Nearly half of all adults in the United States have high blood pressure. Based on the most recent national survey data from August 2021 through August 2023, the prevalence stands at 47.7%, which translates to roughly 120 million adults. That makes hypertension one of the single most common chronic conditions in the country, affecting more people than diabetes, depression, or obesity.
Who Is Most Affected
Men are more likely to have high blood pressure than women. About 50.8% of adult men meet the threshold, compared to 44.6% of adult women. The gap narrows somewhat after age adjustment, but the pattern holds: men carry a consistently higher burden across age groups.
Race and ethnicity play a significant role. Black adults have the highest prevalence at 58.0% after adjusting for age, well above the national average. Among Black women specifically, the rate is 56.7%, which is notably higher than the 36.7% seen in white women and 36.8% in Hispanic women. Among men, the racial gap exists but is smaller: 57.2% for Black men compared to about 50% for both white and Hispanic men.
Age is the strongest individual risk factor. Blood pressure rises steadily as you get older, and the majority of adults over 60 have hypertension. Younger adults aren’t immune, though. A meaningful percentage of people between 18 and 39 already have elevated readings, often without knowing it.
What Counts as Hypertension
The current clinical guidelines, updated in 2025 by the American Heart Association and American College of Cardiology, define two stages. Stage 1 hypertension starts at a systolic reading (the top number) of 130 to 139 or a diastolic reading (the bottom number) of 80 to 89. Stage 2 hypertension is 140 or higher systolic, or 90 or higher diastolic.
These thresholds are lower than what many people expect. Before 2017, the cutoff for hypertension was 140/90. The shift to 130/80 reclassified millions of Americans overnight, which is one reason the prevalence numbers are so high today. The change wasn’t arbitrary. Research showed that cardiovascular risk begins climbing well before blood pressure reaches 140, and earlier intervention reduces heart attacks and strokes.
The Health Toll
High blood pressure damages blood vessels slowly over years, increasing the risk of heart disease, stroke, kidney failure, and vision loss. In 2023, it was a primary or contributing cause of 664,470 deaths in the United States. That figure makes it one of the leading contributors to mortality, rivaling smoking and obesity in its total impact on public health.
The danger of hypertension is partly that it produces no obvious symptoms for most people. You can walk around with a reading of 160/100 and feel perfectly fine, which is why it’s often called a “silent” condition. By the time symptoms appear (severe headaches, shortness of breath, nosebleeds), organ damage may already be underway.
The Control Problem
Having hypertension diagnosed is only half the challenge. A large share of people who know they have it still don’t have it under control, meaning their blood pressure remains above target despite awareness or treatment. The reasons are layered: some people struggle with medication side effects, others face barriers to regular healthcare, and many find it difficult to sustain the lifestyle changes (less sodium, more exercise, maintaining a healthy weight) that can lower readings by 5 to 15 points.
Awareness itself remains incomplete. Millions of adults with high blood pressure have never been told they have it, either because they don’t visit a doctor regularly or because their readings were borderline and went unaddressed. Routine screening is simple (a standard cuff reading takes less than a minute), but getting people into a setting where that happens is a persistent public health gap.
The Financial Cost
Hypertension is expensive both for individuals and for the healthcare system. The CDC estimates that annual costs associated with high blood pressure totaled $219 billion in 2019. On a personal level, adults with hypertension spent roughly $2,760 more per year on medical care than those without it. A 2021 analysis of privately insured adults found an even larger gap: about $2,930 in additional annual costs. These numbers include medications, doctor visits, lab work, and the treatment of complications like heart disease and kidney problems that hypertension accelerates.
For a condition that can often be managed with inexpensive medications and lifestyle changes, the downstream costs of inadequate control are disproportionately high. Much of the spending goes toward treating the consequences of uncontrolled blood pressure rather than preventing them.
Why the Numbers Keep Climbing
Several forces are pushing prevalence upward. The U.S. population is aging, and older adults are far more likely to develop hypertension. Obesity rates continue to rise, and excess weight is one of the strongest modifiable risk factors for high blood pressure. The typical American diet remains high in sodium, with most of it coming not from the salt shaker but from processed and restaurant foods. Physical inactivity compounds the problem.
Stress, poor sleep, and alcohol use also contribute, though their individual effects are harder to quantify at a population level. The net result is a condition that affects nearly one in two adults, costs hundreds of billions of dollars annually, and remains inadequately controlled in a large portion of those who have it.
