The new dashboard underscores the disproportionate impact of heat on vulnerable populations, including older adults, outdoor workers, and those without access to air conditioning. Black residents in Los Angeles County face higher fatality rates from heat-related illnesses, and regions like the San Fernando and San Gabriel Valleys are particularly at risk due to a combination of high temperatures and social vulnerabilities. Heat-related illnesses often exacerbate preexisting conditions, such as heart or respiratory diseases, which may go underreported. The tool aims to address these disparities by providing actionable data to inform public health strategies.
