Maricopa County Sees Decline in Heat-Related Deaths for 2024

For the first time in a decade, Maricopa County has reported a decrease in heat-related deaths, a significant shift in a concerning trend. In 2024, the county confirmed 602 such fatalities, down from 645 in 2023.

This announcement, made on Monday, marks the first decline since 2014 when deaths attributed to extreme heat first began to rise annually. Nevertheless, eight heat-related deaths from 2024 remain under investigation.

The Board of County Supervisors Chairman, Thomas Galvin, emphasized the importance of continued education regarding the risks associated with extreme heat. “While this reduction is a step in the right direction, we need to continue educating residents about the dangers of extreme heat and the steps they can take to stay safe and protect their loved ones,” he stated.

Despite this encouraging trend, 2024 was marked by extreme temperatures, including a heat wave that saw the Valley experience an unprecedented 113 consecutive days of 100-degree temperatures. Notably, individuals struggling with substance abuse were disproportionately affected, with over 300 deaths associated with such circumstances.

Geographically, about 77% of the heat-related fatalities occurred outdoors, with 66% of those deaths identified within urban areas. Additionally, a preliminary report revealed that while 88% of indoor heat deaths happened where air conditioning was available, 70% of those units were non-functional.

Heat-related deaths are classified as either heat-caused or heat-contributing, with 61% of the fatalities in 2024 categorized as heat-caused, indicating that extreme heat directly led to the deaths.

The figures highlight the ongoing challenges faced by county officials and residents alike as they navigate the ongoing risks of heat exposure, underscoring the need for vigilance and community support in promoting heat safety.
