In 2023, 1 in 6 people in the UK experienced some form of depression, yet a gap still shows up between need and support. In England alone, 1.1 million antidepressant items were prescribed in July 2023, while around 1 in 6 adults with depressive symptoms still did not receive any treatment in the 2014 Adult Psychiatric Morbidity Survey. We sift through these contrasts to show what depression costs, how it affects health beyond mental wellbeing, and what routes like IAPT and digital support can change.

Interpretation
Health Outcomes Interpretation
Within the health outcomes picture, depression is linked to major burdens and harm, from 5.8% of adults in England reporting a mental health problem affecting daily activities a lot in 2022 to depressive disorders accounting for 5.2% of years of life lost in the UK and suicide registrations reaching 5,783 deaths in 2023 in England.

Economic Impact Interpretation
In the Economic Impact context, the UK faced an estimated £3.9 billion in indirect productivity losses from depression in 2010 and then rising lost employment income of £8.2 billion in 2017, showing how common mental health problems drive substantial, non-trivial economic costs alongside their leading role in non-fatal burden.
