Life expectancy dropped in 2020 by nearly two years across the US, mostly due to Covid-19 and drug overdoses, according to new data released by the Centers for Disease Control and Prevention (CDC).

The CDC's National Center for Health Statistics on Tuesday released its annual report looking at mortality in the US which analyzed death data in all 50 states and the District of Columbia (D.C.) for 2020, the last year for which information is available, reports DPA news agency.

Results found that from 2019 to 2020, life expectancy in the nation declined from 0.2 to three years across all states and D.C.

Overall, life expectancy in the US in 2020 was 77 years, a decline of 1.8 years from 2019.

The states with the greatest decreases include those in the Southwest and US-Mexico border area -- Arizona, New Mexico, and Texas -- as well as Louisiana, Mississippi, Illinois, New York, New Jersey, as well as D.C.

The lowest decline in life expectancy was registered in nearly all New England states, except for Connecticut, as well as Minnesota, Oregon, Washington, Idaho, Utah, Wyoming, Alaska, and Hawaii.

According to the CDC, that number was mostly driven by Covid-19 and "increases in unintentional injuries", such as drug overdose deaths.

Mississippi had the lowest life expectancy (71.9 years) in the nation in 2020, according to the report, while Hawaii had the highest in the country, at 80.7 years.

Hawaii also had the lowest decline in life expectancy, just 0.2 years, while New York state saw the biggest decrease, dropping three years in 2020.

The report also looked at how the data relates to gender.

It found that life expectancy at birth was higher for females in all states and D.C.

The highest difference in life expectancy between females and males was seven years in D.C The lowest was found in Utah, at 3.9 years.

Overall, the male-female difference averaged 5.7 years across the US.
