The place most deaths occurred

Pima County, Arizona’s second most populous county and residential to Tucson, final 12 months began together with heat-related deaths in a brand new on-line dashboard. Maricopa County, house to Phoenix, America’s hottest massive metropolis, for years has tracked heat-related deaths.
