The hazards accounting for most of this area's expected annual loss are inland flooding, cold wave and tornado, with inland flooding alone responsible for 52% of it. Every one of these is independently rated low or minimal nationally — this describes how a small risk is composed, not a large one.

Overall hazard risk is lower than 85% of measured US cities.

Williamson County records 3.7 homicide deaths per 100,000 residents a year, near the middle of counties measured. The CDC does not publish this below county level.

Firearm deaths of all intents run at 12.3 per 100,000 — more than the homicide rate, since the figure counts suicides and accidents as well as homicides.

Drug overdose deaths run at 9.5 per 100,000 residents in Williamson County.

Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides, so the firearm figure and the homicide figure above it count some of the same deaths twice over. They overlap and should not be added together.

Death rates are crude rates — deaths divided by population, not adjusted for age — except where a count was too small for the CDC to publish and it modeled the rate, which the card marks. They come from provisional death certificate records, published by the CDC by county and not below it. So they describe the county around Sonterra (Williamson County) rather than Sonterra itself. They are shown and not scored. How to read death rates.
