Online Communities in America: What Pew Found About Belonging Online

Nearly four in ten adults now belong to online communities in America, and among younger adults it’s close to half. That’s the headline from Pew Research Center’s Online Community and Connection in America, released 14 October 2026 from a survey of 9,750 U.S. adults conducted 26 May to 1 June 2026 (Pew Research Center). Information verified through 23 October 2026.

The topline figure is 36% of U.S. adults. It climbs with youth and falls with age: 48% of 18- to 29-year-olds, 40% of those 30 to 49, 32% of those 50 to 64, and 26% of adults 65 and older say they’re part of an online community, per the report. Music Ally’s summary of the same release lands on identical numbers (Music Ally).

These aren’t one-off visits. Among members, 85% belong to more than one community, 56% visit their most-visited one every day, and 74% say they post or share there, according to Pew. One in five U.S. adults overall is in an online community daily. That rhythm — daily, habitual, woven into ordinary life — is what makes the findings worth reading slowly.

Virtual third places online: hobbies first, politics last

Pew asked what these spaces are about, and the answer looks strikingly ordinary. Hobbies lead at 23% of adults, followed by local-area communities at 21%. Movies, books or TV shows drew 13%. Work or profession, video games and fan communities each drew 12%, per the report — a breakdown Music Ally also highlighted for the fan figure (Music Ally). Social media is the most common venue, at about a quarter of adults, with discussion forums such as Reddit, Nextdoor or Discord next at 15%.

Sociologists have a name for places like this — third places, neither home nor work, where people gather without a formal purpose. Pew’s earlier work used “virtual third places” for the online version, and this survey reads like a census of them. About six in ten members — 63% — say their most-visited community offers something they could only find online, per the report. Roughly seven in ten say these spaces add something to their lives, including about a quarter who say they add deeply. Twenty-nine percent, though, say their communities bring little to no value. Both things are true at once, often for the same person across different groups.

People show up mainly to stay informed, for fun, or for advice and recommendations — eight in ten or more cite each as a reason, Pew found. Feeling accepted matters to just over half. Meeting new people ranks low. And closeness is patchy: about one in five members feels extremely or very close to others in their go-to community, while nearly half don’t feel very close at all. Most — 68% — knew few or none of the other members before joining.

Politics, notably, is a guest rather than a resident. Only 8% of adults are in a community specifically about politics, and 71% of members say little to none of the discussion in their most-visited community is political, per Pew. A 54% majority say politics doesn’t belong in that space at all.

Are online relationships as meaningful as in-person ones? America splits by age

Here’s the fault line. Asked whether online relationships can be as meaningful as in-person ones, 47% of adults say they are not as meaningful, 34% say they can be just as meaningful, and 20% aren’t sure, according to the report. Age rewrites the answer. Among 18- to 29-year-olds, 54% say online relationships can be just as meaningful — the only age group where that view wins — while just 14% of adults 65 and older agree.

Membership itself shifts the judgment. Among people who are in an online community, 48% say online relationships can match in-person ones, compared with a quarter of those who aren’t in one, per Pew. On the wider question, 58% say the internet both brings people together and drives them apart about equally; 31% say it divides more, 11% that it connects more. Young adults, Pew notes, are also more likely to go to their communities to feel accepted or meet people — and, the report adds dryly, for the drama.

Why people leave online communities

Belonging online is often temporary. About a third of U.S. adults say they have left an online community at some point, per Pew. Wisevoter’s summary of the survey puts the figure at 32% and reports the reasons leavers gave: 80% cited declining interest, 57% pointed to arguing, and 43% cited harassment, with 40% naming too much politics and 37% the time participation took (Wisevoter). Pew’s own framing agrees on the top cause: losing interest is the most common reason people leave.

That pattern — join for a hobby, drift as interest fades, quit if arguing takes over — looks less like a crisis of the internet and more like how voluntary groups have always behaved, in church halls and club rooms long before forums existed.

Analysis: Read together, the numbers describe infrastructure, not escape. For a third of the country, and half of its young adults, an online group is simply one of the places community happens now — prized for the niche thing it alone provides, kept at arm’s length by many who use it daily, and abandoned without ceremony when it stops earning its place. The argument about whether it “counts” is increasingly generational, and generations age.
