1. Main stories

The statistics show:

  • expenditure on health and disability benefits is forecast to continue increasing
  • expenditure on PIP has increased more quickly than expected
  • changes in the population will increase the number of adults requiring health and disability support
  • not all increases in the health and disability benefit caseload have come from an ageing population

2. Expenditure on health and disability benefits is forecast to continue increasing

Working age health and disability spend - including benefits devolved to Scotland

Source: Benefit expenditure and caseload tables

Spending on working age PIP/DLA is forecast to rise to £19bn annually, while spending on ESA/UC* is forecast to rise to £21bn annually.

In today’s money the amount spent on health and disability income replacement benefits has fluctuated, and is forecast to rise over the coming years.

The total amount of money paid to people receiving working age health and disability benefits is forecast to reach a record £40bn in today’s money by 2025 to 2026.

The block grant adjustment for working age PIP and DLA in Scotland has been included in forecast years, as these benefits have been devolved to the Scottish Government.

Working age health and disability expenditure as percentage of GDP

Source: Benefit expenditure and caseload tables

Spend on incapacity benefits as a proportion of GDP has varied over time, but has continuously increased for disability benefits.

Spending on working age incapacity and working age disability benefits is expected to be 1.5% of Gross Domestic Product (GDP) in 2021 to 2022, and is expected to rise to 1.6% of GDP by 2025 to 2026. This is an increase from 1.3% of GDP in 2019 to 2020.

GDP is a measure of the volume of goods and services produced in the economy. It is a measure of the size of the country’s economy.

In the mid-1990s, spending on working age incapacity and disability benefits was 1.5%, indicating overall spending as a proportion of GDP had reduced until 2020 to 2021. Part of the reason for the increase in this spending as a proportion of GDP is that the value of GDP fell in 2020 to 2021. This means that spending on these benefits, which did not reduce, is now a bigger proportion.

Expenditure on working age income replacement benefits

Source: Benefit expenditure and caseload tables

Spending on means-tested benefits to support people whose health limits how much they can work has been rising.

Real terms total spending on incapacity benefits declined from £19bn in 2001 to 2002 to £16bn in 2008 to 2009, before increasing to £17bn by 2019 to 2020. Real terms spending is now expected to increase every year to 2025 to 2026

From the early 1990s onward spending has been gradually shifting away from contribution-based benefits to means-tested ones.

We are forecast to have an approximate increase of £6bn of spending on these benefits in the next 5 years, including increases in expenditure on UC* which is replacing means-tested ESA.

3. Forecast expenditure on PIP has increased more quickly than expected

Meanwhile the forecast combined working age PIP and DLA spend has risen.

Actual and forecast spends on working age PIP and DLA claimants in real terms as reported in the 2014, 2016, 2018 and 2021 budgets, as well as the 2012 autumn statement. The actual spend is shown with a solid line and forecast ones are dashed.

According to the 2021 forecast, combined PIP and DLA spending on working age claimants is forecast to increase from £12.5bn in 2019 to 2020 to £18.6bn in 2025 to 2026, about a 48% real terms increase in 6 years.

4. Changes in the population will increase the number of adults requiring health and disability support

Recent population changes have increased the number of people aged over 50.

Between 2015 and 2020, the working age population of GB increased by 5%.

The increase has been accompanied by an ageing of two large age groups in the working population, namely those aged 30 to 40 and those aged 50 to 60. Alongside this, increases in the state pension age mean more people are now included as working age when aged over 60.

Over the next 10 years, changes in the population are predicted to increase the number or people aged over 60.

By 2029, the total working age population is projected to increase by 4% with the number of people aged 55 and over and of working age increasing by 17%. This increase in older cohorts will be caused in part by the increase in State Pension age.

People acquire more health conditions as they get older. The growth in this oldest working age cohort will increase the number of adults requiring health and disability support.

5. Not all increases in the health and disability benefit caseload have come from an ageing population

The proportion of people at each age receiving ESA/UC* by gender

Source: Shaping Future Support Green Paper evidence pack and ONS population estimates

The proportion of people at each age who receive ESA/UC* has decreased for most ages, except for those nearing State Pension age.

