Stroke mortality rates in the U.S.

Stroke is the fourth leading cause of death in the U.S. According to the Centers for Disease Control and Prevention (CDC), someone in the U.S. dies of a stroke every 3 minutes and 14 seconds.

Who is most at risk for stroke? Racial and demographic disparities

In the U.S., non-Hispanic Black people face a significantly higher risk of stroke than any other race. The risk is especially high among Black men living in the South.

What are the most common risk factors for stroke?

According to the National Heart, Lung, and Blood Institute (NHLBI), up to 90% of strokes can be prevented by controlling certain risk factors. Here are the top four:

Other top risk factors for ischemic stroke around the world, according to JAHA, include:

Some risk factors vary by gender. For example, high blood pressure, high cholesterol, smoking, and high alcohol use are more likely to be associated with ischemic stroke deaths in men. (JAHA, 2025)

Stroke risk factors may also vary by age. One study found that low physical activity, high blood pressure, heavy alcohol use, and smoking were the top risk factors for stroke among adults younger than 55 years old. ( Stroke, 2017)

When risk factors are out of your control, they’re called non-modifiable. Non-modifiable risk factors for stroke include age, sex, genetics, and having a prior stroke.

Stroke statistics by age

The risk of stroke increases with age, but it’s possible to have a stroke at any age.

Stroke recurrence statistics

Most people who have a stroke have never had one before. But if they have, their second (or third, etc.) stroke is called a recurrent stroke:

Economic cost of stroke

Stroke is an expensive condition to treat and often requires a lengthy hospital stay. But there are other costs associated with stroke, including loss of income and the cost of informal caregiving. Here are some quick statistics about the cost of stroke care in the U.S. and worldwide:

How to reduce stroke risk

“The good news is that many strokes are preventable,” says Sirisha Vadali, MD, a board-certified cardiologist based in Phoenix, Arizona. “The biggest factors people can focus on are controlling blood pressure, managing cholesterol, maintaining healthy blood sugar levels, staying physically active, avoiding tobacco, and prioritizing quality sleep.”

A healthy diet plays a key role in stroke prevention because it can help stabilize blood pressure, cholesterol, and blood sugar. “Small, sustainable lifestyle changes practiced over years can dramatically reduce the likelihood of experiencing a stroke,” Dr. Vadali says. “Prevention is always easier than recovery.”

If you suspect a stroke, call 911 immediately. A stroke is a medical emergency, and timely care significantly affects recovery. The acronym to remember is B.E.F.A.S.T.:

Expert takeaway

“If you are concerned that you or someone near you is having a stroke, call 911. This alerts the emergency medical system, and care starts when they arrive at the scene. The EMS personnel can alert the emergency room staff and stroke care team to streamline evaluation and start treatment,” notes Leslie Greenberg, MD, associate professor of Community and Family Medicine at the University of Nevada, Reno School of Medicine, and member of the SingleCare Medical Review Board.
