Overweight statistics at a glance
Overweight is one of the most common adult health classifications in the world, and the numbers show how broad the pattern has become. The dataset points to a global challenge that is no longer limited to a single region, age group, or income band.

What the overweight statistics show
The most useful way to read these numbers is to separate prevalence, count, and classification.
- Prevalence shows how common overweight or obesity is within a population.
- Counts show how many people the condition affects.
- Classification defines the threshold used to label adults and children.
That matters because a large share and a large absolute count can both be true at the same time. In 2022, the world had 2.5 billion adults aged 18+ who were overweight and 890 million adults living with obesity (WHO obesity and overweight fact sheet). Those figures do not describe a niche issue. They describe a mass-pattern health trend.
Big number: 43% of adults aged 18+ were overweight worldwide in 2022 (WHO obesity and overweight fact sheet).
The same source also shows that obesity is now deeply embedded alongside overweight. 16% of adults aged 18+ were living with obesity in 2022, and global adult obesity prevalence had more than doubled since 1990 (WHO obesity and overweight fact sheet). The relationship is important: overweight is not just a lighter category that sits apart from obesity. It sits on the same population curve.
Global overweight trends and thresholds
The global figures give a clear picture of scale, but the thresholds explain how the category is defined.
Adult classification thresholds
- Adults are classified as overweight at BMI 25 or higher (WHO obesity and overweight fact sheet).
- Adults are classified as obese at BMI 30 or higher (WHO obesity and overweight fact sheet).
Child classification thresholds
- Children aged 5-19 are classified as overweight above 1 standard deviation over the WHO Growth Reference median (WHO obesity and overweight fact sheet).
- Children aged 5-19 are classified as obese above 2 standard deviations over the WHO Growth Reference median (WHO obesity and overweight fact sheet).
- Children under age 5 are classified as overweight above 2 standard deviations over the WHO Child Growth Standards median (WHO obesity and overweight fact sheet).
- Children under age 5 are classified as obese above 3 standard deviations over the WHO Child Growth Standards median (WHO obesity and overweight fact sheet).
These thresholds matter because they shape how prevalence is counted. A change in definition changes the headline number, but the dataset is already large even before any interpretation. In 2022, the WHO estimates show a world where overweight is common among adults and increasingly visible among children and adolescents.
Global adult overweight and obesity in one view
| Measure | Latest figure | Source |
|---|---|---|
| Adults aged 18+ overweight worldwide | 2.5 billion in 2022 | WHO obesity and overweight fact sheet |
| Adults aged 18+ overweight prevalence | 43% in 2022 | WHO obesity and overweight fact sheet |
| Adults aged 18+ living with obesity worldwide | 890 million in 2022 | WHO obesity and overweight fact sheet |
| Adults aged 18+ obesity prevalence | 16% in 2022 | WHO obesity and overweight fact sheet |
| Adults aged 18+ obesity trend | More than doubled since 1990 | WHO obesity and overweight fact sheet |
The table shows a pattern worth keeping in mind: the overweight base is much wider than obesity, but both indicators are already large enough to shape public health planning, consumer behavior, and clinical workload.
U.S. adult overweight and obesity data
The U.S. numbers provide a useful contrast because they show long-run trend data alongside a recent prevalence snapshot.
Latest adult snapshot
In 2017-March 2020, 41.9% of U.S. adults aged 20+ had obesity (CDC Adult Obesity Facts). That means more than 100 million U.S. adults have obesity based on that prevalence estimate (CDC Adult Obesity Facts).
The same CDC source reports 9.2% severe obesity among U.S. adults aged 20+ in the same period, equal to more than 22 million U.S. adults (CDC Adult Obesity Facts). The severity measure matters because it points to higher risk and higher resource use, not just a larger prevalence count.
U.S. adult trend line
The trend table shows how fast obesity climbed over time.
| Period | U.S. adult obesity prevalence | Source |
|---|---|---|
| 1999-2000 | 30.9% | CDC NHANES adult trend table |
| 2005-2006 | 34.3% | CDC NHANES adult trend table |
| 2017-2018 | 42.4% | CDC NHANES adult trend table |
The increase is substantial over a relatively short span. The CDC also reports 30.5% in 1999-2000 to 41.9% in 2017-March 2020 for U.S. adults aged 20+ in the adult obesity facts dataset (CDC Adult Obesity Facts). Even when the periods differ slightly across CDC tables, the direction is consistent: obesity prevalence moved upward and stayed there.
Overweight as a separate U.S. adult measure
The dataset also includes 31.1% overweight prevalence among U.S. adults aged 20+ by crude estimate in 2017-2018 (CDC NHANES adult trend table).
