Mono County has earned the distinction of having the longest life expectancy in California, with residents living an impressive average of 98.9 years—19 years longer than the state average. This remarkable statistic, highlighted by Stacker, sets Mono County apart as a beacon of longevity in the Golden State.

Stacker's analysis drew from the 2024 County Health Rankings & Roadmaps provided by the University of Wisconsin Population Health Institute. The study measured life expectancy by analyzing mortality data from the National Vital Statistics System, focusing on the average number of years from birth a person can expect to live. Counties with insufficient data were excluded from the analysis.

While the specific factors contributing to Mono County's exceptional life expectancy weren't detailed, it is likely due to a combination of environmental quality, access to healthcare, and an active lifestyle that promotes increased exercise.
