred. However, in some cases, there can be delays in notifications being submitted. When interpreting data on serious incident notifications, local authority contextual information is an important consideration. Local authorities with larger populations tend to be more likely to report more serious incident notifications than those with smaller populations. Those with higher levels of deprivation also tend to be more likely to report higher rates of serious incident notifications than those with lower levels of deprivation. In addition, whilst data quality has improved in recent years, DfE is aware that, in some instances, not all incidents that meet the definition for a serious incident are notified. For these reasons, neither high nor low numbers of serious incident notifications alone should be interpreted as a performance measure of the local authority or its workforce.
The children in need at 31 March figures, based on the Children in Need statistics release, provide further contextual information to the data on serious incident notifications. As 2025 data were not available at the time of publication, the serious incident notification figures for 2025 show the latest (at the time) 2024 figures alongside.
Mid-year ONS population estimates (opens in a new tab), based on children aged 0 to 17 years in England, provide further contextual information to the data on serious incident notifications. As 2024 estimates were not available at the time of publication, the serious incident notification figures for 2025 show the latest (at the time) 2023 estimates alongside.
On 1 April 2021, the unitary authorities North Northamptonshire and West Northamptonshire were formed, replacing Northamptonshire County Council. However, data is provided under the former Northamptonshire basis in 2022 and 2023, in addition to being provided for earlier years, but is provided under the new North Northamptonshire and West Northamptonshire basis from 2024.
