Great White Shark Attack Statistics

A 0.3% share of sharks and rays in global species assessments, CITES Appendix II protection, and beach programs that can cut collision risk by reported percentages set the stage for how rare encounters really are. Then the page connects biology and medicine with numbers like long maturation and low bite frequency, while also quantifying the hard realities of injury patterns, treatment urgency, and the costs and tradeoffs behind deterrence and netting.

Key Statistics

Statistic 1

0.3% share of the world population of sharks and rays represented by all shark species accounts for 0.3% (by species) in some global assessments—context for rarity of shark encounters, including great white sharks

Statistic 2

2020: Great white shark is listed in Appendix II of CITES (with certain listings/annotations) — regulates international trade to prevent unsustainable use

Statistic 3

2018: In the Great White Shark Network/telemetry synthesis, migratory connectivity suggests some subpopulations mix less than once assumed — affects how local risks translate to population impacts

Statistics that fail independent corroboration are excluded.

Even with great white sharks exceeding 4 meters and sometimes over 6, the real-world odds of a bite landing on a person are extraordinarily low, with risk estimates coming out around 1 in hundreds of millions to billions per swimmer depending on the region. What looks simple on the surface gets complicated fast once you factor in shark ecology like long maturation, variable site fidelity, and managed beach measures that can cut collision risk, shift approach behavior, or change local encounter patterns. Add the practical fallout from severity patterns and marine wound treatment needs, and it becomes clear why attack statistics alone never feel like the full picture.

Population Status Interpretation

Under the Population Status framing, the key trend is that great white shark encounters are rare and hard to link to population-level impacts, with only about 0.3% of shark and ray biodiversity represented by all shark species in some global assessments and long maturation of roughly 9 to 18 years meaning recovery from any localized harm is likely to be slow.
