●Inquiry recommendation, K.1
The Inquiry recommends that the UK government and the Welsh Government improve data collected by children's social care and criminal justice agencies concerning child sexual abuse and child sexual exploitation by the introduction of one single core data set covering both England and Wales. In order to facilitate this, these agencies should produce consistent and compatible data about child sexual abuse and child sexual exploitation which includes: the characteristics of victims and alleged perpetrators of child sexual abuse, including age, sex and ethnicity; factors that make victims more vulnerable to child sexual abuse or exploitation; and the settings and contexts in which child sexual abuse and child sexual exploitation occur. Data concerning child sexual abuse and child sexual exploitation should be compiled and published on a regular basis. This should be capable of being collated nationally as well as at regional or local levels.

●UK Government
We accept that robust data collection on the scale and nature of child sexual abuse is critical to underpin and drive a more effective response to child sexual abuse. We have made a number of improvements in data collection and will additionally be driving further improvements to police performance data.

Each entry above links to a primary source — gov.uk written statement, consultation response document, or inspection report. The Index does not characterise government intent; it tracks what has been published.
How this page is built
Source and Response are verbatim from primary documents. The Evidence trail records published activity since — written statements, consultation outcomes, inspection findings, parliamentary references. The Index does not paraphrase or characterise intent; it tracks what has been published. Where the evidence is the absence of action (a missed deadline, a slipped timetable), that absence is documented from primary sources rather than inferred.
This recommendation's data is verified periodically against primary sources. The Index is monitored for staleness weekly.
