Loneliness Persists for One in Six Adults in England, New Study Finds

Study Overview
Researchers at Imperial College London surveyed 135,725 volunteers aged 16 and older across England during a five-month online data collection period in 2023. The INTERACT study, described as one of the world’s largest dedicated investigations of loneliness, found that almost one-in-six adults reported feeling lonely “often or always.” More than one-in-five participants frequently experienced a lack of companionship or feelings of being left out or isolated.
Demographic and Geographic Findings
The sample was 62 % female, 83 % White, and included a substantial proportion of older adults (32 % over 65). Forty-five percent were married or in a civil partnership, while roughly 20 % were single. Geographic analysis revealed clusters of the highest loneliness scores in major urban centres—London, Birmingham and Manchester—supporting the “urban paradox” theory that city dwellers may enjoy economic and cultural advantages yet report lower life-satisfaction and social connectivity than rural residents.
Impact of the COVID-19 Pandemic
Nearly 44 % of respondents indicated that the COVID-19 pandemic increased their feelings of loneliness, and 48.2 % reported heightened isolation. Researchers highlighted that these lasting effects span all adult age groups, not solely older populations.
Public Health Implications
Austen El-Osta, Ph.D., study lead, emphasized that loneliness should be treated as a public-health and community issue rather than a private experience. Senior author Dr Azeem Majeed, an NHS GP, noted that loneliness contributes to anxiety, depression, increased risk of long-term conditions, and more frequent GP consultations, underscoring the need for place-based interventions that strengthen social capital.
Study Limitations and Gaps
The researchers cautioned that the online, self-selected survey design introduced inherent biases: highly educated individuals were over-represented, while minority ethnic groups were under-represented. Consequently, the findings cannot be used to estimate the national scale of loneliness, and the most isolated individuals—who may be less likely to engage online—could be missing from the data.
Verbatim Quote
“The key message is not simply that many people feel lonely, but that loneliness is strongly influenced by people’s surroundings, social network and their environment.” — Ph. D
Background & Context
In 2023, the World Health Organization classified loneliness as a global public-health problem affecting all age groups. The INTERACT study builds on earlier work such as the 2018 BBC Loneliness Experiment, which surveyed 55,000 people worldwide, by providing a detailed, England-wide dataset that links loneliness to neighbourhood trust, social capital and place.
Conflicting Reports & Gaps
While the INTERACT study offers a comprehensive snapshot, its authors acknowledge that the sample’s demographic skew limits the ability to generalise findings to the entire English population. No alternative large-scale studies of comparable scope were cited, leaving a gap in population-level estimates of loneliness prevalence.
What’s Next
The research team suggests incorporating routine loneliness screening into primary-care assessments and developing coordinated, place-based public-health strategies to mitigate the identified urban clusters of loneliness.