As people get older, they can be expected to experience more health conditions, and the proportion of these people receiving health and disability benefits can also be expected to increase.

For women between the ages of 20 and 40 there has been a slight increase in the proportion receiving income replacement health and disability benefits between 2015 and 2020. For women aged between 40 and 60 the proportion who receive income replacement health and disability benefits at each age was very similar in 2015 and 2020.

At most ages below 62, the proportion of men receiving an income replacement health and disability benefit has fallen between 2015 and 2020.

For women aged over 60, and men aged 62 and older, the increasing State Pension age has meant that many more people of these ages were receiving working age income replacement health and disability benefits in 2020 compared to 2015.

The proportion of people at each age receiving PIP/DLA by gender

Source: Benefit combination tables and ONS population estimates

The proportion of people at each age who receive PIP/DLA has increased, particularly for women and men aged 16.

The proportion of men and women aged under 40 receiving extra costs health and disability benefits has increased for all ages between 2015 and 2020.

This increase means that a higher proportion people aged under 40 were receiving extra costs health and disability benefits in 2020 than 5 years earlier. Since 2013 PIP has been replaced by DLA as the working age extra costs health and disability benefits, and PIP is designed to ensure parity between physical and mental health conditions. A higher percentage of young people compared to older people, report experiencing mental health disorders[footnote 1].

At older ages, the increasing State Pension age has means that a higher proportion of men and women aged over 62 were receiving working age extra costs health and disability benefits in 2020 compared to 2015.

6. An increasing share of working age people have health problems, including mental health problems

Disability prevalence is increasing in the working age population.

The prevalence of disability in the working age population has increased by 5 percentage points in a decade. In 2008 to 2009, 14% of the working age population were disabled. In 2018 to 2019, this figure was 19%.

The proportion of working age people with mental health conditions

Source: Adult Psychiatric Morbidity Survey, the Family Resources Survey and Annual Population Survey

The proportion of working age people with mental health conditions has been increasing in both surveys and clinical studies.

The Adult Psychiatric Morbidity Study (APMS) uses a Clinical Interview Schedule (CIS-R) score to represent severity of overall neurotic symptoms, with a higher score indicating more severe symptoms.

Over four waves of this study the proportion of working age people with common mental disorders recorded in the APMS has increased from 14% in 1993 to 18% in 2014.

The proportion of working age people who self-report a disability in the Family Resources Survey, and who report mental health difficulties has increased from 5% in 2010 to 10% in 2019.

The proportion of working age people who self-report mental health and learning difficulties in the Annual Population Survey has increased from 2% 2005 to 6% in 2019.

7. An increasing proportion of people receiving ESA and PIP have a mental or behavioural disorder

Source: Shaping Future Support Green Paper evidence pack

Approximately 50% of people receiving ESA have a primary condition which is a mental or behavioural disorder.

The ICD10 codes for mental and behavioural disorders are made up of the following categories of conditions: organic, including symptomatic, mental disorders including Alzheimer’s disease, dementia and brain damage; mental and behavioural disorders due to psychoactive substance use; schizophrenia, schizotypal and delusional disorders; mood [affective] disorders including manic episodes, bipolar disorder, and depressive disorders; neurotic, stress-related and somatoform disorders including anxiety disorders, obsessive disorders, stress disorders and dissociative disorders; behavioural syndromes associated with physiological disturbances and physical factors; disorders of adult personality and behaviour; mental retardation; disorders of psychological development; behavioural and emotional disorders with onset usually occurring in childhood and adolescence; and unspecified mental disorder.

The proportion of people receiving Incapacity Benefit (IB) and Employment and Support Allowance (ESA) who have a mental or behavioural disorder as their primary condition has been increasing, from 32% in 2000 to 51% in 2018.

Source: PIP and DLA caseload tables

Approximately 40% of working age people receiving PIP or DLA now have a primary condition which is a mental or behavioural disorder.

The principal classification systems for PIP and DLA differ to the ICD10. This data uses the ICD10 classification for the primary condition of people receiving PIP or DLA.

The proportion of working age (WA) people receiving PIP or DLA who have a mental or behavioural disorder as their primary condition has been increasing, from 25% in 2002 to 41% in 2020.
