Three in ten adults worldwide don’t move enough. The World Health Organization (WHO) physical activity fact sheet (26 June 2024) says 31%, about 1.8 billion adults miss the recommended level, a rise of 5 percentage points from 2010 to 2022, heading for 35% by 2030. Insufficiently active people have a 20–30% higher risk of death. The figures and age-group benefits are set out below.
1. 31% of adults (about 1.8 billion) miss the guidelines, projected 35% by 2030.
2. Inactivity: 20–30% higher risk of death.
3. Adults: 150 minutes of moderate activity a week — any activity beats none.
Key figures — WHO
| Item | WHO figure | Worth noting (ours) |
|---|---|---|
| Adults below the guidelines | 31%, about 1.8 billion | — |
| Trend | Up 5 points 2010–2022; 35% projected for 2030 | — |
| Adolescents (11–17) | Key facts 80%, body text 81% | The page differs by 1 point |
| Sex | Girls 85%, boys 78%; women average 5 points less active than men | — |
| Death risk | 20–30% higher if insufficiently active | — |
| Cost | About US$300 billion 2020–2030 (about US$27 billion a year) | 300 ÷ 11 ≈ 27.3 (our arithmetic) |
| Targets | 10% relative reduction by 2025, 15% by 2030, from 2010 | — |
Reading the numbers — our notes
31% is roughly 3 adults in 10. If 1.8 billion is 31%, the adult population counted is about 5.8 billion (1.8 ÷ 0.31 ≈ 5.8, our arithmetic). The 20–30% higher death risk is relative to sufficiently active people, not an individual’s absolute risk (our note). Against targets of a 10–15% relative reduction from 2010, the trend actually rose 5 points — the contrast this fact sheet shows.
Who gains what — WHO
| Type | What the source says | Worth noting (ours) |
|---|---|---|
| Children, adolescents | Fitness, cardiometabolic and bone health, cognitive and mental health, less body fat | — |
| Adults, older adults | Lower all-cause and cardiovascular mortality, hypertension, some cancers, type 2 diabetes and falls; better mental health, cognition and sleep | — |
| Pregnancy, postpartum | Lower risk of pre-eclampsia, gestational hypertension and diabetes, excess weight gain, delivery complications, postpartum depression. No harm to birthweight or added stillbirth risk | — |
| Everyone | Any activity beats none, all activity counts, limit sitting, and strength work benefits everyone | — |
The WHO recommends 150 minutes+ moderate a week for adults and puts other groups in separate guidelines. The UK view is in adult activity guidelines; children in children’s activity; sitting in sitting time.
In daily life — our reading
“All activity counts” means commuting on foot, stairs and housework add to the 150 minutes even without set workouts. About 22 minutes of walking a day passes 150 a week (22 × 7 = 154, our arithmetic). Strength work “benefits everyone” on top of aerobic activity, so bodyweight exercise twice a week is the next step.
Checklist
- ☐ Do I reach 150 moderate minutes a week?
- ☐ Strength work too?
- ☐ Less sitting?
- ☐ Children: use the WHO child guidelines
- ☐ Some beats none
Questions that remain
What about Korea?
The fact sheet gives global figures only; country data is elsewhere on WHO’s site and we didn’t open it.
Why two adolescent figures?
The key facts say 80% and the body 81%; the page doesn’t explain, so we’ve given both.
