The lockdowns are gone, restaurants are full and everyday life looks remarkably normal again. But a major new study from England raises a more difficult question: did all of our social connections come back with us?
There was a strange moment after the pandemic when life seemed to restart.
Offices reopened.
Restaurants filled again.
Airports became crowded.
Birthday parties returned.
We stopped measuring the distance between ourselves and the person standing beside us in the supermarket.
From the outside, normal life appeared to have resumed.
But human relationships are not light switches.
You cannot necessarily turn them off for months or years and expect them to illuminate exactly as they did before.
A large new study from England offers an intriguing glimpse of what happened to social connection in the aftermath of COVID-19.
And its findings suggest that although the lockdowns ended, for many people the experience of disconnection may have left a longer shadow.
One of England's Largest Studies of Loneliness
The Measuring Loneliness in England (INTERACT) Study, published in 2026 in BMC Global and Public Health, surveyed 135,725 adults.
Researchers used established measures of loneliness alongside questions about friendships, family contact, neighborhood trust and social support. They also mapped responses geographically to explore how loneliness and social connection varied across communities.
Among the people who responded:
16.5% said they felt lonely often or always.
Around 22% often felt they lacked companionship.
21% often felt left out.
And 22.5% often felt isolated from other people.
Those are substantial numbers.
But there is an important qualification.
The researchers do not claim that these percentages represent England as a whole.
People volunteered to participate, and the sample contained disproportionately more women, older adults and university-educated people than the wider population. The researchers repeatedly warn that their findings should therefore describe the people who responded rather than be used to estimate national rates of loneliness.
It is an important distinction.
A study can be very large without necessarily being representative.
But what the researchers found within those 135,725 lives is still worth considering.
COVID Left a Social Mark
The survey asked participants directly about the pandemic.
44% agreed that COVID-19 and the lockdowns had made them feel lonelier.
Almost half—48.2%—said they had made them feel more isolated.
We should be careful about what that tells us.
Participants were looking back on their pandemic experiences, and memory is imperfect. Because this was a cross-sectional study rather than one that followed the same people continuously before, during and after COVID, researchers cannot prove that the pandemic caused their subsequent loneliness. The authors explicitly acknowledge this limitation.
But the finding raises a question that may feel familiar.
When the world reopened, did our social lives reopen completely with it?
The Connections We Didn't Know We Had
Before COVID, much of our social life happened almost accidentally.
There was the woman you talked to while waiting for coffee.
The colleague who stopped beside your desk.
The neighbor you saw walking the dog.
The person who sat beside you at yoga.
The librarian who knew which books you liked.
The familiar face at the grocery store whose name you never actually learned.
None of these people might have been a close friend.
Yet collectively they helped create something important:
a feeling of being part of the world.
COVID temporarily removed enormous numbers of these ordinary encounters.
Video calls helped preserve some of our closest relationships. But scheduling a Zoom meeting with someone is very different from unexpectedly spending five minutes talking in a hallway.
When restrictions disappeared, some of those little rituals returned.
Others didn't.
We changed jobs. We moved. Businesses closed. Habits changed. Social groups dissolved. Some people continued working from home.
And perhaps some of us simply became accustomed to staying there.
Loneliness Is Not the Same as Being Alone
This distinction is central to understanding the research.
Scientists generally distinguish social isolation from loneliness.
Social isolation describes an objective shortage of relationships, interactions or social contact.
Loneliness is subjective: it occurs when there is a gap between the relationships we have and the relationships we feel we need.
That means a woman can live alone and not feel lonely.
Another can be married, work in a busy office, have hundreds of social-media contacts and still feel profoundly disconnected.
The INTERACT researchers make this point explicitly: people may have extensive social networks and still experience loneliness when emotional closeness is missing, while people with smaller networks may feel well connected when those relationships contain trust and support.
In other words:
Loneliness isn't simply about how many people are around us.
It is about whether those relationships feel meaningful.
This Is Not Just an English Problem
The INTERACT study provides an unusually large snapshot from England, but loneliness has become an international public-health concern.
In 2025, the World Health Organization's Commission on Social Connection estimated that approximately one in six people worldwide experiences loneliness.
Importantly, loneliness is not confined to old age. WHO's global estimates found the highest rates among adolescents and young adults, although people at every stage of life can be affected.
In the United States, CDC data similarly suggest that lack of connection is widespread: approximately one in three American adults reports feeling lonely, while about one in four reports lacking adequate social and emotional support.
