PHOENIX - One year later, the Maricopa County Dept. of Public Health has released their final heat death report for 2021 - and it broke records.
Health officials said 339 people died from heat-related issues in the county last year. This marks the highest number of heat deaths since Maricopa County started recording the data back in 2006.
People are only added to the data after the county medical examiner confirms that heat caused or contributed to their death. Normally, potential heat-related cases are listed as "under investigation."
Here's some key points noted in the report:
- Of those who died, 130 of them were homeless
- Maricopa County residents consisted of 88% of the deaths, and ⅔ of that number had been living in the county for more than 20 years
- 75% of heat-associated deaths happened outside
- For those who died indoors, 88% had an air conditioner. The A/C was not working in 75% of those cases.
- Most heat-related deaths happened in June, July and August, but some occurred as early as April and as late as November
- ⅔ of deaths happened on days without an Excessive Heat Warning
"These data tell us that it’s not just visitors or newer residents who can be severely affected by our hot weather," said Nick Staab, a medical epidemiologist with the Maricopa County Dept. of Public Health in a statement. "Even when we think we’ve gotten used to Arizona summers, we need to take precautions like staying hydrated and avoiding outdoor activity in the hottest part of the day."
