Selective Scrutiny and Statistical Drift: How CMS Evidence Is Shaping Policy Without Full Context
Child Maintenance Service debate on 17 March 2026 in Westminster Hall, This clip shows the exact moment the statistic is introduced during the debate.
For completeness, the official transcript is available via Hansard:

The Hansard record confirms the wording used, including the description of the statistic as “national evidence”.

There is a growing issue at the centre of the Child Maintenance Service (CMS) debate.
It is not just about policy failure.
It is about who gets heard, how evidence is presented, and how that evidence evolves as it moves through the system.
Who Gets Heard — And Who Does Not
On its own website, Gingerbread confirms that it has participated in roundtable discussions with Ministers, including Baroness Sherlock, providing direct input into CMS policy discussions.
At the same time, groups such as STOPSuicides UK (STOPS), which are raising evidence of:
- Suicide linked to CMS processes
- Elevated mortality among paying parents
- Safeguarding failures
have been repeatedly refused equivalent engagement.
This is not about whether Gingerbread should be heard.
It is about why others are not.
The Origin of the “77%” Statistic
A key statistic now widely cited in CMS debate originates from Gingerbread’s 2024 research.
The report is based on:
- A survey of 1,622 respondents
- A self-selecting sample
- Limited to parents with care
As the report states:
“Our survey of 1,622 separated parents…”
Within that group:
77% of parents with care using the CMS reported experiencing domestic abuse from the other parent.
This is a specific finding about a defined group.
The First Shift: Public Framing
On its website, Gingerbread presents this statistic more broadly, referring to:
“parents using the CMS”
At this stage, key context is no longer visible:
- The sample size
- The survey nature of the data
- The limitation to parents with care
The effect is subtle but significant:
A targeted survey finding begins to read as a general system-wide observation.
The Second Shift: Parliament
In the Westminster Hall debate on 17 March 2026, the statistic was presented as:
“The national evidence is deeply concerning. Research by Gingerbread… found that 77% of primary carers using the CMS reported experiencing domestic abuse…”
At this point, the statistic is no longer:
- A survey result
- A subset finding
It has become:
“national evidence”
The Third Shift: Media Reporting
This framing did not stop in Parliament.
A subsequent report in The Bolton News (20 March 2026) repeated the statistic:
“77 per cent of primary carers using the CMS reported experiencing domestic abuse…”
No reference is made to:
- The sample size (1,622)
- The survey methodology
- The limited population
The statistic is now presented as part of a general narrative about the CMS.
The Evidence Chain
The progression is clear:
- Survey (Gingerbread Report, 2024)
– 1,622 respondents (parents with care) - Public Narrative (Gingerbread Website)
– Broader framing - Parliament (Hansard, March 2026)
– Presented as “national evidence” - Media (March 2026 reporting)
– Repeated without context
At each stage, the original limitations become less visible.
Why This Matters
This is not about whether the statistic is valid.
It is.
The issue is how it is being used.
When presented without context, it creates the impression that:
The majority of CMS cases involve domestic abuse
That conclusion cannot be drawn from the underlying data.
The Missing Side of the System
At the same time, there is far less attention given to evidence showing harm elsewhere in the system, including:
- Parliamentary evidence of suicide linked to incorrect CMS assessments
- Freedom of Information data identifying deaths within the system
- Analysis indicating elevated mortality among paying parents
- Evidence of distress and systemic administrative failure
This creates an imbalance:
One form of harm is amplified — another is underrepresented.
Should This Be Clarified?
Members of Parliament are responsible for statements made in Parliament.
However, where research produced by external organisations is relied upon in public debate, those organisations are not entirely detached from how their work is understood.
While Gingerbread is not responsible for how its research is framed by others, it is aware that its findings are being used in:
- Parliamentary debate
- Media reporting
- Policy discussions
That gives rise to a reasonable expectation:
Where research is presented beyond its methodological scope, clarification becomes necessary to avoid misunderstanding.
Policy Without Full Context
This matters because these narratives are shaping:
- Public understanding
- Legislative proposals
- Enforcement policy
At the same time, enforcement powers are expanding, including reduced reliance on judicial oversight.
If policy is based on incomplete or overstated evidence, the risk is clear:
Problems are not solved — they are shifted.
Final Point
This is not about dismissing the experiences reflected in the survey.
They matter.
But so does how they are represented.
A survey of 1,622 respondents has moved from a specific finding to “national evidence” in Parliament, and is now being repeated in the media without context.
That is not a minor change.
It is a material shift in meaning.
And where such shifts influence policy, the need for clarity is not optional.
