A recent study listed Hawaii as the top state in America for the longest average life expectancy. Those living in Hawaii can expect to live to an average of 80.7 years. The Aloha state was the only state to crack the 80-year milestone. The national average life expectancy for men in the U.S. is 73.5 years old, while the average for women is 79.3 years age. Washington State (#2), Minnesota (#3) California (#4-tie), and Massachusetts (#4-tie) rounded out the list, with averages around 79 years old. Life expectancies declined nationwide due to the COVID-19 pandemic, according to the study.
