# State of Longevity Cities 2026

The year in numbers across the Longevity Cities network: how many cities met, how often, what the library graded, and what the community finished together.

Counted from 1 January 2026 to 18 September 2026.

## 01 39 cities in 16 countries met this year

Cities on 3 continents, 15,620 kilometres between Miami and Bangkok at the widest.

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.

## 03 4,914 places are on the map

1862 of them are Sauna, spa and recovery.

## 05 271 papers were graded, 39 of them strong

59 of the 98 questions on the evidence map still have no paper behind them.

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.

| Grade | Papers | Share |

## 06 27 articles were written and 18 newsletters went out

brain health was the topic that came back most often: 8 of the 18 issues carried it.

Counted from articles published inside the period. Guides are not counted: the guide hub is static, with no publication date to place an entry in a year. The rows show what each newsletter issue was made of.

## 07 Face age was the tool people reached for most

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.

1. Face age
2. Pace of aging
3. Grip strength
4. HOMA-IR
5. VO2max estimate
6. Pseudoscience checker
7. Calorie calculator
8. Protein calculator
9. Jet lag planner
10. Menopause test
11. Zone 2 calculator

## 08 899 people joined, taking the membership from 12 to 911

223 of the 327 members who said why came for Events and community.

Counted from member accounts by the date each account was created, with 12 accounts already in place when the year began. An account that was deleted is gone from the collection, so this counts the accounts that still exist rather than every sign-up ever made.

## 09 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.

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.

## 10 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.

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.
