Most of the population data in this video comes from the Population Reference Bureau, especially this excellent article: www.prb.org/articles/how-many... That's also where I learned that life expectancy in Iron Age France was 10-12.
The graphs and much of the information on life expectancy at various ages comes from Our World in Data, which is amazing. Here's their article on life expectancy over time and across communities: ourworldindata.org/life-expec...
Their article on child survival and mortality statistics: ourworldindata.org/child-mort...
And their article examining mortality in the distant past: ourworldindata.org/child-mort...
I mostly relied on PRB info for global populations at various times, but this research summary from census.gov was also helpful: www.census.gov/data/tables/ti...
Here's my math for why most people have never been 20: Of the first 100 billion people who lived, at least half (the most prominent researchers in the field consider that estimate on the low end) of people died before 15. Counting the 3% or so who died between 15 and 20, that means that probably at least 53 billion of the first 100 billion people died before the age of 20. Of the most recent 10 billion who died (most of whom were born between 1800 and 1950), over 30% died before the age of 20. That takes us to a conservative estimate of 56 billion of the 110 billion people who've died so far. (2.6 billion people are CURRENTLY under the age of 20, so even if you look at the entire population of humans, it is probable that most people have never been 20--hence the title.)

Heh, you have OCD like me, I couldn’t possibly tell!
I think you’re amazing and that this is amazing, also.
John, did you take the help of the resident mathematician Daniel Biss for this video?
I couldn't find this in the citations but possible I missed it - is there a citation for 1/4 of all humans dying of tuberculosis about 200 years ago? That's wild!
I sometimes have thought as this spectrum in terms of a line of all human lifetimes til now, and I would turn it into a thought examination of aliens with a grab-bag of each person in the line disconnected from the line itself. The aliens, being ignorant of our history, can pull humans at random out and look at all the facts of their life including the spatial ones. So although most often they pull out the thick eras of people from forgotten times who lived free and died young, to find this occasional rare cityslicker, that Samurai, this astronaut, that ancestor on the Moon, on Mars, etc... And I would examine how stunned they would be to have to work back from a long interest in the 'basic human experience' to those rare finds to the idea of a sudden exponential rise in the use of knowledge and technology. But how much observations would they have to make of the bag of how a giant bunch of "killed naked near a redwood" people could eventually make this one shiny spaceperson.
"as much as [20] can suck, it always beats the alternative" feeling grateful to be 20 today, thank you john (and complex healthcare systems) 💛
Well congrats on surviving upto 20 . DFTBA

Crazy stuff. I'm 22 now, 23 in a few months. Feels like I've just gotten used to being over the age of 18. Scary how time seems to accelerate
Yep. I'm 32, now, and it feels like time has sped up so much that I imagine being 70 must make weeks seem to go by in the blink of an eye. I'm a procrastinator, and it's crazy how time just flies by, if I'm not being super intentional about what I need to get done. As an 18 year old, I'd put things off for maybe a week or two, but now, what feels like weeks can actually be 6 months.
I hope you have an amazing birthday and an incredible life!
@@sillyslicker1 Yeah that’s so true, if someone releases a song it feels like it just came out and then I’ll discover that it came out a year ago
Same, I’ll be 23 in March and I feel the same way. It took me until 21 to realize that I am an adult and time does fly by. I didn’t think those four years would come by so fast, but they did.
@@sillyslicker1 thank you, I hope your life goes great also 😁 I think understanding we are going to be reminded of how short out time really is, gives a great motivator to fight procrastination. I am definitely a heavy procrastinator also, thinking about how fast recent months and weeks have gone often give me reason to stop whatever wasteful thing I'm doing. Usually binging CZcams lol
@@georgewashingmachine1 this feeling is a strange one. I remember 10 years ago and seeing 22/23 years old thinking they look like proper adults. Well that's not how I feel, but of course that's still what kids think... and slowly come to realise that most adults of any age often feel exactly the same. We are all kids in adult bodies haha

