Life expectancy at birth in the United States has continued to rebound since the COVID-19 pandemic, as new Centers for Disease Control and Prevention data indicates life expectancy in the U.S. in 2023 was near pre-pandemic levels.The updated numbers show U.S. life expectancy at birth increased to 78.4 years as of 2023, which was up from 77.5 in 2022, 76.4 in 2021 and 77 in 2020. The average life expectancy in the U.S. before the pandemic was 78.8 years.One major reason for the rebound in overall life expectancy was the decrease in COVID-19-related deaths in 2022 and 2023 compared to 2020 and 2021. There were also improvements in heart disease, unintentional injuries, cancer, and diabetes-related deaths.RELATED STORY | Will life expectancy ever reach 100?
