Peer-Reviewed Publication

A sweeping 26-country study reveals a consistent gap in trust toward climate scientists based on political ideology, with right-leaning individuals reporting lower trust than their left-leaning counterparts.

New study reveals striking differences in life expectancy across U.S. states

Yale University
Peer-Reviewed Publication

New Haven, Conn. — A sweeping new study led by researchers at the Yale School of Public Health (YSPH) reveals stark disparities in life expectancy across U.S. states and Washington, D.C. over the past century – offering new insights into how a region’s public health policies, social conditions, and environmental factors can shape people’s lifespans.

Analyzing more than 179 million deaths between 1969 and 2020, the multi-institutional research team traced life expectancy trends by birth cohort — a more precise measure for following the life experiences of a population than traditional year-by-year summaries of mortality, which represent a mix of many generations.

The study, which appears in JAMA Network Open, found that some states saw dramatic gains in life expectancy, while others, particularly in the U.S. South, experienced little or no improvement over an entire century.

Matt Boyd of Adapt Research Ltd, New Zealand, and Nick Wilson of the University of Otago, New Zealand, present these findings in the open-access journal PLOS One on May 7, 2025.