As a person who’s daughter died at 4 months and mother died at 61, this video kinda gave me some perspective that makes me a splash less miserable somehow. I’m not sure why but I sure am grateful.
Internet hugs to you
I'm sorry for your loss, Raechel, but I'm glad to hear this video gave you some peace.
Wow. What a testimony. Sending love your way...
The human experience can be so cruel and painful- I’m glad the video was able to provide you at least a little bit of comfort. Sending you love 💕
The human experience can be difficult to comprehend at times. Sometimes what we really need to hear is that others have felt what we have and that we aren't alone. I hope you are able to stay strong and move on to a brighter future.
Somehow, as a very soon-to-be 20yr old, this made my "holy shit, I'm not a teenager anymore I'm ancient" life crisis ease up.
I have a genetically rare, medically complex 1-year-old who has a very good chance of living into adulthood. She may even outlive me. I'm so, so thankful we live in a world where she was able to easily get a feeding tube when she stopped taking a bottle and where we only had to drive 30 minutes up the freeway for her heart repair surgery. Without modern medicine, she would've died by her first birthday.
Today is my birthday, I am 35. I am currently pregnant and it probably won't kill me, I am unabashedly grateful for that. I already have a toddler, and I know she is likely to live into adulthood, and I am *extremely* grateful for that.
These kinds of facts of my life are something I want for all humans alive.
I am absolutely grateful to have access to healthcare, but I shouldn't have to be, because there shouldn't be a contrast with living humans who have to worry about medical access. I want to live in a world where it's a fact for everyone.

Happy Birthday 🎂

Wow, I genuinely became happy reading this, thanku
I’m a living example of the child mortality rate going down. At six months I needed life-saving surgery. At age four I contracted meningococcal meningitis and barely made it to the emergency room. Throughout my youth I was hospitalized for asthma. I’m 43 years old today and can only assume if I’d been born a hundred years prior, I’d never have made it to 20. Probably not even close.
holy shit bro that's insane glad you're alright now! modern medicine is insane I can't wait to see what we come up with in 60 years
Sounds like if you were born 50-60 years ago, you wouldn’t live past a year.
You should play the lottery. Like, a lot.
Not to sound like i'm trying to one up you, I am just trying to share. I was positioned horizontal across my mother's tummy when I was still in her womb, instead of the normal vertically upside down position. Without C-section, it would be literally impossible to get me out of her. If we existed a hundred years ago, both I would've never existed and my mother would've died during labor.
Yep. I have 2/5 of my kids that would have certainly died without modern medicine, and at least 1 more without modern antibiotics. I would have died in childbirth three times over, and my father unlikely to be born at all. My husband would have died 2 weeks ago had he not had emergency surgery.
i just turned 27 and I feel like I go thru a midlife crisis every day. Constantly thinking "man, a lot of humans, A LOT, didn't make it this far"
@@bilbobaggins9451 Yeah brother, quarter life crisis are real. I myself will turn 28 in a few months and all I could think about since turning 26 is that I'm closer to being 50 than being born at this point.
sounds about right.
I'm so thankful that I made it past 20. My high-school graduating class of 138 had two people who died in high-school. I was almost a third. Very thankful I wasn't and so grateful for all the help I've had along the way.
As I approach my 64th birthday, your comments give me hope for humanity. Keep being that nice person who loves knowledge. And keep being that knowledgeable person who is nice. Either way, it’s people like you who make the world a better place!
Thanks, Brian! 💛💛 -John
May someone still need you, and someone still feed you, when you're 64.

