King County Mortality: Trends and Disparities, 2015-2024

This report examines mortality patterns among King County residents from 2015 through 2024, a decade marked by the COVID-19 pandemic, a sustained opioid epidemic, and widening health disparities. It analyzes trends in all-cause and cause-specific death rates and life expectancy across demographic groups and county regions, using death certificate data from the Washington State Department of Health Center for Health Statistics. While 2024 brought encouraging signs — including a 23% drop in opioid overdose deaths and rising life expectancy — disparities by race, ethnicity, region, and sex continued to grow, underscoring the uneven distribution of progress across King County communities.
