Back pain is a major source of disability across populations, but estimates depend on the definition, recall period, age group, and whether the figure comes from a survey or a modeled burden study. The figures below distinguish those measures and identify their geography and period.
Key Back Pain Statistics
The most broadly useful figures are:
- In 2020, an estimated 619 million people worldwide had low back pain.
- By 2050, global low back pain cases are forecast to reach 843 million, driven largely by population growth and ageing.
- From 1990 to 2020, the modeled global number of low back pain cases increased 60%.
- In 2020, low back pain accounted for 8.1% of all-cause years lived with disability globally.
- In the WHO summary accessed in 2026, about 90% of low back pain cases were estimated to be non-specific.
- In 2019, 39.0% of U.S. adults aged 18 and older reported back pain in the previous 3 months.
- In 2019, 45.6% of U.S. adults aged 65 and older reported back pain in the previous 3 months.
- In 2019, 40.6% of U.S. women aged 18 and older reported back pain in the previous 3 months.
- In 2019, 44.8% of U.S. adults below 100% of the federal poverty level reported back pain in the previous 3 months.
- In 2015, 26.4% of U.S. workers reported any low back pain.
- In 2015, 5.6% of U.S. workers reported low back pain attributed to work by a health professional.
- In 2021, an estimated 271,680,057 adults aged 55 and older worldwide had low back pain.
- In 2021, the global age-standardized prevalence rate among adults aged 55 and older was 18,282.8 per 100,000.
- In 2021, low back pain caused an estimated 29,470,959 years lived with disability among global adults aged 55 and older.
- From 1990 to 2021, the global age-standardized prevalence rate among adults aged 55 and older fell 10.4%, even though absolute case counts can still rise.
- In 2021, Central Europe had an age-standardized prevalence rate of 29,992.8 per 100,000 among adults aged 55 and older.
- In 2021, Hungary had the highest national age-standardized prevalence rate among adults aged 55 and older, at 32,592.8 per 100,000.

Global Prevalence, Definitions, and Projected Growth
The World Health Organization defines low back pain as pain between the lower ribs and the gluteal folds lasting at least one day in the underlying Global Burden of Disease analysis. The WHO summary accessed in 2026 also describes acute low back pain as lasting less than 6 weeks, subacute pain as 6–12 weeks, and chronic pain as 12 weeks or longer.
According to the World Health Organization’s “Low back pain” fact sheet, the global scale and age pattern include:
- An estimated 619 million people worldwide had low back pain in 2020.
- Low back pain prevalence increases with age up to 80 years.
- The highest number of modeled cases occurs at ages 50–55 years; this is the largest case count by age band, not necessarily the highest age-specific rate.
- About 90% of low back pain cases are non-specific rather than attributable to an identifiable disease or structural problem, although the WHO describes this as approximate and definitions can vary by care setting.
The WHO release on guidelines for chronic low back pain reports that the 2020 global case count was 60% higher than the modeled 1990 estimate. It also states that low back pain represented 8.1% of all-cause years lived with disability globally in 2020.
The same WHO source reports a forecast of 843 million cases by 2050. This is a modeled projection driven largely by population growth and ageing, not an observed count or a guarantee about future prevalence.
U.S. Adult Back Pain Data and Demographic Differences
The National Center for Health Statistics report “Back, Lower Limb, and Upper Limb Pain Among U.S. Adults, 2019” uses the National Health Interview Survey. Its back-pain measure asked whether civilian, noninstitutionalized adults had been bothered by back pain during the previous 3 months, ranging from a little to a lot.
In 2019, 39.0% of U.S. adults aged 18 and older reported back pain. The age pattern was:
| U.S. population, 2019 | Adults reporting back pain in past 3 months |
|---|---|
| Ages 18–29 | 28.4% |
| Ages 30–44 | 35.2% |
| Ages 45–64 | 44.3% |
| Ages 65 and older | 45.6% |
The same survey reported 37.2% of men and 40.6% of women aged 18 and older with back pain during the prior 3 months. These are self-reported survey estimates and should not be treated as directly interchangeable with global GBD model estimates.
Race and Hispanic-origin categories in the survey also showed different reported levels:
- 42.7% of non-Hispanic White adults reported back pain.
- 35.8% of non-Hispanic Black adults reported back pain.
- 31.2% of Hispanic adults reported back pain.
- 24.5% of non-Hispanic Asian adults reported back pain.
Income categories showed another gradient in the 2019 U.S. estimate: 44.8% of adults below 100% of the federal poverty level reported back pain, compared with 40.6% at 100%–199% of the federal poverty level and 37.6% at 200% or more of that level. The federal poverty level bands are survey classifications, not measures of individual cause.
