Explaining the widening divides in us midlife mortality: Is there a smoking gun?
- bikenaga 10mo ago"Abstract. The education-mortality gradient has increased sharply in the last three decades, with the life-expectancy gap between people with and without a college degree widening from 2.6 years in 1992 to 6.3 years in 2019 (Case and Deaton 2023). During the same period, mortality inequality across counties rose 30 percent, accompanied by an increasing rural health penalty. Using county- and state-level data from the 1992–2019 period, we demonstrate that these three trends arose due to a fundamental shift in the geographic patterns of mortality among college and non-college populations. First, we find a sharp decline in both mortality rates and geographic inequality for college graduates. Second, the reverse was true for people without a college degree; spatial inequality became amplified. Third, we find that rates of smoking play a key role in explaining all three empirical puzzles, with secondary roles attributed to income, other health behaviors, and state policies. Less well-understood is why 'place effects' matter so much for smoking (and mortality) for those without a college degree."
- jncfhnb 10mo agoSeems dubious to me that smoking explains any of these things. I would guess just a cultural cofounder. Obesity and fentanyl would be my guess.
- skybrian 10mo agoSmoking is a major health risk, so it makes sense to me that it's a major factor. Not sure why you'd want to remove it as a confounder.
- halayli 10mo agoI think parent comment was pointing to lack of establishing a causation link. The finding in their abstract is extrapolated by statistical inference. For example smokers tend to drink more etc. The paper does take such factors into account. Personally I wouldn't jump to such a strong conclusion from statistical inference because it closes the door on other factors that might be even stronger when combined together. The paper reflects motivated reasoning more than a discovery outcome. That said, smoking is of course a major health risk, I am just pointing at the research approach.
- eru 10mo agoSmoking is a major health issue, but it's barely a driver of midlife mortality. Smoking tends to kill you later.
- eru 10mo agoSmoking is bad for you, but it's unlikely to kill you in midlife.
- skybrian 10mo agoIn the paper they claim it matters for midlife mortality too: > People who start smoking at age 18 begin to exhibit higher mortality several decades later, with particularly large effects beginning at ages 45–64 (Lawton et al. 2025). A health-capital model allows the mortality rates of older persons to be determined not only by their current smoking behavior but also by smoking in earlier years. In the United States, smoking rates started falling for college graduates earlier than they did for the non-college population. ... > [...] with rapidly improving treatments and screening for lung cancer (Howladeret al. 2020), the major impact of smoking over the longer-term—particularly for people aged 55–64 arises from other more-common tobacco-related diseases such as chronic obstructive pulmonary disease (COPD); cardiovascular diseases such as strokes, aneurysms, and heart attacks; diabetes; and other types of cancers (Carter et al. 2015). Perhaps more surprising is that past county-level smoking rates are highly predictive of deaths of despair. This finding, however, is consistent with an emerging literature in biology that points to a causal influence of smoking on drug addiction [...]
- kevin_thibedeau 10mo agoIt is associated with other adverse behaviors like a sedentary lifestyle. Smokers aren't generally athletically motivated.
- atmavatar 10mo agoWhen my city banned public smoking, there was an immediate and statistically significant decrease in heart attacks and strokes.
- hunterpayne 10mo agoBut probably not for the reason you think.
- mtVessel 10mo agoWhat was the reason?
- braingravy 10mo agoYeah it seems silly. Why is college the primary group factor…? Is there some sort of health effect of sitting college classrooms for 5 years? Seems unlikely. College education is highly associated and predicted by income/access to wealth. Wealth inequality seems like a more likely explanation. Not seeing how they controlled for that across college vs non-college groups.
- bikenaga 10mo agoActually, later in their paper they say: "Although we have argued for a causal role for smoking in generating these patterns, the growing mortality gaps still seem too large and the causes of death too varied to blame the patterns on the adverse health effects of tobacco use alone. As noted above, smoking is likely to play a role in amplifying the impact of other factors adversely affecting midlife mortality, such as the marketing efforts by opioid manufacturers targeted to areas with high rates of smoking-related illness, coupled with epigenetic changes making smokers more susceptible to opioid use disorders. Still, the strength of our findings that smoking is predictive of spatial trends in midlife mortality points towards different mechanisms needed to explain the troubling trends that have unfolded since 1990."
- jncfhnb 10mo ago> manufacturers targeted to areas with high rates of smoking-related illness Oof > epigenetic changes making smokers more susceptible to opioid use disorders This one seems… a bit mystic to me. I would have been much quicker to suggest that a psychological propensity to start smoking mirrors a propensity to start using other drugs vs. arguing for emergent effects of cellular behavior.
