Map: See how much life expectancy declined in each state in 2020

New York saw the biggest drop in life expectancy from 2019 to 2020: 3 years. Hawaii had the smallest change.

The average life expectancy in the U.S. dropped by nearly two years in 2020, down to 77 years from 78.8 in 2019. It was the country’s lowest average in nearly two decades. 

A new report from the National Center for Health Statistics looks at how that decline varied from state to state. It found that eight states and Washington, D.C., saw life expectancy fall by more than two years from 2019 to 2020. That list includes New Jersey, Texas and Louisiana.

New York saw the sharpest decline: a drop of three years. Hawaii saw the smallest, at just 0.2 years.

Mississippi had the lowest life expectancy in 2020 of any state (71.9 years), while Hawaii had the highest (80.7 years).

Life expectancy is generally used as a proxy for a population’s overall health. The main reason for the decline, of course, was Covid-19, followed by increases in unintentional injuries, mostly from drug overdoses. More than 300,000 people died of Covid-19 in the U.S. in 2020.

Deaths in the U.S. rose 19% from 2019 to 2020 — the largest jump in a century. Life expectancy was lowest in Southern states in 2020, including Alabama, Kentucky, Mississippi, Tennessee and West Virginia. That was most likely due to Covid deaths, according to Dr. Robert Anderson, chief of mortality statistics at NCHS, who reviewed the report.

Anderson said the U.S. has typically seen a gradual trend toward higher life expectancies over time.

"We really haven’t really seen anything like this since the 1918 flu pandemic," he said. At that time, the average life expectancy fell from 50.9 years in 1917 to 39.1 years in 1918, according to Anderson.

The data for 2021, once finalized and broken down by state, is unlikely to look much rosier. 

"Mortality was a little higher in 2021 than in 2020, so we may see some additional declines," Anderson said.

"If Covid magically goes away, then we could see a big rebound," he added. "That said, it’s hard to know what the long-term effects of the disease are going to be."
