The US is an outlier in high spending on healthcare, as this chart shows.

But compared with similar high-income countries, it’s also unusual in lacking universal health insurance. This + high costs means people seek care later in a disease, hence more premature death.

Why do more young people die young in the US? Chronic diseases are one big driver of premature deaths in 15-49 year olds, as shown here. Obesity is a big driver.

But what really sets the US apart is high death rates from drug abuse, car accidents and suicide / homicide (largely by guns).

The US has higher death rates than comparable rich countries in most age groups, but the biggest difference is in young adults.

Young deaths drag down life expectancy more than older ones.

US life expectancy at birth (78.4 years) is 4 years shorter than the average of 11 comparably large, wealthy countries.

Life expectancy plateaued around 2010, and COVID widened the gap.
