High blood pressure among adults

US estimate 34.4% (95% interval 34.0–34.7), age-adjusted 30.7% (30.4–31.0). Published in the 2022, 2023, 2024, 2025 releases.

High blood pressure among adults: CDC's PLACES 2025 release estimates 34.4% nationally (95% confidence interval 34.0–34.7%), or 30.7% age-adjusted, from 2023 BRFSS responses.

Across the 2,956 counties with a 2025 estimate, the median county is 38.5% and the middle half of counties fall between 35.3% and 42.0%; the full range runs from 17.3% to 59.8%. Population-weighted state figures computed by this site (no interval) range from 27.0% (Colorado) to 44.9% (Mississippi).

CDC advises that areas may be compared on individual measures but that the estimates should not be used to rank overall health; the county lists below are ordered by point estimate and every row carries its 95% confidence interval.

CDC's definition

A multi-level regression and post-stratification approach was applied to BRFSS and ACS data to compute a detailed probability among adults who report ever having been told by a doctor, nurse, or other health professional that they have high blood pressure. Women who were told they had high blood pressure only during pregnancy and those who were told they had borderline hypertension are not included. The probability was then applied to the detailed population estimates at the appropriate geographic level to generate the prevalence. The 95% confidence interval was derived using Monte Carlo simulation.

CDC's notes: Indicator does not measure the proportion of adults who currently have undiagnosed high blood pressure and thus likely results in an underestimate of the prevalence of high blood pressure. Indicator is based on having been told that one has high blood pressure and is subject to recall and actually having been told. Additionally, reports are not validated against actual blood pressure measurements or medical records. Survey questions are part of the BRFSS Rotating Core (odd years).

Quoted from CDC's PLACES measure definitions (cdc.gov/places/measure-definitions). BRFSS is the Behavioral Risk Factor Surveillance System, the telephone survey the model is trained on.

National distribution across counties

17.3%38.6%59.8%

Crude county point estimates in the 2025 release, 24 equal bins. Deciles: 10th 32.0%, 25th 35.3%, median 38.5%, 75th 42.0%, 90th 45.9%. Counties without a 2025 estimate (Kentucky, Pennsylvania and the states without the social-needs module) are excluded here.

By state

Crude prevalence is the estimated share of all adults. Age-adjusted prevalence is standardised to the 2000 US standard population so that areas with different age structures can be compared. CDC: "Age-adjusted estimates are only available at the county and place-level."

State figures are population-weighted county estimates computed by this site (PLACES publishes no state row) and carry no interval; they are listed by point estimate, which is not a ranking of states' health. Lowest and highest county columns are crude point estimates. * This measure was not published for the state in the 2025 release; its figure, county count and county range come from the release in brackets, the most recent that has them.

Questions and answers

How does PLACES define "high blood pressure among adults"?

A multi-level regression and post-stratification approach was applied to BRFSS and ACS data to compute a detailed probability among adults who report ever having been told by a doctor, nurse, or other health professional that they have high blood pressure. Women who were told they had high blood pressure only during pregnancy and those who were told they had borderline hypertension are not included. The probability was then applied to the detailed population estimates at the appropriate geographic level to generate the prevalence. The 95% confidence interval was derived using Monte Carlo simulation. Population: All Adults. Time period of case definition: Past 12 months.

What is the national estimate for high Blood Pressure?

34.4% (95% confidence interval 34.0–34.7%) crude and 30.7% age-adjusted in the 2025 release.

Which counties have the highest and lowest estimates?

The highest county point estimate is 59.8% (Greene County, AL) and the lowest 17.3% (Madison County, ID). Because the intervals for neighbouring positions usually overlap, the lists are a reference for point estimates, not a ranking.

Is a higher figure better or worse?

This site does not grade measures. CDC groups them as health outcomes, prevention, health risk behaviors, disability, health status and health-related social needs; for prevention measures such as checkups and screening a higher share reports the service, for the others a higher share reports the condition or circumstance.
