Over the last hundred years, the number of deaths per year from natural disasters has significantly decreased. Annual deaths from natural disasters have decreased by approximately 75% compared to a century ago. Around 1907 to 1916, the average number of deaths per year was over 325,000, while in the most recent decade (2007 to 2016), the average dropped to about 80,000 deaths per year despite the global population increasing substantially over the same period. More specifically, in the 1920s, yearly deaths from climate-related disasters (including floods, droughts, storms, and wildfires) averaged around 485,000, whereas in the period 2010-2019, the average was about 11,000 — a decline of over 97% in climate-related disaster deaths. Death tolls from natural disasters have shown steady declines throughout the decades, with deaths in the 1970s being over 50,000 per year and reducing to less than 20,000 in the 2010s. This trend is linked to improvements in disaster preparedness, warning systems, and responses worldwide. Though deaths have decreased, the number of natural disasters and economic losses have increased due to factors like population growth and urbanization. The majority of disaster deaths are still concentrated in developing countries. In summary, natural disaster mortality has declined dramatically over the last century while the frequency and cost of disasters have tended to rise.
