Mortality with Meep: Top Causes of Death in the United States in 2020
Plus: the mysterious drop in suicides
Before I begin, let meĀ remind you of my post from October 2020:
Even if all theĀ COVIDĀ deaths stop now (they wonāt), it looks likeĀ COVIDĀ will be #3 on the cause of death list for the U.S. in 2020, after cancer and heart disease.
Yes, cancer and heart disease will still outstripĀ COVIDĀ deaths in number.
AndĀ letās take a look as to how that shook out:
Okay,Ā COVIDĀ was #3, and behind heart disease and cancer. But how far behind?
COVID-19 was at 50% of the number of deaths from heart disease, which has been the top killer for years. But note: heart disease deaths were up 5% compared to 2019, while cancer deaths were flat between 2019 and 2020. I find that very interesting.
Indeed, three causes of death in those top ten had increases of 10% or higher:
Diabetes (15% increase)
Unintentional injuries (11% increase)
Alzheimer disease (10% increase)
Of the top ten, two showed decreases:
Suicide (6% decrease)
Chronic lower respiratory disease (3% decrease)
I will address a few of these changes below.
Video review of top causes of death, 2020 and other mortality news
Hereās my video (which I did last week and also posted in myĀ prior post):
Also, Iām trying out doing video round-ups of stories accumulated onĀ Actuarial News. This week I did mortality:

It wonāt necessarily be the same theme each week.
The mysterious drop in suicides
Fox News:Ā US suicides dropped amid coronavirus, defying pandemic expectations
The number of U.S. suicides fell nearly 6% last year amid the coronavirus pandemic ā the largest annual decline in at least four decades, according to preliminary government data.
Death certificates are still coming in and the count could rise. But officials expect a substantial decline will endure, despite worries thatĀ COVID-19 could lead to more suicides.
It is hard to say exactly why suicide deaths dropped so much, but one factor may be a phenomenon seen in the early stages of wars and national disasters, some experts suggested.
āThereās a heroism phase in every disaster period, where weāre banding together and expressing lots of messages of support that weāre in this together,ā said Dr. Christine Moutier, chief medical officer of the American Foundation for Suicide Prevention. āYou saw that, at least in the early months of the pandemic.ā
So, I have some bad news. Because this:
TheĀ CDCĀ has not yet reported national suicide rates for 2020, nor has it provided a breakdown of suicides by state, age or race and ethnicity.
Moutier is anxious to see more data. For example, while overall suicides decreased last year, itās possible that suicides by youths and young adults did not, she said.
I think it will help to look at recent statistics to see how suicides for one group may grow, for another could decrease, and overall it would decrease.
Using theĀ Underlying cause of death database, Iām going to do an age and sex breakout on deaths by suicide.
Here are the absolute counts in 2019:
Youāll see that among adults, the age range with the most suicides are people age 50-55. Thatās due to two things: the number of people in that age range (early Gen X, so tailing off from Boomers) and the rate. For each age group far more males die by suicide than do females.
You can see that deaths by suicide in number drop off in old ageā¦. but thatās because the population is dropping off in size (asĀ mortality rates accelerate at high ages).
If we look at the death rate, we can see the dynamic, which differs by sex:
You can see that deaths by suicide, in rate, is fairly level (and relatively high) for men for most adulthood and increases greatly in old age. Womenās rates peak in late middle age, and then drop off.
At all ages, menās suicide rate is higher than that of women, and past age 50, the disparities in rates are amazingly high. For age 80-84 years, men have a rate over 10 times that of womenā¦ thatās a huge disparity.
Here is one potential explanation for drop in number of suicides: other things were killing off old people more.
You can have the number of deaths by suicide increase for younger people, but if you have just old men dying fromĀ COVIDĀ more (and they are), then that may explain why suicides in total number decreased.
Increase in drug overdoses
The other issue, though, is that deaths by drug overdoses increased a lot in 2020. They are included in unintentional injuries, which includes all sorts of accidents, such as car crashes.
Two items on this out of Actuarial News:
We have the data through the end of August, and it looks really bad.
Synthetic opioid (think fentanyl) overdose deaths were up through the end of August 2020, an increase of 52% for the 12 months ending 8/2020 compared with the 12-month period ending 8/2019. We donāt have detail at that level for the full 2020 yet.
I have a feeling not all of those overdoses were accidental. Coroners may not have been all that interested, in the middle of a pandemic, in investigating whether a drug overdose was accidental or on purpose.
Letās do a comparison, stacking together the āaccidental causesā (including drug overdoses) and suicides.
So yes, we can see āunintentional injuriesā jumped up quite a bit in 2020, but it had been increasing as a cause for some time.
Maybe suicides were down in 2020 in reality, but the age and sex breakout, once we have them, should give us a good idea of how real the change was. If the decrease was among old men (becauseĀ COVIDĀ killed them), we may have our answer. If the decrease was among younger adults, but the drug overdose deaths in that group shot up incrediblyā¦. well, we have a different answer.
Of course, it could be a mixture of those two trends, or something else entirely.
Dead is dead
Yes, Iāve been beating theĀ excess mortality drum for a while nowĀ (and yes, there are multiple ways to define āexcess mortalityā). Maybe I should simply say ātotal mortalityā.
Itās not merely because someĀ COVIDĀ deaths were missed in the first wave of deaths in March/April 2020, though some surely were missed.
Itās that the fact that people are dead is far more important than the specific cause of death.
IĀ mentioned my ādead is deadā perspectiveĀ on a prior post, but this is an important enough point I will keep making it.
Yes, I particularly want to know the demographic breakdown of those who died, especially their age. A lot of people, even those over age 85, died years before they normally would have.Ā Those age 85 have a life expectancy of over 5 years, both male and female, in ānormalā years. Excess mortality, whether directly fromĀ COVIDĀ or effects from lockdowns or other secondary measures, cut that much shorter for many elderly people.
Much younger people also died years before their time, and whether other policies could have reduced the spike in drug overdose deaths in 2020, for instanceā¦ I donāt know. Maybe some areas of the U.S. had a better experience on that score than others, but I do not have the detail breakout on that yet.
We will be arguing the issues for years, and it is best to keep in mind not to focus solely onĀ COVIDĀ deaths, because obviously many causes of death were affected in 2020.
