SAFECHAIN™ EVIDENCE REPOSITORY™
Building the Evidence Base for Institutional Integrity, Safeguarding, and Systems Reform
About This Repository
The SAFECHAIN™ Evidence Repository™ is the central research resource supporting every publication, framework, professional programme, audit methodology, implementation model, and governance standard within the SAFECHAIN™ ecosystem.
The Repository enables visitors to understand not only what SAFECHAIN™ concludes, but the evidence that informs those conclusions. Each hub page in the Repository corresponds to a distinct category of evidence. Within each hub, individual entries are added over time as the Repository grows — creating a scalable, navigable knowledge architecture that connects evidence to frameworks, frameworks to professional guidance, and professional guidance to implementation.
This page is part of the SAFECHAIN™ Evidence Repository™ architecture. Contact samantha@safe-chain.org to suggest additions or to contribute to the Repository's development.

ABOUT THIS HUB
Official statistics and national data sets provide the quantitative foundation for the SAFECHAIN™ Economic Model™ (ECON-001) and the evidence base across the EERS™ Series. They are the empirical bedrock of the governance reform argument — the documented scale of domestic abuse, economic abuse, safeguarding system demand, and institutional cost that makes the SAFECHAIN™ economic case not a theoretical projection but a measurement-grounded analysis.
This hub catalogues the cornerstone statistical sources most directly relevant to the SAFECHAIN™ programme. The ECON-001 Reference Annex (available on request) identifies the specific data points drawn from each source.
CORNERSTONE STATISTICS AND DATA
OFFICE FOR NATIONAL STATISTICS — DOMESTIC ABUSE IN ENGLAND AND WALES
The ONS annual bulletin on domestic abuse in England and Wales (drawn from the Crime Survey for England and Wales and police recorded crime data) is the primary population prevalence source for domestic abuse statistics referenced throughout the SAFECHAIN™ programme. Key figures include the approximately 2 million adults experiencing domestic abuse annually, the 5 to 10 percent of adults experiencing domestic abuse at some point in their lives, and the gender breakdown of victimisation. SAFECHAIN™ Companion: ECON-001; WHITE-005; PROTO-004; DEPLOY-001.
HOME OFFICE — POLICE RECORDED CRIME — DOMESTIC ABUSE STATISTICS
The Home Office's annual domestic abuse statistics — covering police-recorded domestic abuse offences, outcomes, and MARAC referrals — provide the policing sector volume data for the SAFECHAIN™ economic analysis. Key data include the approximately 900,000 domestic abuse-flagged offences recorded annually, the clear-up rates, and the proportion resulting in charge or summons. SAFECHAIN™ Companion: ECON-001 Section 3.2; GUIDE-005; BENCH-001; NVI-004.
NHS ENGLAND — HOSPITAL ADMITTED PATIENT CARE AND A&E STATISTICS
NHS England's hospital activity statistics — including A&E attendance data coded for domestic abuse and hospital admissions attributable to domestic abuse — provide the healthcare volume data for the SAFECHAIN™ delay escalation analysis. The King's Fund analysis drawing on NHS data (approximately 2.4 million domestic abuse-related A&E attendances annually) is the primary healthcare cost evidence source. SAFECHAIN™ Companion: ECON-001 Section 3.3; DEPLOY-004 (Briefing Card 5); BENCH-001.
MINISTRY OF JUSTICE — FAMILY COURT STATISTICS
The MoJ's quarterly family court statistics provide volume data for the SAFECHAIN™ analysis of legal aid and court costs in the domestic abuse context — including the number of applications for non-molestation orders, occupation orders, and financial remedy proceedings. The data on cases with domestic abuse allegations and the time from application to disposal are relevant to the SAFECHAIN™ delay escalation analysis in the courts context. SAFECHAIN™ Companion: ECON-001 Section 3.5; GUIDE-001; NVI-007; NVI-008; NVI-009.
MINISTRY OF HOUSING, COMMUNITIES AND LOCAL GOVERNMENT — LOCAL AUTHORITY HOUSING STATISTICS
MHCLG's local authority housing statistics — including the homelessness data underlying the SAFECHAIN™ transition failure cost analysis — provide the quarterly volume data on domestic abuse-related homelessness presentations, temporary accommodation placements, and statutory homelessness outcomes. The estimated average cost per statutory homelessness episode (£24,000 to £36,000) cited in ECON-001 is drawn from MHCLG analysis. SAFECHAIN™ Companion: ECON-001 Section 2.3; GUIDE-002; NVI-009; BENCH-001.
DEPARTMENT FOR EDUCATION — CHILDREN IN NEED CENSUS AND LOOKED AFTER CHILDREN STATISTICS
DfE's Children in Need (CIN) Census and Looked After Children (LAC) statistics provide the annual volume data for the SAFECHAIN™ children's services cost analysis — including the number of children subject to child protection plans where domestic abuse is a factor, and the cost of looked-after children placements. The approximately 60 percent of child protection assessments in which domestic abuse is identified (from DfE data) is the primary evidence source for the SAFECHAIN™ analysis of children's services delay escalation costs. SAFECHAIN™ Companion: ECON-001 Section 3.4; GUIDE-004; SIS-004; SIS-006.
CROWN PROSECUTION SERVICE — DOMESTIC ABUSE AND VIOLENCE AGAINST WOMEN AND GIRLS REPORT
The CPS annual VAWG report provides charging, prosecution, and conviction data for domestic abuse offences — including the proportion of cases where the complainant supports prosecution and where charges are dropped. The data on complainant attrition — which the SAFECHAIN™ programme connects to the repeat disclosure burden and participation integrity failures — is directly relevant to the GUIDE-005 police guidance and the NVI-002 consent architecture. SAFECHAIN™ Companion: GUIDE-005; NVI-002; Participation Integrity™ (GLOSS-001); ECON-001 Section 4.3.
SURVIVING ECONOMIC ABUSE — EA50 ECONOMIC ABUSE SURVEY DATA
SEA's landmark EA50 survey (2020, with subsequent updates) provides the first systematic quantitative data on the scale and financial impact of economic abuse in the UK. Key findings — including the estimated £14 billion annual financial harm, the median financial loss per survivor, and the proportion experiencing credit damage — are primary data sources for the SAFECHAIN™ Legacy Harm Architecture™ analysis and the NVI-006 through NVI-009 economic returns modelling. SAFECHAIN™ Companion: ECON-001 Section 6.2; NVI-006; NVI-007; Legacy Harm Architecture™ (GLOSS-001).
SAFECHAIN™ BENCHMARK PROGRAMME — FUTURE DATA SOURCE
As the SAFECHAIN™ Benchmark Programme (BENCH-001) becomes operational through the pilot programme and national rollout, the aggregate, anonymised network performance data it generates will become a primary data source for the SAFECHAIN™ evidence base — specifically for the operational validation of the ECON-001 prevention return estimates and for the ROADMAP-001 long-term outcome studies. The National Benchmark Analysis, published annually through the REPORT-001 Annual Report process, will be catalogued in this hub from Year 1 of network operation. SAFECHAIN™ Companion: BENCH-001; REPORT-001; ECON-001; ROADMAP-001.
HOW TO USE THIS HUB
Official statistics are available through the publishing department's website and through the ONS website (ons.gov.uk). The SAFECHAIN™ ECON-001 Reference Annex — which identifies the specific data points drawn from each statistical source, the assumptions applied, and the calculations performed — is available on request. SAFECHAIN™ Companion references identify the most directly connected publications.
Individual data source pages will be added beneath this hub as the Repository develops.
