You Can Be Surrounded by People and Still Feel Lonely

What one of the largest studies of loneliness tells us about connection, community and belonging

By Lydia@Lydia.com

You can live in a crowded city.

Have colleagues.

Know your neighbours.

Exchange messages all day.

Have hundreds of contacts stored in your phone.

And still feel lonely.

That apparent contradiction is one of the most important lessons emerging from modern research into social connection.

Loneliness is not simply the absence of people.

It is the feeling that the relationships we have do not provide the connection we need.

And a remarkable new study from England is helping researchers understand just how complicated that experience can be.

One of the largest studies of loneliness

The Measuring Loneliness in England (INTERACT) Study surveyed 135,725 adults aged 16 and over.

Researchers used established measures including the UCLA three-item Loneliness Scale and the Office for National Statistics' direct measure of loneliness. They also asked about friendships, family contact, neighbourhood trust and social support.

Among the people who responded, 16.5% said they felt lonely often or always.

Around 21% said they often felt left out, 21.9% frequently lacked companionship and 22.5% often felt isolated from others.

Those are striking numbers.

But there is an important qualification.

The researchers repeatedly caution that the participants were volunteers rather than a representative sample of the English population. Women, older adults and university-educated people were over-represented. The findings therefore describe the people who took part and should not be treated as national prevalence estimates.

That scientific caution matters.

Fortunately, other research confirms that loneliness is far from rare. The World Health Organization's Commission on Social Connection estimates that roughly one person in six worldwide experiences loneliness, with particularly high levels among adolescents and young adults.

Loneliness and being alone are not the same thing

Perhaps the most useful distinction in the INTERACT paper is between loneliness and social isolation.

Social isolation describes something comparatively objective: having relatively few relationships or interactions.

Loneliness is subjective.

It describes the gap between the connection we have and the connection we would like to have.

The researchers point out that someone can possess an extensive social network and nevertheless feel profoundly lonely if emotional closeness is missing.

Another person may have only a few close relationships and feel deeply connected because those relationships provide trust, understanding and support.

That explains something many of us have probably experienced.

Being alone can sometimes feel wonderful.

A quiet Sunday morning.

Reading.

Gardening.

Walking.

Simply having time to think.

Loneliness is different.

It is solitude we did not choose—or connection that somehow does not feel like connection.

The strange loneliness of crowded places

The INTERACT researchers also explored geography.

Among their respondents, higher loneliness scores appeared clustered in major urban centres including London, Birmingham and Manchester. Because of the study design, the researchers stress that this does not establish that people living in those cities are more lonely overall.

Still, the finding connects with an intriguing idea in earlier research: the urban paradox.

A city can contain millions of people while providing surprisingly few opportunities for meaningful connection.

We may live beside hundreds of neighbours without knowing their names.

Take an elevator without speaking.

Travel on a crowded train surrounded by strangers.

Work beside people whose lives remain almost completely unknown to us.

Physical proximity is not the same thing as belonging.

Your neighbourhood may matter more than you think

This is where the INTERACT study becomes especially interesting.

Researchers did not examine loneliness only as an individual psychological experience.

They also asked about what sociologists call social capital: trust, reciprocity, neighbourhood cohesion and the belief that people around us might help when needed.

Among respondents, 58.9% agreed that people in their neighbourhood could generally be trusted, while 51.7% agreed that neighbours were willing to help one another. Views were considerably more divided over whether neighbourhoods actually felt close-knit.

Other research supports the importance of these everyday neighbourhood relationships.

A longitudinal U.S. study involving 5,817 adults aged 50 and older found that increases in people's perceptions that their neighbours were trustworthy and helpful were associated over time with lower loneliness and greater perceived support from friends.

Perhaps belonging begins closer to home than we sometimes imagine.

Don't underestimate the people you barely know

Close friendships are enormously important.

But psychologists have also become interested in our weak ties.

