How common is obesity where you live? The table below shows the share of adults with obesity in every state and the District of Columbia, from the newest CDC survey data (2025, released September 2026). It is the starting point for our state guides, which look at what actually shapes weight and activity in a place: weather and seasons, work schedules and commutes, trails, and local food.

How to read these numbers
- It is a survey. BRFSS is a large state-run phone survey. People report their own height and weight, and self-reports tend to understate weight, so true rates are likely somewhat higher everywhere.
- Look at the confidence interval. Each figure is an estimate. When two states’ intervals overlap, the difference between them may not be real.
- BMI describes groups, not individuals. A BMI of 30 or more is the standard screening cutoff for obesity in adults, but BMI does not measure body fat, muscle or health directly.
- Single-year moves are noisy. A one-point rise or fall from 2024 to 2025 is usually within the margin of error. Trends over several years say more.
Frequently asked questions
Which state has the highest adult obesity rate in 2025?
Alabama, at 39.7% of adults, followed by North Dakota (39.1%) and Kentucky (38.8%). No state reached 40% in the 2025 survey.
Which state has the lowest adult obesity rate?
Among states, Colorado has the lowest rate at 25.7%, followed by Hawaii at 26.4%. The District of Columbia is lower still, at 24.2%.
Why do California, Mississippi and Nevada show no 2025 number?
CDC did not publish a 2025 all-adult estimate for these states because the survey data did not meet its standards for that year. The table shows each state’s 2024 figure instead, labeled as 2024.
Does a state’s obesity rate say anything about my own health?
No. These are population averages based on body mass index (BMI). BMI is a screening measure for groups. It does not account for muscle, body fat distribution or individual health, so it cannot tell you whether your own weight is a problem.