That figure is useful because it shows overweight remains a large category even when obesity is the headline measure. In practical terms, many adults sit in the BMI range above healthy weight without crossing into obesity, which means overweight statistics remain important in their own right rather than as a footnote to obesity data.
Youth overweight and obesity statistics
The youth data show why overweight and obesity are often discussed together. These are not only adult conditions.
Global child and adolescent counts
- 35 million children under age 5 were overweight worldwide in 2024 (WHO obesity and overweight fact sheet).
- More than 390 million children and adolescents aged 5-19 were overweight worldwide in 2022 (WHO obesity and overweight fact sheet).
- 160 million children and adolescents aged 5-19 were living with obesity worldwide in 2022 (WHO obesity and overweight fact sheet).
Those three lines show that the issue spans both very young children and older youth. The count of overweight children and adolescents is especially important because it captures a much broader base than obesity alone.
U.S. child and adolescent obesity
The CDC childhood dataset gives a direct look at age splits.
| Age group | U.S. obesity prevalence | Source |
|---|---|---|
| Ages 2-5 | 12.7% | CDC Childhood Obesity Facts |
| Ages 6-11 | 20.7% | CDC Childhood Obesity Facts |
| Ages 12-19 | 22.2% | CDC Childhood Obesity Facts |
| Ages 2-19 overall | 19.7% | CDC Childhood Obesity Facts |
The progression by age is notable. Obesity prevalence rises from 12.7% in ages 2-5 to 22.2% in adolescents ages 12-19 (CDC Childhood Obesity Facts). That pattern matters because later childhood and adolescence often carry more established behavior, school, and environment effects than the preschool years.
The CDC also estimates about 14.7 million U.S. youths ages 2-19 had obesity in 2017-March 2020 (CDC Childhood Obesity Facts). That count turns the prevalence rate into a household-scale issue rather than a narrow clinical one.
Youth disparities by race and sex
The dataset shows substantial variation among U.S. children.
- Hispanic U.S. children had obesity prevalence of 26.2% (CDC Childhood Obesity Facts).
- Non-Hispanic Black U.S. children had obesity prevalence of 24.8% (CDC Childhood Obesity Facts).
- Non-Hispanic White U.S. children had obesity prevalence of 16.6% (CDC Childhood Obesity Facts).
- Non-Hispanic Asian U.S. children had obesity prevalence of 9.0% (CDC Childhood Obesity Facts).
- Among U.S. girls, non-Hispanic Black girls had the highest obesity prevalence at 30.8% (CDC Childhood Obesity Facts).
- Among U.S. boys, Hispanic boys had the highest obesity prevalence at 29.3% (CDC Childhood Obesity Facts).
These differences show why a single national average is not enough for planning. The averages hide the fact that some groups are far above the overall prevalence.
Demographic patterns in the U.S.
Adult obesity is not evenly distributed across race, education, or age. The CDC data make that clear.
Race and ethnicity
| Group | U.S. adult obesity prevalence | Source |
|---|---|---|
| Non-Hispanic Black adults | 49.9% | CDC Adult Obesity Facts |
| Hispanic adults | 45.6% | CDC Adult Obesity Facts |
| Non-Hispanic White adults | 41.4% | CDC Adult Obesity Facts |
| Non-Hispanic Asian adults | 16.1% | CDC Adult Obesity Facts |
The gap is wide. Non-Hispanic Black U.S. adults had the highest obesity prevalence at 49.9%, while non-Hispanic Asian adults were at 16.1% in 2017-March 2020 (CDC Adult Obesity Facts). That is a spread of more than 30 percentage points.
The NHANES race table reinforces the pattern:
- Non-Hispanic White adults: 42.2% (CDC NHANES race table).
- Non-Hispanic Black adults: 49.6% (CDC NHANES race table).
- Non-Hispanic Asian adults: 17.4% (CDC NHANES race table).
- Hispanic adults: 44.8% (CDC NHANES race table).
- Mexican American adults: 50.4% (CDC NHANES race table).
Education
Education also tracks strongly with obesity prevalence.
- Adults with a high school diploma or some college had obesity prevalence of 46.4% (CDC Adult Obesity Facts).
- Adults with less than a high school diploma had obesity prevalence of 40.1% (CDC Adult Obesity Facts).
- Adults with a college degree or above had obesity prevalence of 34.2% (CDC Adult Obesity Facts).
The 2024 geographic dataset shows a similar education split:
- Adults without a high school diploma: 37.6% (CDC Adult Obesity Prevalence Maps).
- Adults with a high school diploma: 35.4% (CDC Adult Obesity Prevalence Maps).
- Adults with some college education: 35.7% (CDC Adult Obesity Prevalence Maps).
- College graduates: 27.3% (CDC Adult Obesity Prevalence Maps).
Education does not operate in isolation, but the gradient is persistent. Higher educational attainment is associated with lower obesity prevalence in both the adult facts table and the 2024 maps dataset.