Work-Related Low Back Pain Among U.S. Workers
The CDC/NIOSH report “Prevalence, Recognition of Work-Relatedness, and Effect on Work of Low Back Pain Among U.S. Workers” analyzed workers employed during the interview week in the 2015 National Health Interview Survey Occupational Health Supplement. Former workers were excluded, and the estimates were limited to workers who answered the supplemental items.
| 2015 U.S. worker outcome | Share of workers |
|---|---|
| Any low back pain | 26.4% |
| Frequent and severe low back pain | 8.1% |
| Low back pain attributed to work by a health professional | 5.6% |
“Frequent and severe” is the study’s outcome definition. The 5.6% figure requires attribution by a health professional, so it does not represent all back pain experienced while working or all pain that may affect work.
Global Low Back Pain Burden Among Adults Aged 55 and Older
A peer-reviewed analysis, “Global, regional, and national burden of low back pain for adults aged 55 and older 1990–2021”, used GBD 2021 modeled estimates. For global adults aged 55 and older in 2021, it estimated:
- 271,680,057 prevalent cases, with a 95% uncertainty interval of 230,309,073–316,720,242.
- 109,855,844 incident cases, with a 95% uncertainty interval of 91,292,145–128,356,824.
- 29,470,959 years lived with disability, with a 95% uncertainty interval of 20,299,620–39,656,202.
The corresponding global age-standardized measures were 18,282.8 prevalent cases per 100,000, 7,392.8 new cases per 100,000, and 1,983.3 YLDs per 100,000. YLD means years lived with disability, and these rates are modeled, age-standardized burden measures rather than counts from a household survey.
Between 1990 and 2021, the global age-standardized prevalence rate for this age group fell 10.4%, the incidence rate fell 9.4%, and the YLD rate fell 11.0%. These rate declines do not mean that absolute case counts fell; population ageing and growth can increase the number of people affected.
Regional and Country Variation in Older-Adult Back Pain
The GBD 2021 analysis reported substantial variation in age-standardized rates among adults aged 55 and older. The following figures are for 2021 and are not directly comparable with the U.S. NHIS percentages because they use modeled rates and a different population definition.
| Geography | Prevalence per 100,000 | Incidence per 100,000 | YLDs per 100,000 |
|---|---|---|---|
| Central Europe | 29,992.8 | 11,201.3 | 3,238.5 |
| Eastern Europe | 29,323.7 | 11,205.1 | 3,154.5 |
| Australasia | 23,432.2 | 9,231.9 | 2,543.4 |
| Andean Latin America | 13,463.6 | 5,647.5 | 1,472.0 |
| East Asia | 14,011.2 | 5,861.2 | 1,540.5 |
At the national level, Hungary had the highest age-standardized prevalence rate among adults aged 55 and older, at 32,592.8 per 100,000, while the Maldives had the lowest, at 12,300.5 per 100,000. Ukraine had the highest national incidence rate, at 11,775.2 per 100,000, and the Maldives had the lowest, at 5,210.0 per 100,000.
For YLDs, Hungary had the highest national age-standardized rate at 3,508.1 per 100,000, while Myanmar had the lowest at 1,348.4 per 100,000. These country comparisons cover 204 countries and territories and retain uncertainty in the underlying source evidence.
Back Pain Trends and Modeled Risk Factors
For global adults aged 55 and older in 2021, the GBD analysis estimated that occupational ergonomic factors accounted for 15.0% of low back pain YLDs, smoking for 13.5%, and high BMI for 13.4%. These are population-attributable modeled estimates, not proof that any one factor caused an individual’s pain.
The modeled high-BMI attribution ranged from 6.2% in South Asia to 21.9% in high-income North America. The smoking attribution ranged from 4.5% in Western Sub-Saharan Africa to 17.6% in Central Europe.
Occupational ergonomic attribution ranged from 6.9% in Eastern Europe to 38.3% in Eastern Sub-Saharan Africa. Regional fractions describe modeled population-level patterns, not a clinical risk estimate for every person in those regions.
The 1990–2021 trend also differed by geography:
- Tropical Latin America had a 7.7% increase in the age-standardized prevalence rate among adults aged 55 and older.
- East Asia had a 17.6% decrease in the age-standardized prevalence rate for adults aged 55 and older.
- Taiwan had a 31.3% increase in the age-standardized prevalence rate for adults aged 55 and older.
All three trend figures are GBD modeled changes in age-standardized prevalence rates, not continuous surveillance counts. The dataset combines WHO summaries, U.S. survey estimates, and GBD modeled measures, so differences in population, recall window, definition, and uncertainty should be considered when comparing them.
