Wildfire Statistics

With 2020 US wildfire seasons still leaving a long shadow on health, the page connects smoke exposure to emergency department spikes and hospital admissions tied to short term PM2.5 increases, alongside estimates of up to 2,500 US deaths from wildfire smoke each year. It also contrasts scale and risk across regions, from 7.5 million hectares burned globally in 2020 and Australia’s Black Summer to the western US 3.8 times increase in people exposed over 15 years and the costs that follow.

Wildfire statistics have a way of turning “out there” into an everyday health and economic reality, and the most recent smoke and fire-season patterns make that shift hard to ignore. Over the past 15 years, exposure to wildfire smoke in the western US has risen 3.8 times, even as 44,000+ wildfire incidents were reported in the US in 2023. When you connect exposure, air quality, and outcomes, the figures get even more urgent, from PM2.5 spikes to estimated annual smoke-attributable deaths.
