Eating alone is not automatically lonely. A quiet breakfast can be a relief. A solo lunch can be practical. A dinner by oneself can be chosen, restful and perfectly ordinary. The new finding is not that every meal needs company. It is that, at population scale, the disappearance of shared meals may be catching something important about social life.

In a 2025 World Happiness Report chapter, Jan-Emmanuel De Neve of the University of Oxford, Andrew Dugan of Gallup, Micah Kaats of Harvard Kennedy School and Alberto Prati of University College London used global survey data and the American Time Use Survey to examine how often people eat with others and how that relates to subjective wellbeing.

The title number comes from the United States part of the analysis. In 2023, about 26% of American adults said they had eaten all of their meals alone on the previous day. The authors report that this was a 53% rise from 2003, based on roughly two decades of time-use data. The association with happiness was large enough that meal sharing sat beside income and unemployment as a surprisingly strong predictor of life satisfaction.

A simple measure of connection

The chapter appears in the World Happiness Report 2025, whose theme was caring and sharing. The meal-sharing chapter is useful because it studies something more concrete than many social-connection measures. Instead of asking people how close they feel to others, the surveys asked about behavior: how often they ate lunch or dinner with someone they knew.

That matters because loneliness, belonging and social support are psychologically important, but they are also subjective. People interpret them differently across ages, cultures and circumstances. A shared meal is still self-reported, but it is easier to compare than a feeling of closeness. Either lunch happened with another person, or it did not.

The authors used Gallup World Poll data from 2022 and 2023 covering more than 150,000 people in 142 countries and territories. Respondents were asked how many days in the previous week they ate lunch or dinner with family, friends or someone else they knew. The same chapter then turned to the United States, where the American Time Use Survey has tracked what people did the day before, and who they were with, from 2003 onward.

The American trend is not just the pandemic

The United States data showed a steady move toward solitary meals. The highest levels were not confined to 2020 and 2021. According to the report, rates of eating every meal alone were even higher in 2023 than during the pandemic years.

Living alone explains part of that shift, but not all of it. The authors note that people in one-person households were much more likely to eat alone, yet dining alone also rose among people who lived with others. In 2023, about 18% of Americans living with other people still reported eating every meal alone the previous day, up from about 12% in 2003.

That distinction is important. If the entire trend were simply about more people living by themselves, the social meaning would be narrower. But an increase among people who share a household suggests that schedules, work patterns, habits, devices, commuting, family routines and the organisation of daily life may all be part of the story.

The report also points to a sharp increase among younger adults. People over 65 were still more likely to eat alone overall, but the relative rise since 2003 was especially large among adults under 35. That finding deserves caution, because the analysis does not identify a single cause. It does, however, make the trend harder to dismiss as only a feature of old age or widowhood.

What the happiness link actually means

The strongest claim in the chapter is not that shared meals cause happiness. The authors are careful on that point. They report associations, not a resolved causal pathway. Happier people may be more likely to organise meals with others. Shared meals may also help people feel happier. Both could be true, and the report says more research is needed to separate those directions.

Even with that caveat, the association was striking. Globally, sharing more meals was linked with higher life evaluations, more positive affect and lower negative affect. In the United States, Americans who ate all meals alone reported life evaluations about half a point lower, on a zero-to-10 ladder, than Americans who shared at least one meal.

The researchers tested whether the relationship was merely a proxy for money, work, education or household size. In the global analysis, the connection between meal sharing and wellbeing remained after controlling for gender, age, education, employment, income, household size, country fixed effects and whether people had enough money to buy food.

That is where the comparison with income and unemployment enters. The chapter reports that knowing whether people shared meals explained differences in wellbeing about as strongly as knowing whether they were unemployed or where they fell in the income distribution. For positive emotions, meal sharing performed especially strongly.

Food may be doing social work

It is tempting to treat the meal as incidental, as if the real variable were simply “time with people.” But meals are a particular kind of social activity. They are scheduled, repeated, bodily and often low stakes. People do not have to announce that they are building social support. They can just sit down and eat.

That may be why a meal is such a useful marker. It captures not only whether another person is technically present, but whether daily life has enough coordination for people to pause in the same place at the same time. A shared meal can contain conversation, obligation, care, boredom, humour and routine. It is not always joyful, but it is social infrastructure at table height.

The wider literature gives the idea some context. In a 2010 PLOS Medicine meta-analysis, Julianne Holt-Lunstad, Timothy Smith and J. Bradley Layton found that stronger social relationships were associated with lower mortality risk. That paper was not about meals specifically, but it helps explain why researchers keep returning to ordinary social contact as a health and wellbeing question.

The meal-specific literature is still thinner. The World Happiness Report chapter cites a 2021 systematic review in the International Journal of Environmental Research and Public Health on in-home eating and shared meals, as well as a BMC Geriatrics study that found an association between eating alone and depressive symptoms among older adults in China. These studies vary in design and population, so they should not be read as one simple causal story.

The quality of the meal still matters

A shared meal is not automatically supportive. A tense dinner can be worse than a peaceful one alone. A meal eaten with someone while both people stare at their phones may not carry the same social benefit as an actual conversation. The report itself notes that the quality of interaction, the kind of meal and other confounding factors were not deeply examined.

That limitation matters because a policy or personal lesson based only on the count of shared meals could become clumsy. The point is not to shame people who live alone, work odd hours, parent by themselves, recover from social exhaustion or prefer some solitude. The point is that daily eating patterns may reveal whether a society is making ordinary togetherness easy or hard.

Technology may also change the meaning of “together.” A meal with another person is not the same experience if attention is repeatedly pulled away. In a 2018 Journal of Experimental Social Psychology study, Ryan Dwyer, Kostadin Kushlev and Elizabeth Dunn found that smartphone use during face-to-face social interactions reduced enjoyment. The study does not explain the national dining trend, but it is a reminder that physical co-presence and social attention are not identical.

A small habit, a large signal

The report’s most careful reading is also the most useful one. Shared meals are not a cure for loneliness, and eating alone is not a diagnosis. But the regularity of eating makes it a sensitive signal. If people are drifting out of shared meals, they may also be drifting out of other repeated forms of contact that are too ordinary to notice until they are gone.

That is why the 26% figure is striking. It does not say that one in four American adults is unhappy. It says that one in four reported going through the previous day without sharing any meal with another person. Across a population, that is not just a food habit. It is a clue about how everyday social life is being arranged.

The open scientific question is causal: whether more shared meals would improve wellbeing, whether better wellbeing makes shared meals easier, or whether both are downstream of deeper conditions such as work schedules, housing, family structure and social trust. For now, the evidence is strong enough to make the humble shared meal look less like nostalgia and more like a measurable part of human connection.
