United States · 2018–2024

The curve that climbed, then bent.

For six years the rate of drug overdose death in America rose almost without pause. In 2024 it fell harder than it had ever risen.

A reading of the national mortality record Rates per 100,000 · age-adjusted

● Age-adjusted deaths per 100,000 residents, all drug overdoses

A rate is a quieter number than a count, and a more honest one. It asks not how many died but how common dying this way became — deaths per 100,000 people, adjusted so that an older population is not mistaken for a sicker one. By that measure the country went from 20.7 in 2018 to a peak of 32.6 in 2022: a level of overdose death with no precedent in the modern record.

Then the line did something it had not done in a decade. It turned down — slightly in 2023, and then, in 2024, it dropped to 23.1, the lowest figure since before the pandemic. This is the story of that shape: what drove it up, who it reached, and why the fall, though real, is not yet a recovery.

How to read these numbers Every figure here is a rate — deaths per 100,000 residents — not a body count. Most are age-adjusted so groups with different age structures can be compared fairly. And because a single death can involve more than one drug, the drug categories below overlap and are not meant to be added together.

One drug bent the whole curve

The epidemic became a fentanyl epidemic.

Pull the total apart by the type of drug involved and a single line dominates everything around it — synthetic opioids, overwhelmingly illicit fentanyl. Heroin, its predecessor, all but vanished from the record.

Age-adjusted death rate by drug type involved, 2018–2024. Synthetic opioids other than methadone — chiefly illegally made fentanyl — rose from 9.9 to a peak of 22.7, then fell by more than a third in a single year. Heroin fell every year, from 4.7 to 0.8, as fentanyl displaced it in the illicit supply. Lines overlap because one death can involve several drugs; they do not sum to the total.

Why the lines don't add up Add the four opioid subtypes for 2022 and you get 29.0 — more than the 25.0 rate for "any opioid," and close to the 32.6 all-drug total. That is not an error. Roughly half of these deaths involve more than one substance at once, so each is counted under every drug it touched. Treat these as overlapping circles, never as slices of a pie.

The toll moved

It stopped being a story about one group.

In 2018, White Americans had the highest age-adjusted overdose rate of any major group. Within a few years the burden had shifted — and by the peak years it fell hardest on American Indian and Alaska Native and on Black communities.

Age-adjusted all-drug overdose death rate by race and Hispanic origin. The American Indian and Alaska Native rate climbed from 26.8 to 65.2 — the highest of any group in every year after 2019. The Black rate more than doubled, overtaking the White rate around 2020. Every group's rate fell in 2024, but the gaps opened during the crisis have not closed.

Who, by age and sex

A crisis of the middle of life.

Overdose death is not spread evenly across a lifetime. It concentrates in working age — and within every age band, men die at roughly two to three times the rate of women.

Crude overdose death rate by age group, 2018–2024. Age-specific rates are shown crude (they cannot be age-adjusted). The rate peaks among adults 35–44, and the 2024 decline reaches every working-age band — yet among adults 65–74 the rate kept climbing through 2023, a reminder that an aging cohort carries the epidemic forward with it.

The reversal of 2024

For once, it fell for everyone.

The remarkable thing about 2024 is not only that the rate dropped, but that it dropped across every group at once. No major demographic was left behind by the decline — though some had far more height to fall from.

Change in age-adjusted all-drug overdose rate, 2023 → 2024. Each line runs from the 2023 rate (○) to the 2024 rate (●). Every group fell. The steepest proportional drops were among Black Americans (−31%) and men (−27%); the groups starting highest, American Indian and Alaska Native communities, fell least in proportional terms and remain far above everyone else.

What the fall does and doesn't mean

A bent curve is not a closed chapter.

The 2024 decline is the largest the country has recorded, and it is broad and real. But the year still ended with an age-adjusted rate of 23.1 — higher than any year before 2020, and behind that rate stand tens of thousands of deaths. The line returned roughly to where it stood in 2019, the year before the pandemic; it did not return to safety.

Why it fell is genuinely uncertain. Researchers have offered several explanations — wider distribution of naloxone, better access to treatment, shifts in an illicit supply that may be saturating or changing — and none has been proven dominant. There is also a grimmer possibility that some of the decline reflects how many people at highest risk had already died. What the data here can show is the shape and the spread of the change. It cannot, on its own, tell us whether the curve will keep bending.

Scope of this record These figures track all drug overdose deaths and their opioid components. They do not isolate stimulants such as cocaine and methamphetamine, which the same surveillance system tracks separately and which moved on their own trajectory over these years.
