Sedentary lifestyle statistics describe several related but different measures: insufficient physical activity, sitting and screen-time proxies, time-use patterns, and modeled health burdens. The figures below make the population, geography, period, and measurement type explicit so these measures are not treated as interchangeable.
Key Sedentary Lifestyle Statistics
The following highlights span global activity levels, age-specific guidance, U.S. time use, adolescent screen exposure, and measured or modeled outcomes:
- In 2022, 31% of adults worldwide did not meet recommended physical-activity levels, an estimate covering approximately 1.8 billion people.
- Between 2010 and 2022, global adult physical inactivity increased by about 5 percentage points.
- If the observed trend continues, 35% of adults worldwide are projected not to meet activity recommendations in 2030.
- In 2022, adult physical inactivity was 48% in high-income Asia Pacific, compared with 28% in high-income Western countries.
- In 2022, women had a 34% global adult physical-inactivity rate, compared with 29% for men.
- In 2022, 32 countries had adult physical-inactivity levels above 40%, including 10 above 50%.
- WHO’s 2019 guidance says 2-year-olds should have no more than 1 hour of sedentary screen time per day.
- In 2025, U.S. people aged 15 and over spent 2.61 hours per day watching TV, based on annual time-use averages.
- In 2025, U.S. people aged 15 and over spent 3.32 hours per day in working and work-related activities.
- In 2025, 95% of Americans aged 15 and over engaged in some leisure or sports activity on an average day.
- In 2025, U.S. adults aged 75 and over spent 7.39 hours per day in leisure and sports activities.
- During July 2021–December 2023, 50.4% of U.S. teenagers aged 12–17 reported at least 4 hours of daily screen time.
- During July 2021–December 2023, 55.0% of U.S. teenagers aged 15–17 reported at least 4 hours of daily screen time, compared with 45.6% of those aged 12–14.
- During July 2021–December 2023, 52.5% of U.S. girls aged 12–17 reported at least 4 hours of daily screen time, compared with 48.3% of boys.
- Among U.S. teenagers aged 12–17 during July 2021–December 2023, 27.1% of those with at least 4 hours of daily screen time had anxiety symptoms in the previous 2 weeks, versus 12.3% among those with less than 4 hours.
- WHO states that insufficiently active people have a 20%–30% higher risk of death than sufficiently active people.
- If physical inactivity prevalence did not change, almost 500 million new preventable noncommunicable-disease cases were projected for 2020–2030.
- The projected treatment cost of those inactivity-attributable cases was about US$27 billion per year during the 2020–2030 forecast period.

Global Sedentary Lifestyle Trends and Physical Inactivity
The strongest global measure in this dataset is insufficient physical activity, which is related to sedentary living but does not directly measure sitting time. WHO and Lancet pooled estimates put adult inactivity at 31% worldwide in 2022, or approximately 1.8 billion adults.
The same estimate shows a worsening trend: adult physical inactivity increased by about 5 percentage points between 2010 and 2022. If that trend continues, the estimate reaches 35% in 2030, which is a projection rather than an observed result. WHO, “Nearly 1.8 billion adults at risk of disease from not doing enough physical activity”
Regional estimates show substantial variation:
| Region or group | Adult physical inactivity | Period and measure |
|---|---|---|
| High-income Asia Pacific | 48% | 2022 estimate |
| South Asia | 45% | 2022 estimate |
| High-income Western countries | 28% | 2022 estimate |
| Oceania | 14% | 2022 estimate |
The global adult rate was 34% for women and 29% for men in 2022. In the same year, 32 countries had adult inactivity levels above 40%, and 10 countries were above 50%.
These figures measure failure to meet activity recommendations, not total daily sitting time. WHO, “Nearly 1.8 billion adults at risk of disease from not doing enough physical activity” WHO, “Global levels of physical inactivity in adults: 2022 estimates”
Age-Specific Sedentary-Time Benchmarks
WHO’s 2019 guidance provides age-specific benchmarks rather than observed population averages. It combines limits on restraint or sedentary screen time with minimum activity and sleep recommendations.
| Age group | Sedentary or activity benchmark | Sleep benchmark |
|---|---|---|
| Non-mobile infants under 1 | At least 30 minutes of prone-position tummy time spread across the day; no restraint for more than 1 hour at a time | 14–17 hours for ages 0–3 months; 12–16 hours for ages 4–11 months |
| Children aged 1–2 | At least 180 minutes of physical activity across the day | Not specified in the supplied benchmark |
| Children aged 2 | No more than 1 hour of sedentary screen time per day | Not specified in the supplied benchmark |
| Children aged 3–4 | At least 180 minutes of activity, including at least 60 minutes moderate-to-vigorous | 10–13 hours per 24 hours |
The guidance is useful for interpreting sedentary behavior, but it should not be read as evidence that a population actually meets or misses each benchmark. WHO, “To grow up healthy, children need to sit less and play more”
U.S. Time-Use Data Linked to Sedentary Living
The American Time Use Survey provides diary-based proxies for activities commonly associated with sedentary living. Its categories are not identical to total sitting time, and work, education, leisure, and screen use should not be added together as a single sitting estimate.
For the U.S. civilian population aged 15 and over, 2025 annual averages show 5.16 hours per day in leisure and sports activities. Within related categories, people spent 2.61 hours watching TV, 0.62 hours playing games or using a computer for leisure, and 0.34 hours in sports, exercise, and recreation each day.
