How old are Redditors, and which subreddits does each age stand out in?

Every age has a subreddit where it stands out

For each age group we looked for the subreddit where that age makes up an unusually large share of the people posting, compared with Reddit as a whole. Take r/osrs: of its male authors with a known age, 46.8% were 28 to 32 when they wrote there, against 16.7% of male authors across Reddit. That is 2.8 times the usual share, and r/osrs ranks first for men that age. We did the same for women and men separately, for every five-year age group from 13 to 75.

From their late twenties to their late fifties, women's most over-represented subreddits follow fertility, babies and menopause. At 28 to 32 it is r/TFABChartStalkers (cycle charts, trying to conceive), at 33 to 37 r/SnooLife (SNOO smart baby bassinet), then r/Perimenopause from 38 to 47 and r/Menopause from 48 to 57. In r/Menopause, 25.4% of the women with a known age were 48 to 52, 8.5 times their share of Reddit.

Men's follow what they played, watched and listened to growing up: r/osrs (Old School RuneScape) at 28 to 32, r/Diablo_2_Resurrected (Diablo II remaster) at 33 to 37, r/RetroNickelodeon (pre-SpongeBob Nickelodeon) at 38 to 42, r/Robocop at 43 to 47 and r/hairmetal ('80s glam metal) from 48 to 57. Parenting does show up for men, just lower down: r/NewParents is third at 33 to 37.

From 58 on, both columns arrive at the same place, r/retirement: it leads for men from 58 to 75 and for women from 58 to 67, with r/ClassicTV on top for women at 68 to 75. The youngest groups are mostly kids' games and YouTubers (r/GachaClub, r/DaniDev). In the early twenties the leaders include Indian exam, college and city subreddits (r/Neet_india, r/delhiuniversity, r/bangalorerentals), along with r/Frat for men at 18 to 22 and r/SevenWordStories (breakups in seven words) for women at 23 to 27.

A quick check that the ages are right: subreddits named after an age, which we left out of the chart, win their own groups. r/over60 would lead at 63 to 67 with 25.2 times the usual share, and r/GenX at 48 to 52.

How old are Redditors?

Among authors active in the first nine months of 2026 who have mentioned their age, the median was 27. 70% were between 18 and 34: 33.1% were 18 to 24 and 36.5% were 25 to 34. 17.1% were 35 to 44, and 9.8% were 45 or older. 3.5% were under 18.

Reddit's authors have been getting older. In 2019 the median author with a known age was 24, and 16.0% were under 18. By 2026 the median was 27 and the under-18 share had fallen to 3.5%. Authors aged 40 and over went the other way, from 9.8% to 16.3%, and have outnumbered under-18s since 2022.

What's the gender ratio on Reddit?

Among authors active in 2026 who have mentioned their gender, 39.9% were women. In 2019 it was 31.2%. The share went up every year in our data, and it is highest among 18 to 24-year-olds: 47.7% of authors that age with a known gender were women in 2026, against 34.7% of those aged 45 to 54.

Subreddit by subreddit, the split ranges from almost all women to almost all men. Among the 735 largest English-language subreddits (by authors with a known gender), r/pregnant is 93% women and r/fantasyfootball is 7%. Only 88 of the 735 have more women than men, and the median subreddit is 25% women.

Who this data covers

• Only people who said it. Everyone here wrote something like "I'm 34", "(29F)" or "as a woman" in a public post or comment. Of the 75.1 million accounts that posted or commented in 2025, 13.0% have a known age and 20.1% a known gender. People who mention their age or gender may differ from people who don't, and some subreddits ask for it in post titles.
• Over-represented doesn't mean biggest. The chart shows where an age group stands out, not where most of it posts. A subreddit can lead for 30-year-old men while most 30-year-old men never visit it.
• Accounts, not people. Someone with two accounts counts twice, and accounts that were deleted are left out. Known bots are left out too.
• Ages come from statements, and statements can be jokes. We take the middle of all of a person's statements, which keeps one joke from moving it, and drop people whose statements point to too many different birth years.
• Reddit changed how author IDs look in July 2018, so in our archive the same person has one ID before and another after. The yearly numbers start in 2019 for that reason; the subreddit numbers cover 2016 to 2026, where some people may count twice.
• Gender here is men and women. People who describe themselves otherwise, or whose statements disagree, are not in the gender numbers.

Method

Age and gender

We read every public post and comment in our archive for statements about the writer's own age and gender: phrases like "I'm 34", "34F", "as a woman" or "my wife and I". Each statement about age gives a birth year (the year it was written minus the age stated), and a person's birth year is the middle of all of theirs. Gender comes from direct statements first; weaker clues are only used when there are none. Patterns that turned out to be mostly about something else are left out: game levels, "born in" statements about generations, and model codes like "F56" in car and gear subreddits that look like "female, 56".

Age at the time of writing

A person's age in a subreddit is their age in the middle month of their activity there, so someone who posted in r/teenagers at 15 counts as 15 there even if they are 25 now. In the yearly numbers, age is the calendar year minus the birth year.

Over-representation

For each subreddit and five-year age group (13 to 17, 18 to 22, and so on up to 68 to 75), we take the share of the subreddit's authors with a known age who were in that group, and divide it by the group's share across all subreddits. Women and men are counted separately. To keep small subreddits from winning on chance, we rank by the lower end of the 95% confidence interval of the share. Candidates are English-language, non-NSFW subreddits in the top 10% by authors with a known age (7,193 subreddits for women, 7,212 for men). Subreddits with an age, a decade or a generation in their name (r/over60, r/GenX, r/90s_kid) are left out, because they win their own groups by definition; so are names with slurs.