- newspaper1 10mo agoIf you have a college degree, you might be able to work from home and not take your life in your hands twice a day on a freeway of death. If you don't have a college degree, you probably have to commute. If you live in a rural area you probably have to commute long distances, with low lighting on potentially icy and twisty single lane roads with oncoming traffic. In all the discussions of RTO vs WFH you almost never see safety mentioned, but it's an incredible upside to not having to drive to and from work every day.
- Sl1mb0 10mo agoThere is also the added stress of commuting, which its fair to assume has negative impacts on heart, cognitive, etc. health.
- BirAdam 10mo agoStress, risk, and stress compounding risk. So many people speed recklessly after having been stuck in traffic. I would, however, not strongly link WFH to college and RTO to non-college. Many companies (as well as governments) have implemented RTO. The key outlier for WFH seems to be contracts and/or good negotiation skills.
- venturecruelty 10mo agoNot that America's car culture isn't a dangerous problem, but I'm pretty sure highway deaths don't explain this...
- hn_acc1 10mo agoAgreed (without regard to applicability of this article) - I was hit twice (i.e. other cars running into mine, their fault) within a calendar year after 5 day RTO went into effect in mid 2024 at work here (the valley).
- ajross 10mo agoI don't buy it. Road fatalities are probably the single easiest hypothesis to isolate. You can't put a label on a cancer or heart attack death, but you sure can for trauma deaths.
- carabiner 10mo agoK-shaped growth, dual economy, permanent underclass what ever you want to call it, shapes all aspects of life.
- venturecruelty 10mo agoCall it what it actually is: societal abuse from wealthy oligarchs with their masks removed. One man bought up all the RAM on planet Earth, and everyone's like "lol I guess computers are just expensive now".
- casey2 10mo agoFor Second-Handers the value of DRAM collapses past 256K anyway. I'd rather the people who can actually use it get societies resources than bums who use it to play games and crap out dumb scribbles or "vfx" Second-Handers love to denigrate the work of Elon Musk and Sam Altman, but these men are solving fundamental problems, you can get your DRAM on the second-hand market after Sam uses it to create AGI. A reasonable man would be very grateful for the existence of these oligarchs. I assume you are just posting unconsciously not unreasonably.
- tdeck 10mo agoIt's been a while since I thought about Poe's Law. Thanks for the laugh.
- hackable_sand 10mo agoYou almost had me there lol
- spangry 10mo agoAs I understand the data in this article, midlife mortality rates for those who hold college degrees has declined from 1992 to 2019, whereas the rate has remained largely stable for non-college degree holders. I wonder if this trend is due, in part, to college degree holders becoming disproportionately female over time, and women having lower midlife mortality rates? https://www.aei.org/wp-content/uploads/2018/05/degrees-1.png https://www.aei.org/wp-content/uploads/2018/05/degrees-1.png
- gbear605 10mo agoGiven that Americans with and without college degrees are split pretty much 50/50, then we’d expect there to be an equal increase in non-college degrees holder mortality rates if this was caused by changing who got degrees. I suppose it’s possible that the gender ratio change is the cause of half of the mortality decrease, and the other half is a broad decrease in mortality rates. That would cause it to cancel out in non-college degrees holder mortality holders and double in college degree holders.
- drillsteps5 10mo agoWomen have had higher life expectancy and lower mortality rate in a number of age brackets, including the one studied in the paper, for much of recorded history, at least in the US. So if more women graduate from college you would expect to see some decrease in average mortality rates (and eventually increase in average life expectancy) among college graduates simply because of that. Kinda like Bill Gates walking into a bar causes bar patron's average net worth jump up a few million. Funny thing, statistics.
- eru 10mo agoNot just more female, but also a broader proportion of the population in total. You'd need to control for these effects to draw any conclusions at all.
- Nifty3929 10mo agoIt's exactly these kind of issues with statistics that cause us all kinds of problems. I'm glad you pointed this one out. It reminds me of a YT video I was watching with similar issues about cancer mortality rates. We've been doing all these treatments, and cancer survival rates have been going up. So everybody cheers about how good the treatments are. But when you control for the fact that earlier detection puts more people into the 'cancer' category earlier, causing 'cancer' people to live statistically longer from diagnosis, then the benefits of the treatments mostly go away (for many but not all types of cancer). And these kinds of misleading issues are all throughout statistics. See Simpson's paradox, etc.
- kazinator 10mo ago> Less well-understood is why “place effects” matter so much for smoking (and mortality) for those without a college degree. Let me take a crack at it: people with college degrees tend to be found in populous places and spaces where smoking is prohibited. Plus, social pressure; lighting up a cigarette in certain company is almost like hurling a racist insult. Just to get through college with a cigarette habit would have been a pain in the ass. You can't be darting outside N times during lectures or exams to have a smoke. If you can even do that; a lot of colleges nowadays have even outdoor smoking bans, no? That's sort of a place effect: college graduates spend a bunch of time in certain places where smoking would have been inconvenient to the point of making some people quit.