Happy upcoming birthday
I turn 20 in a week and a half. That was crazy enough, but this weirdly adds a layer of joy on top of it? So thanks for making me feel better about it, John.
Happy Almost Birthday! -John
After your birthday tell everyone you are above average
Hey! Also turning 20 in two weeks
This is my last day of being 20 and this did indeed make me appreciate it more.
I turned 20 last month!
One of my best friends died recently at the age of 20. For some reason, this video brings me a bit of peace. He got something. I’m grateful we live in the world where he had a chance. He was diabetic from birth and likely wouldn’t have even lived a quarter of that length not too long ago. I was born with sleep apnea and a few other issues as well, so I likely would’ve been part of the infant mortality back then as well. In fact, a lot of my friends would have been. This is actually really good for me to know.
In a weird way congratulations to your friend for making the milestone! 🎉🎊🍾I hope you continue to find peace and live your life well.
Having recently turned 21, this really puts into perspective how lucky I am to be alive.
And able to drink legally! 🎉
when I was a small kid I almost died of rotavirus (a common d+v bug we now vaccinate against) luckily I was taken into hospital and rehydrated. but I do sometimes think that for every me that is now living happily and can forget about it, there is another kid who didn't get the health care they deserved, a cool person we never got to have around, and a grieving parent.
Thanks for sharing your experience. I'm really grateful you're here with us. -John
This is why to me it is such a beautiful thing to show signs of aging (grey hair, wrinkles, etc.) It is such a privilege to grow old that so few had before modern history.
It’s now been 10 years since I first heard John’s voice in World History videos in 10th grade. I’m now a lonely structural engineer just grinding away my days. But hearing his voice reminds me of better days when I had dreams for the future! 😊
Don’t stop dreaming about the future just because you’re older! Make some cool plans or go on a trip somewhere! Life is for living, not just for grinding away.
I'm 55 and still dreaming about the future.
Thanks for expanding my perspective, John!!
I never knew the “average age” thing, that’s so crazy and so insightful to how people used to live, I can’t believe I haven’t heard that before
It’s because public education is more interested in getting vague ideas across instead of solidifying your understanding of concepts.
It also isn’t in their interest for you to understand the truth surrounding a statistic. For instance administrations like to allude to an increase in average life expectancy attributed to policy. Or my favorite the unemployment rate vs the labor participation rate. You would assume the unemployment rate accounts for all people without a job, it doesn’t. In fact the official numbers get to cut off large sections of the employable populace. If you haven’t sought employment in the past two years you no longer contribute to the unemployment rate.
The labor participation rate is the statistic that should be used when discussing job numbers but it’s never as pretty of a number.
@@FormerGovernmentHuman Life expectancy is attributed to policy, like giving babies vaccines when they are born, without that we would have average age expentancy of 50
@@lolasdm6959 Vaccines aren’t policy, they’re an invention.

have you never taken a history class? it's common knowledge that most people used to die in childhood. that's why people used to have so many kids bc unfortunately many of them would not survive childhood due to disease and kids were a necessity to running the household especially when it came to farming and providing for themselves. modern medicine hasn't actually been around that long when you consider all the centuries before us
I’m in the final years of my 20s, have struggled with mental illness my whole life & recently developed a love of genealogy & public health. This video is a perfect combination of things I wanted to learn and things I needed to hear. Life is so hard but this was a welcome reminder to cherish it anyways.
I’m in a similar situation. Here’s to our upcoming 30s! Life is hard and still very much worth cherishing.
"You have to be strong. The hardest thing in this world is to live in it. Be brave. Live. For me."
- Buffy Summers.
This line cut me deep and I always think of it when times are tough.
Your comment reminded me of it. I hope it means something good to you, too. 🙂
There's nothing quite like studying ones own genealogy to make one grateful for modern public health measures. Count how many female ancestors you have that died in child birth, or how many male ancestors that married more than twice because their wives kept dying or how many family members died before the age of 5 from preventable diseases. It's disturbing but really really gives me perspective.
I’m 36 and took a NOSE DIVE into genealogy as soon as I hit 30. It’s been such an amazing and healing journey. However as someone without children it also brought me sadness and my very extensive tree will end with my branch!!
You got this. Take 1 step at a time, and then another, and then another. That’s how life works.
A little amusing I got recommended this video again today, on my 20th birthday. Watched it recently and it’s a very good one John
This video was oddly comforting. Im turning 20 in a month, and I find myself anxious. More is to be expected of me, I will be forced to find my role in this world in some capacity, I still feel very young but somehow so old. I used to look at my childhood with a comfortable nostalgia, and now I cling to childhood memories and people in quiet desperation. My 20s represent so much that I feel unequipped to handle. In this next decade it's very likely that I'm going to experience the loss of friends and family members, I will have to become financially literate and stable, my parents will sell my childhood home, my siblings will disperse and our visits will become less frequent. And while I recognize that there will be joy, and laughter, new experiences, freedoms, and wonderful people; all of the unforeseeable happiness pales in comparison to the inevitable loss I will surely encounter. The weight of it all feels unbearable and suffocating at points. Thank you John for a little bit of perspective. It makes me want to keep living when I realize that most of humanity never received this opportunity. Even if I don't yet know what to make of such an opportunity, in some way, just being alive is enough.
Wow, this really puts into perspective the life saving impacts of modern medicine
Indeed. Also public health interventions like clean water, vaccination, and regulation of toxins. Good sewer systems have probably saved more lives than all medicines combined! -John
@@vlogbrothers I mean in a way, all those things you mention are forms of modern "medicine".
My grandmother is a daily reminder of this to me, and to herself. Whilst her mother (my great-grandmother) died at 57, my grandmother will turn 89 soon, albeit having the same health problems as her own mother had. But modern medicine has helped her immensely in having a life more than 1/3 longer than her mother's had been 🤯
I wonder how many lives have been saved by Alexander Cumming's invention of the s-bend toilet pipe
Too bad there’s now a section of society who are against vaccines & Public Health measures who are trying to drag us back to the old times.
Were it not for modern medicine I would have died giving birth to my daughter. She would have died a few minutes later because she couldn’t breathe after my emergency c-section. Now, at 33 with a near 3-year-old, both healthy, I am shaken and grateful for this additional perspective. I’m so grateful for Nerdfighteria and all the work that has been done to support the MCOE. Thank you to everyone here. 💚
What is the MCOE?
I have the same story as OP. I am 36 with a 5 yo, I wouldn't have survived my what was a textbook-case-until-it-suddenly-wasn't childbirth, and neither would my daughter.
Oh and MCOE is Maternal Center of Excellence, PIH.
Same here. My son and I both would have died during pregnancy or during birth. My doctor was a bad ass and now I’m 33 with a 7 year old.
I'm so thankful to modern medicine for allowing you and your baby to live! I hope you both have beautiful lives!
My mother and I would have died as well, and that's assuming my mother lived long enough to have me in the first place.
We are so, so privileged to be able to access modern medicine.
It's been literal years since Crash Course got me through college and here I am again, love the video
Nice insight of humanity in numbers so far... Thanks!
One would think that this level of melancholy and talk about premature death would be depressing but like always you've found the beauty in it John. The humanity of old is probably ecstatic that you have lived long enough to tell us this
Every time this community comes through on another milestoe for MCOE and PIH in general, I'm so delighted. And then I think - what more can we do? I don't mean that in a flippant or dismissive way. I just continue to be so impressed and moved at how we stick together and to, she wrote in slightly poor taste, commit to this bit. Because truly the 'bit' in Nerdfighteria is being awesome. It's seeing that you and Hank have built a boat and we all trust its sea-worthiness so much that we put our hearts and souls on board. No pressure, right? But we're here and learn together what makes a boat, how things float, and how to steer it so that the sails fill and we're away on this amazing journey. I'm so grateful.
Very well said.

