Living Longer vs. Living Healthier: What the Numbers Really Say

Americans are living longer than ever. U.S. life expectancy reached 79.0 years in 2024, the highest on record, according to the CDC. But there's a second number that matters just as much: how many of those years we spend healthy enough to enjoy them.

That's the difference between lifespan (how long you live) and healthspan (how long you live well). The space between them is the years spent living with illness, and it's growing.

The Gap, By the Numbers

Mayo Clinic researchers analyzed World Health Organization data from 183 countries, published in JAMA Network Open. They found:

• The average person worldwide spends 9.6 years in poor health, a gap that grew 13% from 2000 to 2019.
• The U.S. has the largest gap of any country studied: Americans average 12.4 years in poor health, up from 10.9 years in 2000.
• Women's gap is 2.4 years wider than men's, with neurological, musculoskeletal, and urinary conditions adding to the difference.

As senior author Dr. Andre Terzic put it, "gains in longevity are not matched with equivalent advances in healthy longevity."

The CDC's data shows why. In 2023, 76% of U.S. adults (about 194 million people) had at least one chronic condition, and rates among young adults rose 7 percentage points in a decade.

The Good News: Healthy Years Are Within Reach

A Harvard study of more than 111,000 adults found that five habits (not smoking, a healthy weight, 30 minutes of daily activity, moderate alcohol, and a quality diet) made a dramatic difference after age 50:

• Women with four or five habits lived 34.4 years free of diabetes, heart disease, and cancer, compared to 23.7 years with none.
• Men with four or five habits lived 31.1 disease-free years, compared to 23.5.

That's up to a decade of added healthy life, and the study started at 50, proof that midlife is not too late.