- pdonis 10mo agoYour argument as it stands would explain why people with college degrees smoke a lot less than people without them. But that's not what the "place effects" is in the article. "Place effects" is the fact that, if we just look at non-college-graduates, the ones who live in rural areas smoke more and have lower life expectancy than the ones who live in urban areas. The latter effect, I think, can be explained by an argument that's similar to yours: even for non-college graduates, it's a lot more inconvenient to be a smoker in urban areas than in rural areas. You're much more likely to find smoking banned inside the places you go, and to face social disapproval if you try to smoke outdoors in public spaces.
- jjmarr 10mo agoI went to a school in downtown Toronto and we had 10 minute breaks every hour in lectures. I also knew a ton of classmates who smoked. Starting to wonder if the two are correlated.
- hecanjog 10mo agoWhat eras? I went to college in a non-populous place circa ~2001-2005 and in our state smoking bans were just starting to roll out then. Smoking was an everyone thing, and it was normal to go to smokey places on a regular basis even if you didn't smoke. That was nuts and bad of course, but it was normalized.

- sb057 10mo agoFrom a layman's perspective, it seems like it's mostly an expected outcome of college degrees becoming a class signifier. In 1990, only a fifth of American adults had bachelor's degrees, with those who held them making 70% more than high school graduates. A sizeable gap, sure, but those non-college graduates have minimum wage retail workers and general laborers, and union steel and auto workers in the same educational bucket. By 2020, it had risen to well over a third of Americans who had bachelor's, and 105% more income for those with them. One might expect a dilution in a degree's value, but I think it's just a matter of minimum wage workers still being high school graduates, whereas virtually all professional workers (including the increasingly few manufacturing workers) needing a bachelor's to get past the first stage of HR.

- asdff 10mo ago10% increase is a lot lower than I anticipated what with all the talk about a B.S. being the barrier for entry these days.
- tobyjsullivan 10mo ago20% to 33% is not a 10% increase, if that’s what you’re referring to. That’s a 65% increase.
- Spartan-S63 10mo agoEven still, over more than two decades, only a ten percentage point increase is still somewhat mind-blowing. As someone who grew up upper middle class in a wealthier suburban area, I lived in a bubble where the vast majority of people I went to high school with went off to college and got bachelors degrees. To me, it seemed that that was the norm for most Americans, but that's far from reality.

- neuroelectron 10mo agoBoomers need to be kept unaware of how everything is changing for the worse or they might vote differently
- black_13 10mo ago[dead]
- anArbitraryOne 10mo agoSo it's basically saying that smoking is a proximal cause of mortality, and locale is a distal cause of smoking, intensified by not having a college degree?
- Alive-in-2025 10mo agoIt's access to good health in midlife. I know people who have tests, good healthcare, I can afford it, both with time off and with my healthcare coverage itself and the cost of other optional tests.
- WarOnPrivacy 10mo agoI'm one of the millions of Americans in the other group. If I get a treatable, life threatening disorder, I die. We don't get a lot of press. During the first decade of the ACA we didn't exist for anyone reporting on the US healthcare system. But our visibility has improved and some days we're almost noticed for moments at a time.
- Alive-in-2025 10mo agoWe need to fix this problem and provide great health care to all. Half the country seems to think it's some kind of impossible communism country destroying things to give everyone good health care like every other developed country. How can it be that Republicans keep convincing their voters if this? Raise taxes a little on the wealthy, go to single payer
- hattmall 10mo agoIt's a hard sell because most self employed and middle income people actually had reasonable insurance and then the ACA completely screwed them. Sure single payer and universal coverage would be great but how could you trust Democrats to do it when the last healthcare bill was basically one of the worst things to ever happen to the country. ~95% of people that don't work for insurance companies would be better off under the previous system. Just expand Medicaid to include people unable to get insurance due to pre-existing conditions and eliminate coverage maximums, or just say anything over 2 million in a year goes through Medicaid. The ACA is just a huge transfer of tax payer money to insurance companies.

- lucas_membrane 10mo agoCompare the causes of death in midlife now with the causes of death in midlife 50,000 years ago. What is total over all causes of the lesser of the % of deaths by that cause 50,000 years ago and the % of deaths by that cause now? My guess is that total overlap is way less than half. So the things that kill us are mostly modern. The things that we evolved to survive are mostly ancient. And we are a species controlled by the brain, mostly by the subconscious brain, which is basically a collection of ancient survival mechanisms and ancient survival inhibitions. Our brains are proud of removing us from our roots and strive to accelerate our separation from what we are prepared to deal with, which introduces just a few changes that appear to our conscious brains easy enough to mitigate in the long run. But our brains are much better at handling the short run and are absolutely confounded by choices involving both the long run and short run. IOW, we live by deep myths and the myths are dying.