I'm not sure how high I thought the child mortality rate was in 2022 but it turns out to be infinity higher than that
As a currently-19-year-old, this makes me feel really grateful for my life and the choice to keep living it. From the title I was also half expecting the video to be about being 20. I think a reflection back on it would be cool, especially since most of Nerdfighteria is past that point in life now

Hamilton said it best: "I never thought I'd live past 20. Where I come from, some get half as many." Having had two near-death experiences before I was 6, I'm very grateful for my almost 29 years.

Lol, I came here to say this.
God i hate that musical lol. But good for you! ^^
@@snakewithapen5489 Why do you hate it? I'm always open to the negative side I might not have spotted in things I like.
@TheDanishGuyReviews It's one of those things that I just Could Not Escape for a solid 3 years at school, and that soured the experience for me. Y'know when something is so popular that everyone is talking about it and singing and quoting the songs, and it's really not your type of interest so you never could get into it but all your friends won't talk about anything else at lunch? Yeah lol.
I tried to watch it relatively recently bc I'd managed to avoid it for like 5 years? And idk if I was just prejudiced or if it really was that bad but man I couldn't stand it. Lin Manuel looked so greasy lmao. And heavy musicals aren't really my type of theater production to begin with, but essentially every single line of dialogue was in a song or a rap.
I also am quite a big history fan and i actually know quite a lot about american history in particular, so I'm a little disappointed that it was never something I liked, but the whole premise of it to me personally seemed so... gross. Making a founding father into a 'sympathetic' and 'hip' character to sing and dance in a play. Turning the other great American history figures who have their real lives very well documented into the same. Like they were real people that you're making into characters... it just came across as kinda weird.
Obviously they had to dramatize it to make a plot, but it just felt so disingenuous. I couldn't get over the incredible cringe that was hearing someone pretending to be THE Alexander Hamilton sing about how his life was so hard lol. I'm all for making history more engaging to a younger audience, but not when you do it like that. It just felt Wrong. Almost revisionist, kind of sleazy, and very historically innacurate. But idk, that's just how I felt about it.
Always interesting, thank you.
Love the work you guys are doing.❤
I turned 20 recently and this brought a lot of pure sadness and pure gratitude to my day today.
When your dog is older than like 25% of humans ever

