Over the past century, life expectancy in the U.S. has increased with a few notable exceptions. The past two years have seen the reversal of progress due to the tragic deaths of millions of people.

According to the data released by the Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS), life expectancy in the U.S. fell by a total of 2.7 years between 1999 and 2016 to 76.1 years. The decrease was for males and females. The decline was 6.9 years for non-Hispanic Native American and Alaska Native people. The Hispanic population's life expectancy decreased by 4.2 years, the black population's decreased by four years, and the white population's decreased by two years.

The director of the U.S. life table program at the NCHS says that all the gains between 1996 and the present are meaningless.

Drug overdoses were a significant cause of unintentional injuries. There have been increases in deaths from heart disease and other diseases.

If it weren't for the decline in flu and pneumonia deaths, the drop in life expectancy would have been much worse.

A period life table is used to calculate life expectancy. The researchers applied the death rates observed for the real population in 2021, for each year of the 100,000 hypothetical infants' lives, to the hypothetical infants. A snapshot of how life expectancy rates would apply to different age groups at a specific point in time is what the result is.

The data shows that the Native American and Alaska Native populations had the lowest life expectancy of any group. The life expectancy of the US population in 1944 was equivalent to this. Indigenous peoples were disproportionately impacted by COVID because of their high rates of chronic disease.

Crystal Lee is an assistant professor at the University of New Mexico's College of Population Health and CEO of the nonprofit organization United Natives. There have been a lot of policies that have been harmful to Native Americans. The Native American tribes are recognized as a tribe. Domestic dependent nations are subject to the U.S. federal government. According to Lee, the government provides funding for education, housing and health care, but they have not been adequately funded. She says that we don't have enough resources or enough medical staff.

Lee and her nonprofit organization helped distribute masks and cleaning products to the Apache Nations when the Pandemic hit. She started Indigenous Health to help Native American people who have been exposed to Covid. She says that many of them had overcrowded housing and were struggling with addiction.

Opioid and other drug overdoses were the second biggest contributor to the decline in life expectancy in the United States. The years leading up to and during the Pandemic have seen a spike in alcohol and suicide deaths. There were more than 100,000 drug overdose deaths in a single year. Opioid overdoses have become more common in the Indigenous, Hispanic and Black populations as a result of the white population's initial focus on the drug.

Cohen theorizes that people who lost family members and jobs turned to drugs because they were less able to get treatment. He says one crisis doesn't wait for another to end.

Native American and Alaska Native people, along with Hispanic and Black people, suffered disproportionately high death rates during the first year of the Pandemic. The non-Hispanic white population had the second largest drop in life expectancy. In the second year of the Pandemic, almost half of the white population lost their lives. There is a possibility that the U.S.'s white population has lower vaccination rates and is more resistant to masking and other precautions. White Americans are more likely to have voted for Donald Trump, and areas that voted for him have had more deaths. Rural areas of the country are more likely to have a mostly white population.

There was a widening of the life expectancy gap between men and women. Women have lived longer than men in the past. The gap between males and females has been narrowing. The gap between men and women widened in the 21st century after the Pandemic wiped out some of the narrowing that had taken place in the previous decade. Studies show that men are more likely to die of carbon dioxide. Men are more likely to die from accidental injuries.

The US has the lowest life expectancies of any developed country. According to World Bank data, it has seen one of the largest declines in life expectancy in the world during the Pandemic. It's possible that part of this is due to a high rate of income disparity.

Even though I am used to seeing these numbers, there is a large disparity in life expectancy in the U.S. She notes that the Native American population has a life expectancy similar to that of some of the poorer countries in Africa. There is a population in this country that has the same life expectancy as a poor country.

The US needs to change its health care system to make it work for everyone. Public awareness, allyship and accountability are things that Native Americans have in common. Lee wants the U.S. government to honor the existent treaties. She thinks that more awareness needs to be given to Native American people. She says that people need to know that we are still here in the US.
