Heat kills 9,000 Americans each year as mobile home residents face heightened risks

Around 9,000 Americans die annually from heat-related causes, five times official figures, according to NPR reporting.

The short version

  • A joint investigation by NPR and Boston University indicates that about 9,000 Americans die annually from heat-related causes, far exceeding federal data.[NPR]
  • Mobile home occupants face elevated hazards, with research showing Maricopa County mobile home residents are six to eight times more likely to die from heat than occupants of standard homes.[NPR]
  • Aging housing contributes to vulnerabilities, as more than one-third of manufactured homes in Arizona's Pima County were built before 1976 federal building code revisions.[NPR]

Key facts

  • An analysis from NPR and Boston University found that approximately 9,000 people in the United States die from heat-related causes each year, surpassing federal statistics by more than fivefold.[NPR]
  • Mobile home residents in Maricopa County, Arizona, face a heat-related fatality rate six to eight times higher than people living in traditional housing.[NPR]
  • Manufactured homes account for roughly 10% of housing in Pima County, Arizona, and over one-third of those residences were built before stricter 1976 federal building codes.[NPR]
  • Sheri Petty died at age 76 following heatstroke-induced cardiac arrest in Tucson after her body temperature reached 106 degrees.[NPR]

What remains uncertain

  • The disparity between the estimated 9,000 annual heat deaths and lower official federal death records reflects unresolved gaps in how heat fatalities are formally tracked and certified.[NPR]