I wonder how old the average dog was. Of course the statistics aren't going to be as comprehensive as they are for humans, so it's probably impossible to estimate.
@@vigilantcosmicpenguin8721 Yeah me too, but i dont think many romans or whatever would count how long their dog has lived, they probarly dident even know when they were born

Just got this in my recommended on my 20th. Cheers!
Thank you for adding new perspective to my last day of being 20! I already appreciated the last year but this makes me thankful for all of the potential years to come too.
We may be bday twins :) Happy belated birthday and I wish you the best
As someone who has only been 20 for about a week now, I've never been happier to be a statistical anomaly
wow. my mind is completely blown. and you explained it so well I feel like I can actually wrap my head around this. thank you John
Love your videos.... keep up the good work
Thank you for making yet another warmup I can use with my social studies class. Much appreciated
Turned 20 last month. Feeling grateful. Wishing everyone a long life
excellent video, thank you very much
What an odd video to show up on my home page, just so far removed from what I normally watch. But I really needed to hear this… thanks
The puff points to progress. Great video as always.
Honestly, my twenties had their ups and downs. The ups included graduating from college and having my first full time job. The downs included losing two grandparents that I loved dearly as well as being unemployed for way longer than I wanted to and a global pandemic that's still going on. As I write this as a 31 year old person, I have no idea what my thirties will hold, but I hope that it will be productive.
Maybe you'll get on a gameshow
Productive is an interesting choice of words. Regardless, I hope your 30s will be joyful and filled with love.
This is wild. I am 23. Its wild to think im still here- especially since i didn't think id be alive today. I struggled hard in highschool with mental health. It gives me some comfort to know i survived past 20. And im still surviving
I dont know how I got here and I dont know why you have all this information
But I love it!
This is one of my favourite recent Vlogbrothers videos:
It is kinda like classical education: it starts with the grammar, with teaching facts; then the logic, explaining what is gong on; then with the rhetoric, the explanation of why it is important.
BUT best yet, it gives an action point, working to collaborate to decrease mortality.
A freshman on my campus passed away just after I first watched this a week ago. Scarily coincidental timing, and a rough week for many at my university.
It’s odd to see things from such a statistical standpoint. Wanted to come back and say thank you
dude u have an interesting perspective on things
the real question is, what percentage of all the people who had ever lived had watched the vlogbrothers?
uh oh i feel a rabbithole coming on..... -John
never enough
@@vlogbrothers Which I immediately went down. I obviously do not know the answer, but I can give an upper and a lower bound: vlogbrothers has about 3.5 million subscribers, and just over 906 million views. At minimum, 3.5 million (out of 110 billion) humans have watched the vlogbrothers, at maximum 906 million (on the unrealistic assumption that each view was a unique person).
Therefore, between 0.003% (subscribers only) and about 0.84% (each view is a unique person) are the absolute upper and lower bounds. Neither of which is realistic.
I can think of two ways to estimate the real-person counts, though I do not have enough viewer statistics (Hank and John might) to use for this: 1. Make an assumption as to the number of views by the *average* vlogbrother viewer, divide 906 million by that. 2. Or make an assumption as to the share of viewers who subscribe.
I would estimate the first number to be between 20 and 50. Many people (like me) watched a lot more than that, but many other people might only have seen one or two. This would mean somewhere between 18 and 45 million people. My estimate for the viewers vs subscribers would be a factor of 5-10, i.e. one in every 5 to 10 people who watch vlogbrothers videos subscribe to the channel. This would result in almost the same range of numbers, only slightly lower.
If I am reasonably close to the mark, these numbers would mean between 0.015% and 0.041% of all humans who ever lived have seen at least one vlogbrothers video.
This is one of my favorite Vlogbrothers videos of all time (and I've watched *all* of them since becoming a Nerdfighter at the beginning of the pandemic). At once informative, reflective, and also hopeful. Ya'll are dope and It's a joy to be a part of this community and make collective (and important!) change in the world. Excited for the MCOE and PIH!
Welcome to the community!
