How many close friends does the average person have?
Count the people you'd ring at two in the morning, not the ones you'd invite to a wedding, and the number gets small fast. Most people have never checked that figure against anyone else's, so they carry a vague sense of being either well connected or a bit alone with no idea which is true. Put your count in with your age and sex and see where it sits against a national survey, and which of Dunbar's layers it belongs in. This calculator on Find The Norm uses Pew Research 2023 data (n=5,057), Survey Center on American Life 2021, and Dunbar (1992) network layers to rank your close-friend count against US adults in your age and gender cohort.

How many friends does the average person have?
Most American adults have between 1 and 4 close friends, roughly 50% of men and 55% of women in the Pew Research Center's 2023 survey of 5,057 US adults, where a close friend means someone you'd turn to for personal support rather than a colleague or a casual acquaintance. That definition is the one the calculator uses, so count against it. If you include the group chat and the people you see at the school gate, you'll rank high for the wrong reason.
| Age group | Reporting 5+ close friends (Pew 2023) |
|---|---|
| Under 30 | 32% |
| 30 to 49 | 34% |
| 50 to 64 | 40% |
| 65+ | 49% |
The table runs the opposite way to what most people expect. Older adults are more likely to report 5 or more close friends than younger adults, even though their overall networks are smaller, which fits socioemotional selectivity theory, where people put their effort into fewer relationships as they age and get clearer about who counts as close. So a 25-year-old with three close friends and a 70-year-old with three are in different positions on their own age curves, and the calculator asks for your age group because of that.
About 8% of adults in the Pew 2023 data report no close friends at all. That group is measurable and growing, especially among men, whose share with none rose from 3% in 1990 to 15% in 2021 in the Survey Center on American Life's figures. The argument frequency calculator looks at what goes on inside the close relationships people do have, and our adult friendship statistics page runs through the wider Pew figures.
Dunbar’s number and the layers of friendship
Robin Dunbar's work on social networks, published in Human Nature and developed since, describes human networks as nested layers, each with a typical size and a typical closeness. The layers are a gradient rather than boxes, and the calculator uses them to tell you which layer your count sits in, which is a framework placement rather than a percentile.
The innermost layer is the support clique of about 5 people, the ones you'd call first in a crisis and your most emotionally important relationships. Studies of who people contact first in bereavement or serious illness keep finding cliques of about that size. Next comes the sympathy group of about 15, whom Dunbar defines as the people whose death would greatly distress you, which is blunt but precise.
Beyond that sits an affinity group of around 50 and then the active network of around 150, the figure most people know as Dunbar's number. The 150 is thought to be the cognitive ceiling on stable relationships a person can track at once, so it describes a functional community and says nothing about close friendship.
The inner layers do different jobs. Your support clique carries you through hard times with practical and emotional help, and the sympathy group is the scaffolding of an ordinary social life, so losing someone from either hurts wellbeing far more than losing an outer contact. The inner monologue calculator looks at another private experience that varies more between people than most of us assume.
The friendship recession: why people have fewer friends today
The Survey Center on American Life's 2021 report gave the name friendship recession to what has happened among American adults, and among men in particular. In 1990, 55% of men said they had six or more close friends. By 2021 that was 27%, so close male friendship halved in 30 years, and women's counts fell too, though by less. Bear in mind that this comparison comes from a different survey than the Pew figures above, so the two sets of numbers sit side by side rather than on one scale.
Nobody agrees on the causes. Structural explanations point at suburban living, longer commutes that remove incidental contact, and the fading of the churches, unions, clubs and societies that once gave working adults a regular reason to gather with the same people. Individual explanations point at the growing expectation that a partner should supply every kind of emotional support, which leaves less room for close friends of the same sex.
Technology cuts both ways. Social media can hand you the feeling of connection while the real thing thins out, keeping hundreds of weak ties alive as the deeper friendships starve for lack of time in the same room. The pandemic then sped everything up, and the 2021 data was gathered as people came out of two years of restricted contact with many close friendships weakened or gone.
Why do friendship networks shrink with age?
Networks shrink with age partly by choice, because socioemotional selectivity theory, developed by Laura Carstensen, shows that when people sense less time ahead of them they stop gathering information through large, varied networks and start protecting emotional quality through a few close relationships, letting the peripheral contacts lapse without much distress. Older adults hold their closest people tighter and let the rest go.
The convoy model from Kahn and Antonucci pictures your supporters as a convoy travelling with you through life. Every role change reshuffles it, whether marriage, parenthood, a new career, retirement or bereavement, and each shuffle tends to shrink the whole while sometimes deepening the core. Having children shows up as a measurable drop in close friend count, because the hours have to come from somewhere.
