Childhood adversity costs England and Wales billions in health and economic impacts, new research finds

Childhood adversity costs £115.6 billion in England and £7.8 billion in Wales in health burden and premature death, according to October 2026 research analyzing data from 28,449 adults. Representing 5% of England's GDP and 8.4% of Wales's GDP, these costs stem primarily from mental illness and smoking. About half of adults report childhood trauma, which is linked to elevated rates of drug use and violence. Frameworks like Trauma-informed Wales aim to improve support.

Economic costs of childhood adversity

• ▪Regional cost estimates across England for health effects linked to childhood adversity ranged from £6.3 billion in the North East to £18 billion in the South East.
• ▪In England, estimated financial costs from adverse childhood experiences were £37.8 billion for mental illness and £22.7 billion for smoking, while in Wales each accounted for £1.8 billion.
• ▪A BMJ Open study published in October 2026 estimates health effects associated with childhood adversity cost £115.6 billion in England and £7.8 billion in Wales in 2023.
• ▪The monetary costs associated with adverse childhood experiences in 2023 represented 8.4% of Wales's gross domestic product and 5% of England's gross domestic product.

Associated health and social risks

• ▪Adults exposed to childhood adversity face heightened risks of mental illness, chronic physical conditions, health-harming behaviors, and poorer education and employment outcomes.
• ▪A study in BMJ Open associated childhood adversity with 60% of drug use in Wales, 57% in England, 49% of violence in Wales, and 46% in England.

Prevalence and trends of adversity

• ▪Approximately half of adults in England and Wales report experiencing at least one adverse childhood experience, while about 10% report four or more.
• ▪Evidence indicates that while some adverse childhood experiences may be declining in the UK, experiences like verbal abuse and household mental illness are less addressed and may be increasing.

Study methodology and limitations

• ▪Researchers analyzed seven causes of ill health and four health risks using Global Burden of Disease study data and UK government estimates of willingness to pay to reduce ill health.
• ▪The study authors noted limitations including measuring societal valuation rather than direct public spending, identifying associations rather than causation, and omitting prison populations.
• ▪Researchers combined data from 10 studies conducted across England and Wales between 2012 and 2024 involving 28,449 adults to model population-level health impacts.

Prevention of childhood adversity

• ▪Preventing childhood adversity can be achieved by supporting parents, building life skills, challenging harmful social norms, and addressing social pressures on families.
• ▪Reducing childhood trauma exposure improves lifelong health while potentially lowering broader societal monetary costs associated with premature death and disease.

Trauma-informed support approaches

• ▪The Trauma-informed Wales Framework establishes a societal approach to understanding and responding to trauma, recognizing how past experiences shape adult needs and behavior.
• ▪Trauma-informed support approaches aim to provide effective support for affected individuals by accounting for how past adversity impacts ongoing service interaction and behavior.