These are not best friends.

They are the people at the edges of our lives.

The woman who walks her dog at the same time every morning.

The receptionist at your doctor's office.

Someone you regularly see at the coffee shop.

A neighbour three houses away.

The colleague from another department whom you occasionally meet in the elevator.

Research by Gillian Sandstrom and Elizabeth Dunn found that interactions with these more peripheral members of our social networks were associated with greater feelings of happiness and belonging.

More recent research suggests that a mixture of strong and weak social ties may be valuable: close relationships provide intimacy and dependable support, while weaker ties can offer novelty, engagement and access to wider communities.

They do not replace close friendship.

But they may make the world feel less anonymous.

Why the pandemic still matters

The INTERACT survey also captured the lingering social shadow of COVID-19.

Among respondents, 44% said the pandemic and lockdowns had increased their loneliness, while 48.2% reported increased isolation. The researchers appropriately caution that these were retrospective recollections rather than measurements taken before and after lockdown, so cause and effect cannot be established.

Yet the experience demonstrated how quickly ordinary social infrastructure can disappear.

Workplace conversations.

School gates.

Coffee shops.

Libraries.

Religious communities.

Clubs.

Sport.

Neighbours stopping for a conversation.

Many of these interactions seemed almost trivial until they vanished.

Sometimes we recognise the architecture of belonging only after parts of it have been removed.

Loneliness does not belong to one generation

There is another stereotype worth abandoning.

Loneliness is often portrayed as primarily a problem of old age.

Older people certainly face particular risks, including bereavement, declining health and reduced mobility. But the INTERACT authors emphasize that loneliness occurs across the life course, and they specifically caution against viewing it only through the lens of ageing.

Current British population data point in the same direction. In early 2026, the Office for National Statistics reported that 23% of adults felt lonely often, always or some of the time, with younger adults among those more likely to report loneliness.

A twenty-five-year-old surrounded by colleagues can be lonely.

So can a new mother.

A recently divorced woman.

Someone caring for an ageing parent.

A person who has moved to a new city.

An immigrant adjusting to another culture.

A widow after fifty years of marriage.

Loneliness is not an age.

It is a human experience.

Connection is also a health issue

The growing scientific interest in loneliness is not simply about happiness.

WHO now describes social connection as an important component of health and reports associations between loneliness and poorer mental and physical health outcomes. Its Commission on Social Connection has called for social health to receive greater attention alongside physical and mental health.

This does not mean loneliness inevitably makes someone ill.

Human health is far more complicated than that.

But it does mean relationships deserve to be regarded as more than optional extras.

Friendship.

Family.

Neighbours.

Community.

The feeling that somewhere, someone notices whether we are there.

These things matter.

Perhaps connection begins very small

The scale of the loneliness problem can make solutions sound impossibly grand.

Perhaps some of them are.

Cities can design better public spaces.

Communities can create places where people naturally meet.

Healthcare systems can recognise social disconnection.

Employers can think differently about belonging.

But our own contributions can be surprisingly modest.

Say hello.

Learn someone's name.

Call the friend you've been meaning to call.

Invite someone for coffee.

Talk to the person sitting beside you.

Ask your neighbour how she is—and wait long enough to hear the real answer.

None of these actions guarantees friendship.

But friendship has to begin somewhere.

Lydia's™ Take

Perhaps the opposite of loneliness isn't having a crowded calendar.

It isn't having hundreds of contacts.

And it certainly isn't having thousands of followers.

Perhaps it is much simpler.

Knowing there are people with whom you can be yourself.

Someone who notices when you've disappeared for a while.

Someone you can call without wondering whether you're bothering them.

A neighbour who would collect some groceries if you were sick.

A friend who remembers something you told her three weeks ago.

And perhaps a community where saying hello still means something.

Technology can help us find one another.

But belonging is something human beings still have to build.

One conversation.

One friendship.

One small act of recognition at a time.
