Perceived
Snakes are a textbook example of a prepared fear — ophidiophobia is one of the most commonly reported specific phobias in the general population, and the imagery of a venomous bite is culturally ancient. But "fear of snakes" as measured in surveys bundles the phobia with garden-variety squeamishness, and no rigorous recent poll isolates "fear of being killed by a venomous snake bite" from that broader bucket. The perceived side here is marked intuition rather than survey.

~5 venomous snake bite deaths per year (US)
US adults
Show derivation
Uses ~5 venomous snake bite deaths per year in the United States (CDC NIOSH) across a US adult population of ~260 million, giving an annual per capita risk of ~1.9e-8. Compounded over 59 years of remaining adult life. The Greene et al. (2021) 30-year average of ~3.4 fatal bites per year is slightly lower and sits inside the uncertainty band.

This is a US-population-level figure. It does not apply globally: snakebite envenoming is one of the world's most important neglected tropical diseases, killing an estimated 81,000-138,000 people per year, almost entirely in South Asia and sub-Saharan Africa where antivenom access is limited. It also does not apply uniformly within the US — fatal bites concentrate heavily in southern and midwestern states and almost entirely in rattlesnake-range outdoor exposures.

Snake bites are one of the rarest causes of death on the US risk ledger. The CDC’s occupational-safety division reports roughly 7,000 to 8,000 venomous snake bites per year in the United States and about five deaths. A 30-year review in the American Journal of Emergency Medicine (Greene et al., 2021) identified only 101 fatal native-snake bites across all of 1989-2018 — an average of about 3.4 per year, over 90% of them from rattlesnakes. Apportioned across US adults and compounded over a working lifetime, that works out to roughly 1 in 880,000.
That puts fatal snakebite in the same order of magnitude as being killed by lightning (~1 in 1.2M) and a couple of times rarer than dying from a bee, wasp, or hornet sting (~1 in 18,000). The irony runs deep here: snakes are one of the most commonly feared animals on Earth, yet in the US, the average person is roughly 100 times more likely to die from a bee, wasp, or hornet sting, and about three times more likely to be killed by a lightning strike. Fatal snakebite is, for the US adult, a statistical footnote.
The number does not travel. Globally, snakebite envenoming kills an estimated 81,000 to 138,000 people every year (WHO) — most of them agricultural workers in rural South Asia and sub-Saharan Africa, where antivenom is expensive, cold-chain distribution is thin, and a bite several hours from a clinic is often fatal. The WHO classifies it as a neglected tropical disease for exactly that reason. If you farm barefoot in rural Uttar Pradesh, the US figure on this page is the wrong baseline for you by roughly four orders of magnitude. If you live in a US city and your outdoor exposure is hiking trails and lawns, it is, if anything, an overestimate.

Venomous Snakes at Work- Statistic
7,000-8,000 venomous snake bites per year in the US; about 5 deaths- Excerpt
“"Each year, 7,000-8,000 people are bitten by venomous snakes in the United States. About 5 of those people die. The number of deaths would be much higher if people did not seek medical care." ”

- Calculation
- CDC NIOSH gives the round-number US figure of ~5 deaths per year. Dividing by a US adult population of ~260M gives ~1.9e-8 per adult per year; compounded over 59 years of remaining adult life yields the normalized lifetime figure of roughly 1 in 880,000.
- Independence
- CDC NIOSH occupational-safety summary consolidates multiple US public-health data streams (WONDER, AAPCC NPDS, CDC surveillance). Partially overlaps with the upstream sources used by Greene et al., so is not fully independent of the peer-reviewed figure below.

Epidemiology of fatal snakebites in the United States 1989-2018- Statistic
101 fatal native-snake bites in the US over 1989-2018 (~3.4 per year); 90.2% rattlesnakes- Excerpt
“"We identified 101 fatal bites from native snakes... Rattlesnakes accounted for 74 (90.2%) of the 82 deaths for which the species was known or which occurred where rattlesnakes are the only native crotalids. There were five fatalities attributed to copperheads, two due to cottonmouths, and one caused by an eastern coral snake." ”

- Calculation
- Greene et al.'s 30-year average (~3.4 deaths/year) is the peer-reviewed lower bound and corroborates the CDC figure. Using this figure instead of 5 would shift the lifetime estimate to ~1 in 1.3M. The uncertainty band spans both.
- Independence
- CDC NIOSH and Greene et al. draw from overlapping but not identical case pools (NIOSH summarizes multiple public-health sources; Greene et al. use AAPCC NPDS plus CDC WONDER death certificates), so this counts as meaningful independent corroboration.

Global snakebite deaths: 81,410-137,880 per year- Excerpt
“"Around 81 410 to 137 880 people die each year because of snake bites, and around three times as many amputations and other permanent disabilities are caused by snakebites annually." ”

- Calculation
- Included as context for the global asymmetry: snakebite is a major neglected tropical disease globally, but the US-specific fatality rate is roughly four orders of magnitude lower per capita than the South Asian and sub-Saharan African rates that drive the global total. We normalize on the US figure, not this one.
- Independence
- WHO figure derives primarily from Kasturiratne et al. (2008) and subsequent country-level verbal autopsy studies; independent of the US-centric CDC and AAPCC data.
