Loneliness in numbers

The facts and statistics

Loneliness is a part of life and something that most of us experience at some point. But when loneliness is severe or lasts a long time, it can have a negative impact on our health and well-being.

Recent studies suggest that long-term loneliness is one of the largest health concerns we face. It is as harmful as obesity or smoking 15 cigarettes a day. Feeling lonely can lead to depression, anxiety, disrupted sleep and stress. It can also be a factor in heart disease, increased blood pressure and degenerative brain diseases such as Alzheimer’s.

Long-term loneliness has serious health implications

Loneliness is likely to increase your risk of death by 26%. [1]

Loneliness is worse for you than obesity. [2]

Loneliness is a risk factor for depression in later life. [3]

Loneliness and social isolation put individuals at greater risk of cognitive decline and dementia. [4]

Loneliness and social isolation have been linked to a 30% increase in the risk of having a stroke or coronary artery disease. [5]

Loneliness affects people of all ages

16-29-year-olds are twice as likely as those over 70 to experience loneliness. [6]

Characteristics of people who are more likely to experience loneliness include those who are widowed, those with poorer health, and those with long-term illness or disability. [3]

In total, 45% of adults feel occasionally, sometimes, or often lonely in England. This equates to twenty-five million people. [7]

Disconnected communities could be costing the UK economy £32 billion every year. [8]

The number of over-50s experiencing loneliness is set to reach two million by 2025/6. This compares to around 1.4 million in 2016/7 – a 49% increase in 10 years. [9]

Half a million older people go at least five or six days a week without seeing or speaking to anyone at all. [10]

Two-fifths of all older people (about 3.9 million) say the television is their main company. [11]
