America stopped adding healthy years in 2010
Healthy life expectancy in the United States reached 66.6 years in 2010 and has not exceeded it since. Over the following nine years it fell to 66.0, while total life expectancy over the same period edged up from 78.6 to 78.7. Both figures come from the WHO. By 2021 life expectancy was 0.3 years below its 2000 level and healthy life expectancy was 1.4 years below — the losses fell disproportionately on years spent in good health.
The years America was still adding to life after 2010 were not healthy ones: total life expectancy held steady through that decade while healthy life expectancy fell every measured year from 2012.
What actually happened in 2010?
Healthy life expectancy hit 66.6 years and stopped. It held at 66.6 through 2011 and 2012, then fell in every measured year after: 66.5, 66.3, 66.2, and 66.0 by 2017, where it stayed to 2019. Nothing in the total life-expectancy series marks 2010 as unusual — it was still 78.6 that year and 78.7 nine years later. The turning point is only visible in the health-adjusted measure.
Why chart two life expectancies at all?
Because they answer different questions. Life expectancy at birth counts years lived. HALE counts the years lived in full health, so the gap between them is years lived with illness or disability. A country can extend the first without extending the second, and when it does, the extra years are being added to the unhealthy portion. That is precisely what the American figures show after 2010.
How much of an American life is spent in poor health?
On these figures, 11.4 years in 2000 and 12.7 years by 2019 — the widest point in the series. The gap widened by more than a year over two decades, and after 2010 it widened without life expectancy rising, which means it widened because health deteriorated rather than because longevity improved. In 2021 the gap was 12.5 years, narrower than 2019 only because both measures had fallen.
Isn’t this just COVID?
The 2020–21 collapse is real and large: life expectancy fell from 78.7 to 76.4 and HALE from 66.0 to 63.9 in two years. But the divergence starts a decade earlier. Between 2010 and 2019 — before any pandemic year — healthy life expectancy fell 0.6 years while life expectancy rose 0.1. A chart that begins in 2019 would miss the entire finding.
What can’t this data tell you?
Why. HALE is built from mortality data combined with modelled estimates of disability prevalence, and this page does not carry the disease-level detail that would attribute the decline to any specific cause. WHO also publishes confidence intervals with both series which are not charted here, so small year-to-year moves should be read as estimates rather than measurements. The direction over a decade is the claim; a single year is not.
How this was measured
- Indicator
- — WHO Global Health Observatory — life expectancy at birth (WHOSIS_000001) and healthy life expectancy, HALE (WHOSIS_000002), both sexes
- What it means
- — Life expectancy at birth is the average years a newborn would live at current mortality rates. HALE is the portion of those years spent in full health, so it always sits below life expectancy; the difference is years lived with illness or disability. Both are modelled estimates and WHO publishes confidence intervals with them that this page does not chart.

Common questions
What is healthy life expectancy (HALE)?
The average number of years a newborn would live in full health at current rates of mortality and ill health. It is always lower than total life expectancy, and the difference between the two is the number of years expected to be lived with illness or disability. WHO publishes both for every member state.
Is American life expectancy lower than it was in 2000?
On WHO’s figures, yes — 76.4 years in 2021 against 76.7 in 2000. Healthy life expectancy fell further, from 65.3 to 63.9. Those are pandemic-affected years; the point this page makes about 2010 does not depend on them, because it rests on the 2010–2019 window instead.
Where does this data come from and can I check it?
The WHO Global Health Observatory, indicators WHOSIS_000001 and WHOSIS_000002, both sexes, pulled 2026-07-26. Using one publisher for both series is deliberate: pairing WHO’s HALE with another body’s life expectancy would make the gap partly an artefact of two estimation methods.