Age
Age shapes prevalence as well.
- Obesity prevalence was 39.8% among adults aged 20-39 (CDC Adult Obesity Facts).
- Obesity prevalence was 44.3% among adults aged 40-59 (CDC Adult Obesity Facts).
- Obesity prevalence was 41.5% among adults aged 60+ (CDC Adult Obesity Facts).
The 2017-2018 NHANES age table shows a similar pattern for men and women:
- Men aged 20-39: 34.1% (CDC NHANES adult age table).
- Men aged 40-59: 43.5% (CDC NHANES adult age table).
- Men aged 60+: 42.2% (CDC NHANES adult age table).
- Women aged 20-39: 39.7% (CDC NHANES adult age table).
- Women aged 40-59: 43.3% (CDC NHANES adult age table).
- Women aged 60+: 43.3% (CDC NHANES adult age table).
Cost and health impact
The health consequences are one part of the story. The financial burden is another.
Medical costs linked to obesity
- Annual medical costs were $1,861 higher per person for U.S. adults with obesity than for adults with healthy weight in 2019 dollars (CDC Adult Obesity Facts).
- Annual medical costs were $3,097 higher per person for U.S. adults with severe obesity than for adults with healthy weight in 2019 dollars (CDC Adult Obesity Facts).
- Total U.S. medical expenditures attributable to obesity were nearly $173 billion in 2019 dollars (CDC Adult Obesity Facts).
Those figures show why obesity and overweight are often discussed together in policy and workplace health settings. Even when overweight is not the same as obesity, it sits in a population pipeline that can drive higher downstream cost.
Common coexisting conditions
Among U.S. adults with obesity:
- 58% also had high blood pressure (CDC Adult Obesity Facts).
- About 23% also had diabetes (CDC Adult Obesity Facts).
That overlap helps explain why overweight and obesity statistics are used well beyond weight-management conversations. They connect directly to hypertension, diabetes, and broader chronic disease planning.
Why the regional split matters
The global regional statistics show that overweight is not evenly distributed.
- In 2022, adult overweight prevalence ranged from 31% in the WHO South-East Asia Region and African Region to 67% in the Region of the Americas (WHO obesity and overweight fact sheet).
- In 2022, adult overweight prevalence was 43% for men and 44% for women globally (WHO obesity and overweight fact sheet).
Regional snapshot
| Region | Adult overweight prevalence | Source |
|---|---|---|
| WHO South-East Asia Region | 31% | WHO obesity and overweight fact sheet |
| WHO African Region | 31% | WHO obesity and overweight fact sheet |
| WHO Region of the Americas | 67% | WHO obesity and overweight fact sheet |
The distance between 31% and 67% is too large to treat overweight as a universal experience. The data say the burden varies sharply by region, and that variation matters for prevention strategies, health budgets, and public messaging.
The U.S. 2024 maps reinforce the same idea at state level. All U.S. states and territories had adult obesity prevalence of at least 25% (CDC Adult Obesity Prevalence Maps). That means the floor is already high. At the same time, the Midwest reached 35.9% and the South reached 34.5%, while the West and Northeast were near 30% (CDC Adult Obesity Prevalence Maps). Several areas pushed much higher: Mississippi, West Virginia, and Guam had adult obesity prevalence of 40% or higher (CDC Adult Obesity Prevalence Maps).
A few more 2024 map facts sharpen the picture:
- 8 states and DC were between 25% and under 30% (CDC Adult Obesity Prevalence Maps).
- 22 states were between 30% and under 35% (CDC Adult Obesity Prevalence Maps).
- 17 states, Puerto Rico, and the Virgin Islands were between 35% and under 40% (CDC Adult Obesity Prevalence Maps).
- Seven geographic areas had obesity prevalence of 35% or higher among adults ages 18-39 (CDC Adult Obesity Prevalence Maps).
- Forty-six geographic areas had obesity prevalence of 35% or higher among adults ages 40-59 (CDC Adult Obesity Prevalence Maps).
- Fourteen geographic areas had obesity prevalence of 35% or higher among adults ages 60+ (CDC Adult Obesity Prevalence Maps).
Those counts show how widespread elevated obesity prevalence has become across age groups and geographies.
The practical takeaway from the data
The dataset points to three broad truths:
- Overweight is widespread globally, with billions of adults affected (WHO obesity and overweight fact sheet).
- Obesity is rising alongside overweight, not replacing it (WHO obesity and overweight fact sheet; CDC Adult Obesity Facts).
- The burden varies sharply by geography, age, race, education, and sex, which means one-size-fits-all responses are unlikely to match the data (CDC Adult Obesity Facts; CDC Childhood Obesity Facts; CDC Adult Obesity Prevalence Maps).
