Stark US mortality trends revealed in 34-year county-level study

A new study has mapped mortality trends across US counties over 34 years. Researchers from the University of Washington tracked death rates for the 21 most common causes from 1980 to 2014. Their findings reveal stark regional differences in how and why Americans die. The team analysed county-level data to show shifts in life expectancy and causes of death. While average life spans have grown since 1980, some areas face worsening outcomes. Color-coded maps highlight where mortality rates for specific causes have risen or fallen.

Deaths linked to alcohol, drugs, and mental health disorders have climbed sharply in many regions. The maps also display percentage changes in mortality rates since 1980 for each cause. Certain counties now bear a heavier burden from these conditions than others. The study provides a detailed view of how mortality patterns vary across the country. It shows where progress has been made and where specific health challenges persist. Public health officials can use these maps to target resources more effectively.
