The life expectancy of Americans has fallen in recent years after a long period when it had been increasing. There are a number of factors which contribute to the fall. The Covid pandemic, with over 1m deaths, made a significant impact on lowering the average life expectancy. In comparison with other peer countries, the USA also did not return to pre-Covid levels at the same rate. However there are also other important factors driving this, namely gun deaths and drug deaths as a result of opioid overdoses. And another major contributor to lower life expectancy in the States is inequality in the US healthcare system. In this edition of The Inquiry Tanya Beckett explores why US life expectancy is falling. She hears from Jeremy Ney an adjunct professor at Presidio Graduate School in San Francisco and author of American Inequality, a data project that highlights US inequality and regional divides. Dr. Mark Rosenberg helped set up the Centre for Disease Control’s National Centre for Injury Prevention and Control (NCIPC) and is a key proponent of research that examines how to reduce gun violence. He explains how gun deaths among young people have a big influence on the average life expectancy numbers. Dr. Judith Feinberg, is a professor at West Virginia University School of Medicine - her experience of working with communities with high levels of opioid problems makes her an authority on the extent to which drug overdose deaths impact average life expectancy. Ellen Marra is a professor of health economics at Harvard University - she says that diseases such as cancer and cardio deaths are big factors in lower life expectancy, compared with the number of gun and opioid deaths.