Then there's plain logistics. A close friendship needs repeated contact, ideally face to face, and moving cities and long hours eat the time that takes, and so do family commitments. Friendships made in structured settings such as school, an early job or shared housing survive more easily than ones that need diaries to be compared, which is why the move from education into working life is where so many people lose friends without noticing.
Frequently asked questions
More common than most people assume. Pew Research Center data from 2023 puts it at roughly 8% of US adults. That doesn't make it harmless, since a large body of research ties social isolation to higher all-cause mortality and to more cardiovascular disease and depression. But about one adult in twelve is in the same position, and it's something people do change in adulthood with deliberate effort.
Between 1 and 4, for most American adults. Around 50% of men and 55% of women told Pew Research in 2023 (n=5,057) they had that many, with the share reporting 5 or more rising from 32% under 30 to 49% at 65 and over. Dunbar's model puts the support clique at about 5 people, so 3 or 4 sits squarely in the normal range at any age. Some 8% report none.
Men's friendships tend to be built around doing things together, sport or work, while women's tend to be built around talking, and that difference decides what survives. When the shared activity stops, with a job change, say, the men's friendship often fades with it, whereas a friendship built on disclosure can be kept up across distance and long gaps. Men are also less likely to reach out when they're struggling, so friends drift exactly when support is needed.
Yes, though it takes more hours than most people budget. Hall at the University of Kansas found it takes about 50 hours to go from acquaintance to casual friend, 90 to become a friend, and over 200 to become a close friend. Adult life has fewer spare hours, so what works is repeated low-stakes contact in a shared setting, a class or a club, with disclosure building gradually. Scheduling the time rather than waiting for it is the difference.
About 150, meaning the number of stable relationships a person can track at once, not 150 close friends. Dunbar's 1992 paper in the Journal of Human Evolution derived it from the size of the human neocortex relative to the brain. In Dunbar's 2018 review in Trends in Cognitive Sciences, 150 sits outside nested layers of about 5, 15 and 50; the support clique of about 5 and the sympathy group of about 15 are the ones that matter for wellbeing. Treat 150 as a community's ceiling, not a target.
Loneliness is the feeling that your need for connection isn't met, so you can be lonely with a hundred acquaintances and content with two close friends. The US Surgeon General's 2023 advisory cited surveys finding that about half of American adults report experiencing loneliness. That sits alongside every possible friend count. What predicts loneliness in the research is relationship quality, specifically whether you believe support would be there if you needed it. Loneliness by age is set out in our mental health statistics.
Quality. Holt-Lunstad, Smith and Layton's 2010 review of 148 studies found that detailed measures of how woven into other people's lives someone was predicted survival far more strongly than a bare fact such as living alone. The Harvard Study of Adult Development, with 80+ years of follow-up, found the quality of close relationships at midlife predicted health and happiness at 80 better than cholesterol, exercise or career success. One good close relationship is enough to protect against isolation.
Both cost friends. Marriage merges two social lives into one and squeezes friendships outside it. Parenthood costs more, and the Survey Center on American Life (2021) notes that American parents spend about twice as much time with their children as earlier generations did, which crowds out friendships. Time is the mechanism. The friendships that survive are with other parents on similar schedules, or ones deep enough that occasional contact keeps them alive. Our relationship statistics roundup covers the marriage and family side of those same years.
They help more as a support for friendships than as a substitute. Mitev et al. (2021, Technology, Mind, and Behavior) compared days when adults in the UK and Bulgaria used social media less than usual with days of normal or heavy use. Wellbeing didn't change, but the UK group felt less socially connected on the low-use days, so the messaging seems to keep existing ties going. Nothing in that work shows online contact building a close friendship on its own.
It sped up a decline already under way and added losses. The Survey Center on American Life's May 2021 survey found 47% of Americans had lost touch with at least a few friends over the previous year, and 9% with most of them. It also put the share with no close friends at 12%, against 3% in a 1990 Gallup survey, though the two polls used different methods.
Holt-Lunstad, Smith and Layton's 2010 meta-analysis in PLoS Medicine (148 studies, 308,849 participants) found adequate social relationships came with a 50% higher likelihood of survival than poor ones, controlling for age, sex and baseline health. That puts it on a par with smoking and alcohol consumption as a mortality risk, and ahead of obesity and physical inactivity. Isolation raises cortisol and inflammatory markers such as IL-6 and CRP, disturbs sleep and weakens immunity, which is why the US Surgeon General's 2023 advisory called it a public health crisis.
Starting with what counts as a friend. In much of East Asia, particularly China, Japan and South Korea, friendship is a smaller, more exclusive category than in North America or Northern Europe, but carries heavier obligations. Adams and Plaut (2003, Personal Relationships) found Ghanaian adults defined friendship more narrowly and gave it more practical support duties than Americans. Mediterranean and Latin American networks run larger and blur into extended family. Cross-cultural counts partly measure definitions, not depth.
