Facts + Statistics: U.S. catastrophes

 
2017 natural catastrophes

Insured losses due to natural disasters in the United States in 2017 totaled $78 billion, according to Munich Re, more than triple the $23.8 billion total for 2016. Tropical cyclones with $49.1 billion in losses accounted for 63 percent of U.S. insured losses in 2017. Severe thunderstorms losses, at $18.2 billion, accounted for about 23 percent of the 2017 insured losses. Wildfires, heat waves and drought produced $9.5 billion in insured losses in 2017, or about 12 percent of total. Winter storms and cold waves caused $1.2 billion in insured losses, and floods and flash floods accounted for $100 million in insured losses in 2017.

 
2016 and 2017 natural and man-made catastrophes

In the first nine months of 2017, the Property Claim Services (PCS) division of Verisk Analytics estimates that direct insured property losses from catastrophes striking the United States were between $36 billion and $40 billion. However, since the three major catastrophes in the third quarter were so large and occurred so close in time to each other, many claims from those events have not been closed. Therefore these ranges are not final.

Property Claim Services (PCS®), a Verisk Analytics® business, defines a catastrophe as an event that causes $25 million or more in insured property losses and affects a significant number of property/casualty (P/C) policyholders and insurers. PCS estimates represent anticipated insured losses from natural and man-made catastrophes on an industrywide basis, reflecting the total net insurance payment for personal and commercial property lines of insurance covering fixed property; vehicles, boats; related-property items; business interruption; and additional living expenses. They exclude loss adjustment expenses. P/C insurance industry catastrophes losses in the United States rose 46 percent to $20.9 billion in 2016 from $15.2 billion in 2015, according to PCS. The number of catastrophes rose to 42 in 2016 from 39 in 2015, the highest number of catastrophes for years with an industry loss event threshold of $25 million.
