39 cities in 16 countries met this year
Cities on 3 continents, 15,620 kilometres between Miami and Bangkok at the widest.
Where the cities areA dotted world map with one mark per city. Hamburg sits furthest north and Bangkok furthest south, and those two are the only marks in red. Cities founded during this period carry a light grey ring.
Counted from city pages that were live at the end of the period. A city founded during the period carries a light ring; the only red marks on the map are the two cities at its edges.Counted from 1 January 2026 to 18 September 2026.

What kind of meetup it wasOne bar per format, longest first. The most common recorded format is marked in red.
Counted from the same 143 meetups, of which 129 record a format at all. The bars are shares of those. A meetup that never recorded a format lands in its own bucket rather than being guessed into one; a retired format name is folded into the format that replaced it.Counted from 1 January 2026 to 18 September 2026.

271 papers were graded, 39 of them strong
59 of the 98 questions on the evidence map still have no paper behind them.
How strong the evidence wasThree bars, one per grade, showing how many papers carry it and what share of the graded papers that is.
Counted from papers added to the library inside the period, each with a grade a human signed off. Each bar also carries its share of the graded papers. No paper age is shown: the library takes in the year's papers, so every one of them is from this year.Counted from 1 January 2026 to 18 September 2026.

What the papers were aboutSix bars, one per intervention the evidence map asks about, showing how many of the year's papers speak to it.
Of the fourteen interventions the evidence map asks about. 144 of 271 graded papers name one at all; the rest are about something else we read. A paper about two levers is counted under both. Read through the same tag and MeSH tables the map uses, so nothing is guessed, and MeSH is thin on papers an editor added by hand.Counted from 1 January 2026 to 18 September 2026.

What kind of studies they wereFour bars showing how the year's papers split across trial, synthesis, review and everything else.
Of the 227 of 271 graded papers that carry a PubMed publication type; a paper an editor added by hand has none, so it is outside this figure rather than counted as something else. PubMed puts several types on one paper, so each paper lands in the first bucket that fits, trials before syntheses before reviews. A trial protocol is a plan, not a trial, and counts as everything else.Counted from 1 January 2026 to 18 September 2026.

What else the year's reading showsA short list: open questions on the evidence map, pre-registered trials, papers free to read, and how many grades carry a written reason.
Each row states its own denominator, because almost none of them is a share of all 271 graded papers. The day a paper enters the library is the day we read it, not the day it was published, and an editor can change it. Retraction notices are only seen on papers that came in this year.Counted from 1 January 2026 to 18 September 2026.

How much of it a German reader gets in GermanTwo shares: the year's articles with a German body, and the year's papers with a German title and summary.
A paper counts as translated only when both its title and its summary carry German; an article counts when its body exists in German. Both are of the year's own output, not of the whole library.Counted from 1 January 2026 to 18 September 2026.

Face age was the tool people reached for most
Which tool people reached forThe tools in order, the one people opened most at the top. No counts: the order is the finding.
Ranked by how often each tool page was opened, both language pages of a tool folded together, bots left out. Sub-pages of a tool are content rather than the tool, so they do not count. The counts themselves are deliberately not published: the order is the finding, the traffic behind it is ours. Nothing here is tied back to a person.Counted from 1 January 2026 to 18 September 2026.

The Longevity Check in the roomThree numbers: checks finished, sessions they were finished at, and cities.
Counted from finished checks inside the period. Participation only: how many people did it, where, and at which station. No score, no percentile, no age and no gender is published. A result carries no consent to publish what it measured, so nothing that measures a body leaves the database. A station fewer than 20 people attempted is not named.Counted from 1 January 2026 to 18 September 2026.

Why they joinedOne bar per reason people picked when they signed up, ranked.
Of 327 members who answered the question at all, out of 899 who joined this year. One member can pick several reasons, so the bars add up to more than the people behind them. Counted from the goals people chose, not from the interests those goals switch on.Of 899 members who joined this year. Dating is only published from 10 members up, so a smaller figure shows a dash.Counted from 1 January 2026 to 18 September 2026.

17 habit partnerships were put up, alongside 2 pods and 85 partner check-ins
10 of the 17 found a partner, 9 of them got going, and 301 badges were earned along the way.
How far the pods gotFour bars: how many pods formed, how many reached their quorum, how many confirmed a start, and how many ended early.
Counted from habit partnerships and accountability pods by the date each step happened: put up, matched, started, finished. A pod still waiting for people to join has no start date at all, so forming is what anchors it. Check-ins count by the day they were logged.Counted from 1 January 2026 to 18 September 2026.

Vitamin D3 was the most-stacked item, in 49% of the 318 stacks people share
Supplements is the biggest group, named by 268 of 318 members. 2,001 entries were added this year.
How many stacks the chapter readsTwo numbers: members sharing a stack, and the entries in those stacks.
Counted in distinct members, never in entries: an item a member listed twice is still one member. Members who switched their stack off, and members whose profile is private, are left out of every figure here. Nothing is shown below 20 members, and an item under that is not named at all. There is no split by city, by age or by gender anywhere in this chapter. All of it is self-reported.Counted from 1 January 2026 to 18 September 2026.
