People with severe intellectual disabilities live 24 years less on average than the general population, according to a new study from King's College London. This stark disparity highlights urgent gaps in healthcare access and quality for this vulnerable group.
Study Reveals Alarming Life Expectancy Gap
Researchers analyzed data from the Office for National Statistics and the LeDeR programme, examining deaths in England between 2021 and 2023. They compared 1,301 adults with severe or profound intellectual disability against 2,626 adults with mild or moderate intellectual disability and 536,311 adults from the general population who died in 2022.

The findings show that people with severe or profound intellectual disability died at an average age of 58, compared to 65 for those with mild or moderate disability and 82 for the general population. This 24-year gap is a call to action for policymakers and healthcare providers.
Avoidable Deaths and Leading Causes
Two in five deaths in the severe disability group were judged to be avoidable, defined as deaths before age 75 from preventable or treatable causes. Pneumonia and epilepsy were the leading avoidable causes, significantly higher than in other groups. Cerebrovascular disease also contributed notably.
| Group | Average Age at Death | Avoidable Deaths (%) |
|---|---|---|
| Severe/Profound Intellectual Disability | 58 | 40% |
| Mild/Moderate Intellectual Disability | 65 | Not specified |
| General Population | 82 | Not specified |
Ethnic Disparities Within the Group
Within the severe disability group, people from minority ethnic backgrounds died 14 years younger than their white counterparts. This double disadvantage compounds the existing health inequality and demands targeted interventions.
Expert Reactions and Systemic Failings
Jon Sparkes, CEO of learning disability charity Mencap, called the findings shocking but “sadly unsurprising.” He emphasized that “organisational failings were identified in more than 40% of deaths reviewed last year, showing the way the NHS just isn’t designed to work for people with a learning disability.”
Sparkes urged the government and NHS to consider these needs in new neighbourhood health schemes, digital transformation, and preventive health efforts. He stressed that only by addressing these systemic issues can we end the deep-rooted inequities.
Key Takeaways for Improving Care
- People with severe intellectual disabilities face a 24-year shorter life expectancy.
- 40% of deaths are avoidable, with pneumonia and epilepsy as top causes.
- Minority ethnic groups within this population face even worse outcomes.
- Healthcare systems must adapt to provide accessible, proactive care.