omg nerdfighters is still a thing? I joined the website in junior-high like 15 years ago and haven't really looked for it since then. It's amazing they kept that thing going for so long.
I'm 22 and spent most of the last decade in the same building. . . I feel like I wasted so much time, but I'm glad I made it this far.
This was great 👍
I didn't know where this was going, I found it interesting, and then by the end of the epi. I had tears in my eyes. I don't have a lot but I whole heartedly support pih with what I can.
I'm 43, Swede and happy I live in a country and time where modern medicine saves lives. Just 50 years ago I would not have survied childbirth. Neither of us would have survived. Progress and human ingenuity is a wonderous thing. It makes me glad that not just we in the west get to see decreased numbers of child mortality.
I want more of this!
Thank you my friend. Interesting.
This is not quite the break from statistics homework I was hoping for, but it was certainly interesting!
Wow.
Thanks for bending my brain again and putting a thing in perspective that I'd not previously contemplated.
I became a grandmother about 10 months ago and once again, my perspective on life shifted. Your video triggered another thought stream. As parent, the most painful occurrence I could imagine was the death of one of my children. That changed for me when my 1st grandbaby was born. Now the most painful thing imaginable is having to support my daughter through the death of her child.
Even though the death of children was previously common, even frequent, I can't imagine that it was any less painful to the parents. Or maybe they just expected it? How different the lives of parents must have been if the next accident of some sort or the next illness could mean the end of a short life. I can't help wonder what the daily thoughts of parents- and even the children themselves- were.
I'm thankful to be fortunate enough to live in a time when my children are expected to outlive me. My ancestors have, once again, gained respect for their endurance.
I made it!
Going on 21 now, and I'm very appreciative to be here. Stay well out there, everyone!
It's like I tell my kids; "Statistically, Everything Important Happened Before You Were Born"
I've made peace with how I'm going to die.
Happy Tuesday, Rocco
John and Hank are such unique creators on the internet. There are few creators with their longevity, success and thoughtfulness. You guys feel like my friends and teachers. Thank you both for inspiring us for all these years!
Yeah yeah yeah! Nice work!
John always finds a way to make me cry, especially since I just read part of William shatners recount of his time in space and how to him it felt like a funeral.
Once again, love to see your tiktoks get flashed out into vlogbrother videos, I feel like I got a sneak peak on what’s to come lol
You just blew my mind.
This is the kind of content CZcams needs.
it's my 20th birthday today, ironically. twas filled with dread and denial all day, but after watching this i'm also filled with a lot more gratitude. thanks john :)
happy birthday
As a 20-year-old, seeing that video title pop up felt a little targeted, but it's kind of a beautiful thing to be reminded that we live in such a new world. The Appalachian mountains have existed longer than bones, but for humans, 20 is not the most precendented age! Crazy
This is insane! I was just thinking about this question and then I open CZcams and this video is there waiting for me.
This is sobering entertainment. It is good when “labeled” journalism. Thanks for sharing! As a fellow vlogger, I aspire to this quality 😅
this is such a hank video to make, wasnt expecting it from john
Great timing! I’m 20 today!
Happy Birthday! -John
My prayers are going to your brother right now
Glad you explained life expectancy. Too many people don't understand it
I'm glad Pizzmas was such a success! Over the years, y'all have been so honest about the supply chain you've setup to create all the wonderful products. It's nice to know that all the people are fairly compensated and the products are quality.
I just turned 20 a few weeks ago! Being a type 1 diabetic, I definitely would've been one of the humans to not reach 20 if I had been born a bit earlier.
i just turned 20 three days ago. i'm not going to lie, i've been having a crisis about it. about losing my novelty or my youth or just a general anxiety for the passing of time. but it's a privilege to be able to be 20. i forgot that. thank you
Very weird getting this recommended after Hank's cancer announcement. At first I thought John was making a response to Hank's video.
I, too, have never been twenty but I would like to say that I am so glad that I get to be alive at the same time as you and see the impact that this community is making.
Since I turned forty I have been telling myself that I have outlived most of the people who have ever existed. As achievements go, it's a start and a way to tell myself I am fortunate indeed.