Working and work-related activities accounted for 3.32 hours per day, including 3.03 hours working. Educational activities accounted for 0.44 hours per day.
In addition, 95% of Americans aged 15 and over engaged in some leisure or sports activity on an average day in 2025. BLS, “American Time Use Survey Summary – 2025 A01 Results” BLS, “Table 1. Time spent in primary activities and percent of the civilian population engaging in each activity, averages per day by sex, 2025 annual averages”
TV time also differed by sex: men aged 15 and over averaged 2.81 hours per day watching TV, compared with 2.42 hours for women in 2025. These are annual survey averages, not direct accelerometer measurements of sitting. BLS, “Table 1. Time spent in primary activities and percent of the civilian population engaging in each activity, averages per day by sex, 2025 annual averages”
Sedentary Behavior by U.S. Age and Employment Group
U.S. 2025 time-use data show that leisure and sports time varies considerably across age and employment groups. Because the category is broader than sedentary behavior, the figures indicate daily time allocation rather than a direct sitting total.
| U.S. group | Leisure and sports | TV viewing |
|---|---|---|
| Teenagers aged 15–19 | 5.66 hours/day | Not supplied |
| Adults aged 35–44 | 3.89 hours/day | Not supplied |
| Adults aged 65–74 | Not supplied | 4.20 hours/day |
| Adults aged 75+ | 7.39 hours/day | 4.43 hours/day |
| Employed people aged 15+ | 4.17 hours/day | Not supplied |
| Full-time workers | 3.99 hours/day | Not supplied |
| Not-employed people aged 15+ | 6.66 hours/day | Not supplied |
The age pattern is not a simple linear measure of sedentary time: older adults aged 75 and over recorded the highest leisure-and-sports average in the supplied groups, while adults aged 35–44 recorded a lower average. The BLS category includes activities beyond sitting, so these observations should not be labeled as measured sedentary minutes. BLS, “Table 3. Time spent in primary activities for the civilian population by age, sex, race, Hispanic or Latino ethnicity, marital status, and educational attainment, 2025 annual averages” BLS, “Table 11A. Time spent in leisure and sports activities for the civilian population by selected characteristics, averages per day, 2025 annual averages”
Adolescent Screen-Time Statistics in the United States
CDC data provide a more focused sedentary proxy for adolescents: self-reported typical weekday screen time excluding schoolwork. During July 2021–December 2023, 50.4% of U.S. teenagers aged 12–17 reported 4 or more hours per day.
The distribution was 22.8% reporting 3 hours, 17.8% reporting 2 hours, 6.1% reporting 1 hour, and 3.0% reporting less than 1 hour. These categories describe screen exposure and are not equivalent to all sedentary behavior.
Differences appeared across demographic and place-based groups:
- Among teenagers aged 15–17, 55.0% reported at least 4 hours of daily screen time, compared with 45.6% among those aged 12–14.
- Among boys aged 12–17, 48.3% reported at least 4 hours of daily screen time, compared with 52.5% among girls.
- Among Black non-Hispanic teenagers aged 12–17, 60.4% reported at least 4 hours of daily screen time.
- Among teenagers whose highest parental education was a college degree or higher, 45.2% reported at least 4 hours of daily screen time.
- Among metropolitan teenagers aged 12–17, 51.4% reported at least 4 hours of daily screen time, compared with 43.3% in nonmetropolitan areas.
The CDC figures are self-reported and cover a typical weekday during July 2021–December 2023. They exclude schoolwork, so they should not be interpreted as a complete daily sitting or screen-time total. CDC, “NCHS Data Brief, Number 513: Daily Screen Time Among Teenagers: United States, July 2021–December 2023”
Sedentary Lifestyle Outcomes, Costs, and Policy Burden
Health outcome figures in this dataset primarily concern insufficient physical activity or associations with adolescent screen time. WHO states that insufficiently active people have a 20%–30% higher risk of death than sufficiently active people, but this is not a direct estimate of risk from sitting alone. WHO, “Physical activity”
Among U.S. teenagers aged 12–17 during July 2021–December 2023, 27.1% of those reporting at least 4 hours of daily screen time had anxiety symptoms in the previous 2 weeks, compared with 12.3% among those reporting less than 4 hours. Depression symptoms were reported by 25.9% of the 4-or-more-hour group and 9.5% of the less-than-4-hour group.
These are cross-sectional associations, not evidence that screen time caused the symptoms. CDC, “NCHS Data Brief, Number 513: Daily Screen Time Among Teenagers: United States, July 2021–December 2023”
WHO modeled the wider burden of physical inactivity for 2020–2030 under a scenario in which prevalence did not change. The model projected almost 500 million new preventable noncommunicable-disease cases, with treatment costs of about US$27 billion per year and approximately US$300 billion in health-system costs over the period.
These are forecasts and modeled estimates about physical inactivity, not direct costs attributable to sitting alone. WHO, “WHO highlights high cost of physical inactivity in first-ever global report”
The policy environment was also measured. The 2022 WHO assessment covered 194 countries, and fewer than 50% had a national physical-activity policy at that time. WHO, “WHO highlights high cost of physical inactivity in first-ever global report”
