Your odds of dying in a natural disaster have fallen sharply in a century
Deaths from natural disasters per 100,000 people, decadal average
Earthquakes, floods, droughts, and storms still strike as often as they ever did, and the number of people in harm's way keeps growing. Yet the share of us they kill has fallen a long way over the last century.
The key rows
From the record
Over the last century, death rates have fallen by more than 90%.
The reason is not calmer weather. It is forecasting, early warning, sturdier buildings, and faster rescue, all of which turn a disaster that once meant mass death into one that far more people survive. Because rare mega-events dominate the yearly numbers, this series is a decadal average, which shows the underlying trend rather than the noise.
Asked often
Are natural disasters killing fewer people than they used to?
Yes. The decadal death rate from natural disasters fell from 8.99 per 100,000 people in the 1900s to 0.59 in the 2020s, even as more people live in exposed places.
Why show a decadal average instead of yearly deaths?
Disaster deaths are dominated by rare mega-events, so single years swing wildly. Averaging by decade reveals the long-run downward trend instead of the noise.
Why have disaster deaths fallen despite population growth?
Better forecasting, early-warning systems, sturdier infrastructure, and faster emergency response have sharply cut deaths per person even as more people are exposed to hazards.
