What’s Driving the Longevity Gap

The decline in U.S. life expectancy is unlike anything we’ve seen  

Bombshell headlines like this popped up in major news outlets last November after the government reported that life expectancy in 2017 fell for the third year in a row.

This is a troubling break from the steady improvements in lifespans since 1900, which were powered by a combination of medical breakthroughs and healthcare policy. Early in the 20th century, antibiotics dramatically increased infant lifespans. Later, new treatments like statins and stents, as well as expanded access to healthcare through Medicare and Medicaid, increased life expectancy across the age range.

But there’s another story behind this story: life expectancy very much depends on where one falls on the economic ladder.

Between 1979 and 2011 – prior to the very recent fall in longevity – the increase in lifespans was much larger for more educated, higher-earning Americans than the gains for people with less education and lower incomes, according to a study by the Center for Retirement Research (CRR).

Smoking is an important factor in this socioeconomic divide. The decline in smoking and cardiovascular disease greatly contributed to rising longevity in the latter half of the 20th century. But while all Americans are smoking less today, those in lower socioeconomic groups still smoke much more. Today, one in four of them is a smoker, compared with just one smoker for every 10 people who attended college, the CRR found.

Looking ahead, education will remain a clear dividing line, and life expectancy will continue to depend crucially on the future prevalence and impact of smoking, as well as obesity, CRR predicted. …Learn More

Why are White Americans’ Deaths Rising?

Rarely does academic research make a splash with the general public like this did. A grim 2015 study, prominently displayed in The New York Times, showed death rates increasing among middle-aged white Americans and blamed so-called “deaths of despair” like opioid addiction, suicide, and liver disease.

Rising mortality, especially for white people with low levels of education, ran counter to the falling death rates the researchers found for Hispanic and black Americans. The husband and wife team who did the study proposed that “economic insecurity” might be an avenue for research into the root cause of white Americans’ deaths of despair.

A 2018 study took up where they left off and found a connection between economic conditions and some types of deaths. Researchers from the University of Michigan, Claremont Graduate University, and the Urban Institute said poor economic conditions – in the form of local employment losses – have played a role in the rising deaths since 1990 from chronic health problems like cardiovascular disease, particularly among 45 to 54 year olds with a high school education or less. However, they could not establish a connection to the rise in deaths of despair.

In a 2019 study in the Journal of Health and Social Behavior, these same researchers instead focused on what is driving the growing educational disparity in life expectancy trends among whites: life expectancy is rising for those with more education but stagnating or falling for less-educated whites.

As for the health reasons behind this, they found that chronic conditions like cardiovascular disease and even cancer are critical to explaining less-educated whites’ life expectancy, and they warned against putting too much emphasis on deaths of despair. In the medical literature, they noted, cardiovascular disease, and some cancers are consistently linked to the “wear and tear” on the body’s systems due to the stress that disadvantaged Americans experience over decades, because they earn less and face adversities ranging from a lack of opportunities and inadequate medical care to substandard living environments. …Learn More