The WHO now argues that social connection deserves to be considered alongside physical and mental health as an important component of human wellbeing.
That represents quite a change in how loneliness is understood.
It is no longer being treated simply as an unpleasant feeling.
It is increasingly being studied as a public-health and community issue.
The Paradox of the Lonely City
One of the most visually interesting parts of the INTERACT study is its map of England.
Researchers found clusters of higher loneliness responses around large urban areas including London, Birmingham and Manchester.
They appropriately caution that their sampling method means the map cannot tell us that people living in those cities are lonelier than people elsewhere.
But the researchers place their findings within a fascinating body of earlier work concerning what has been called the “urban paradox.”
A city can contain millions of people without necessarily creating meaningful social connection.
Population density is not intimacy.
Being surrounded by people is not the same as knowing them.
And having somewhere to go is not the same as having someone to go there with.
Perhaps We Have Been Measuring the Wrong Thing
This may be the most interesting part of the INTERACT study.
The researchers didn't merely ask people whether they were lonely.
They also asked about their neighborhoods.
Could neighbors be trusted?
Would they help one another?
Was the neighborhood close-knit?
If someone became sick, was there a neighbor who might collect groceries for them?
These questions measure aspects of what researchers call social capital—the networks of trust, reciprocity and cooperation that help communities function.
And that shifts the conversation.
Instead of asking only:
“What should a lonely person do?”
perhaps we should also ask:
“What kind of communities make it easier for people not to become lonely?”
The INTERACT authors argue that loneliness should be considered alongside community-level factors such as trust and cohesion, while appropriately cautioning that interventions intended to strengthen community connection still need rigorous evaluation.
Friendship Is Not a Number
Modern life gives us plenty of numbers.
Followers.
Contacts.
Likes.
Messages.
Friends.
But none tells us whether someone would notice if we were having a difficult week.
The CDC defines social connection more broadly than simply the size of a person's network. It includes the diversity of relationships we have, what those relationships provide, and importantly, their quality.
This helps explain why loneliness can coexist with apparently busy lives.
You can have plenty of interaction and very little intimacy.
And sometimes what is missing isn't another person to talk to.
It is someone with whom you can say what you actually mean.
Rebuilding Connection May Start Small
There is no single prescription for loneliness.
Its causes are too varied.
Divorce, bereavement, retirement, relocation, poor health, financial difficulty and changing family structures can all alter a person's social world. WHO specifically identifies major life transitions—including moving, job loss, relationship breakdown and bereavement—among the factors that can contribute to social disconnection.
And we should be cautious about promising that joining a club or calling an old friend will somehow “cure” loneliness.
But rebuilding connection does not necessarily require a dramatic reinvention of one's social life.
The CDC notes that small acts of connection can matter: checking on someone, contacting a friend, participating in community activities and deliberately strengthening existing relationships can all contribute to social connectedness.
Perhaps the first step is simply to notice the connections that have disappeared.
The friend we haven't called.
The neighbor whose name we still don't know.
The activity we stopped attending.
The colleague we used to have lunch with.
The invitation we keep meaning to accept.
Not every encounter will become a friendship.
It doesn't have to.
A connected life is built from many different kinds of relationships.
Lydia's™ Take
COVID taught us something strange about human connection.
We didn't fully appreciate many of our ordinary encounters until they disappeared.
The five-minute conversation.
The familiar face.
The unexpected invitation.
The person who remembered our name.
When the pandemic ended, we understandably wanted normality back.
But perhaps normality was never simply restaurants reopening and airplanes flying again.
Perhaps part of rebuilding was something quieter:
rebuilding the little human connections that made ordinary life feel inhabited.
The INTERACT study cannot tell us whether the pandemic permanently changed the way we relate to one another.
But it does remind us of something worth remembering.
You can be surrounded by people and still feel lonely.
You can have hundreds of contacts and still long for conversation.
And sometimes the difference between living among people and belonging among them begins with something remarkably small.
A question.
An invitation.
A cup of coffee.
A conversation that lasts five minutes longer than expected.
The pandemic ended.
Perhaps rebuilding connection is taking a little longer.
Editorial Note
The INTERACT study involved 135,725 adults in England and is one of the country's largest descriptive studies of loneliness and social disconnection. However, participants formed a volunteer, non-probability sample and were not representative of England's population. Its findings therefore describe the study participants and should not be interpreted as national prevalence estimates. Because the study was cross-sectional and participants retrospectively reported their experiences during COVID-19, it also cannot establish that the pandemic caused subsequent loneliness.
