ATTOM Data Solutions’ just-released 2016 U.S. Natural Hazard Housing Risk Index found that home sales in the first six months of 2016 increased 4.2 percent from the same time period a year ago in the bottom fifth of U.S. counties with the lowest level of natural hazard risk—more than twice the 1.9 percent increase in the top fifth of U.S. counties with the highest level of natural hazard risk.
For this latest report, more than 3,000 U.S. counties were indexed based on risk of six natural hazards—earthquakes, floods, hail, hurricane storm surge, tornadoes and wildfire—using data collected by ATTOM’s neighborhood research portal http://www.homefacts.com/.
ATTOM Data Solutions, the new parent company of RealtyTrac and nation’s leading source for comprehensive housing data, also analyzed home sales and price trends in more than 800 counties with at least 100 single-family home sales in the first six months of 2016. Those 800 counties—which combined have more than 70 million single-family homes and condos—were divided into five equal groups (quintiles) based on the natural hazard risk index and assigned to one of five risk categories: Very High, High, Moderate, Low or Very Low.
“While price and affordability along with access to jobs are the primary drivers in local markets with strong increases in home sales activity in 2016, it’s evident from this data that natural hazard risk does make a difference to homebuyers and investors who are active in this housing market,” said Daren Blomquist, senior vice president at ATTOM Data Solutions. “Even among the subset of counties where the median price is below the national median as well as among the subset of counties where home prices are still affordable for average wage earners, there is a consistent trend of stronger increases in home sales volume compared to a year ago in the lowest-risk markets for natural hazards compared to the highest-risk markets.”

Home values and home prices lower in lowest-risk counties
In the 161 counties in the top quintile for natural hazard risk (Very High Risk), there were 21 million single-family homes and condos representing 30 percent of all homes and condos in the 804 counties analyzed. In the 161 counties in the bottom quintile for natural hazard risk (Very Low Risk) there were 10 million single-family homes and condos representing 15 percent of all homes in the 804 counties analyzed.
The average estimated market value for homes in the lowest-risk counties was $187,291—33 percent below the average estimated market value for homes in the highest-risk counties: $279,570.
The median sales price of single-family homes and condos sold between January and June 2016 in the lowest-risk counties was $156,245 on average, 39 percent below the median sales price in the highest-risk counties during the same time period: $255,160.

Home sales and price trends by type of natural hazard risk
Over the past five years, increases in home sales volume has fallen below the overall national average in counties with the highest risk of earthquakes, hurricane storm surge, wildfires and floods, while counties with the lowest risk for those natural hazards have seen home sales volume increase at a faster pace than the national average over the past five years.
Conversely, home sales activity over the past five years has been stronger than the national average in markets with the highest risk of tornadoes and hail while markets with the lowest risk for those natural hazards have seen below-average increases in home sales activity.

Index Methodology
For its third annual Natural Hazard Housing Index, ATTOM Data Solutions indexed more than 3,000 U.S. counties based on risk of six natural disasters: earthquakes, floods, hail, hurricane storm surge, tornadoes and wildfires. ATTOM also analyzed home sales and price trends in more than 800 counties with at least 100 single-family home sales in the first six months of 2016.
A risk index with a max score of 60 was created for each of the six natural hazards in the 3,111 counties with natural hazard data available. Each natural hazard index was divided into five categories of risk: Very High, High, Moderate, Low and Very Low, based on a severity scale. Those six natural hazard indexes were summed to create a Total Natural Hazard Index with a maximum possible score of 360. For the home sales and price trends analysis, the indexes in 804 counties with sufficient home sales and price data available were split into five equal groups (quintiles) matching the aforementioned five categories of risk.
Flood zone data is based on flood zones created by the Federal Emergency Management Agency (FEMA), and the level of risk was based on the percentage of homes in each county located in high-risk flood zones: A, A99, AE, AH, AO, V, and VE.
Earthquake data is from the United States Geological Survey (USGS), and the level of risk was based on the probability of a magnitude 5.0 earthquake in each county.
Tornado data is from the National Oceanic and Atmospheric Administration (NOAA), and level of risk was based on the Destruction Potential Index (DPI) for each county. DPI is calculated using number of tornados, path of tornados in square miles and intensity of tornados on the Fujita scale (FO to F5).
Wildfire data is from the United States Department of Agriculture Forest Service and Fire Modeling Institute, and risk level is based on the percentage of homes in each county located in “Very High” or “High” Wildfire Hazard Potential (WHP) areas.
Hurricane storm surge data is from FEMA and the National Hurricane Center (NHC), and risk level is based on two factors with equal weight: number and intensity of hurricane strikes historically; and percentage of homes located in flood zones identified as having a risk of “storm-induced waves”: V and VE.
Hail data is from NOAA, and the risk level is based on the average number of hail storms per year in each county with hail that exceeds 1-inch in size over the past 15 years.
