I wonder how accurate the population projections of 2100 will end up being. 50 years back(roughly speaking) people thought that the population would keep increasing for a long time yet now we see that it's peaked or going to peak soon for many countries. Maybe just as how those predictions were wrong, so could our projections?

Russia's population pyramid is one of these you should look at. It has a lot of "waves" of people percentage in middle ages. It is echo of ww2, where a lot of young people, potential fathers were killed at the front in 1941, and not only after ~20 years, but even after ~40 years after war, number of born children was much less, than is other years

On a smaller scale I live in the capital of the province of BC in Canada, it’s called Victoria. We have the highest proportion of people over the age of 80 in the country. I can see the demand for health care and living assistance for this population. As we move more in this direction you have to wonder if everyone’s needs will really be met.

South America: Am I a joke? Oceania: Yeah. It's rough buddy.

Would be interesting to see Nigeria's population pyramid through the ages up until 2100

What these graphs don't account for are wars, economic and political turmoil moving forward and migration. They just account for current trends, which one could hardly argue will continue unhindered. Take any predictions after the year 2050 with a huge grain of salt.

India, the US, and some developed nations in Europe would have been nice to see and compare with those shown in the video.

The one thing I think that would have improved this video would have been to show a sample of 5 different nations with 'typical' demographics pyramids at the start. Greenland and Antarctica would have been interesting additions, if purely because of their exceptionally low populations. Antarctica surprisingly also has the lowest infant mortality rate of any continent - 0%; with 11 out of 11 babies born there surviving.

Birth rate is the biggest influence over social, political, and economical policies of a country.

The male to female disproportion is always so heartbreaking. Female infanticide is despicable.

There is a far, far worse problem to consider which is the accelerating pace of industrialization. The first wave of industrializing countries took over a century for the balance in their populations to shift from rural to urban. The latest wave is going from heavily agrarian to mostly urban in a generation and to being able to sustain population increases unlikely any in human history. They are able to do this thanks to the integrated global economic system. if that collapses due to war or due to a big country like China or Russia saying that they don't like the current rules and really being willing to enforce a change in the waters they can reach the entire system could collapse. If that happens, Africa will experience the mother of all famines.

You should have included Eastern Europe, India and USA. Other countries like Iran, South America and Bangladesh would have been interesting. ( because they have managed their birthrate in a short period of time).

It'd be cool to see these graphs with the raw numbers instead of just percentages... I feel like it'd give a better idea of what has happened through the years

Do a video on the lancet study on the population projection of the world - their projections are even more stark and drastic with China being halved by 2050

i wonder what it would be like to be 80-84 in Niger

An important thing to note is that our measurement of "development" is also a measurement of how much is spent on a child in all aspects. Which isn't to say that it is cheap or easy to raise one in poorer countries. But an increasing problem in our so-called "developed world" is that the younger generations don't feel like they have the time and money to have offspring in the first place. Japan, with its work ethics that led to a term for working well beyond exhaustion being coined in the 1970s, is a very good example of this. There even are enough people that withdraw from everything for similar reasons called "hikikomori." China has seen movements of a similar vein in "lying flat" and a recent one I've forgotten the name of. If anything, all these are indicative of greater systemic and societal problems that we can't solve with our current way of thinking about work and life.

Your video's are great good job

quality does not always have a full edge over quantity especially since quality is harder to replace and recover. For me, it's finished in battle when all numbers diminished, but it's finished in war when all quality is lost.

Ive lives in Bahrain for most of my life, and I can agree on the fact that there are much more men than women, and most of the men there are adults

Super interesting. Well done, sir!

All this tells us that human population will reach a peak soon. Interesting to see that happening soon. The peak could come as soon at about a world population of 9 billion before the earths population starts to go down.

It seems that in developed countries, population tends to stabilise (neither growing nor decreasing). As shown in those “2100” demographics, people of each age group is in equal proportions. Have Earth reached its capacity to house humans? It also appears that in the future, people will work for their entire lifespan.

This was super cool!

Wow, very interesting, thank you. (I hit the subscribe button.)

I don't know where you got your data from but China has already peaked and it's population will crash the coming decades down to 600-700 million not 1 billion

You missed South Korea's inverted pyramid.

Great video!!

Awesome, my friend. 😍💕 Big like. 👍 Have a nice day.🤗✨

You forgot the Cambodian demographic pyramid. 30% of the Cambodian population died during the 1970s Genocide by Pol pot. Big drop in population for those 40 and older.

What is the source for the projections please?

Cool video

North America would’ve been cool to see

DO NOT PAY YOURSELF FIRST. THAT'S THE WORST BUDGET ADVICE I'VE EVER HEARD. IT UNDERMINES THE CURRENT FINANCIAL REALITY OF THE LOW AND MIDDLE CLASS. BILLS, FIRST, SAVE AFTER.

As a Japanese person, our population pyramid looks like an obsidian tip on a prehistoric arrow

An interesting thing to note is that there is a fertility gap between the desired amount of children and the actual birth rates in developed countries that in my opinion is linked to the cost of living for parents. Children are very expensive in the developed world with it being over 200 thousand USD over the 18 years without accounting for college or a tradeschool and with the replacement rate for the population being around 2.1 on average a parental unit needs to be able to support over 400000 thousand dollars to give their child they want and if they can't with the spread of contraception and safe sex practices they chose not to. Obviously it would be a terrible idea to ban contraception due both the moral and practical effects it would have on the spread of std's so they we can do to safe guard our population from demographic shackle of the older generations taking up an increasing share of our effort as they go into retirement is to increase child care support for parents and make sure they know how they can get support along with fixing the general cost of living crisis that is going through the western world.

I had hoped to see more "world power" pyramids - USA, Russia, Europe, etc

eastern europe would be interesting. sizes can be similar to west but population is way under in some places

Man this video serves as a wake up call to many societies 🤔

All of these metrics assume that no one starves to death when global trade breaks down and half of the population is too old to work.

Some don’t look anything like pyramids but I understand where they got the name.

Most concerning are the projections for the African countries. As things stand today, they are slated for famine and starvation this year. Already they are suffering 50 to 60% youth unemployment. I can't imagine them reaching China's population and having a 90% unemployment rate. How would that even work? Even if they flee north into Europe, Europe is experiencing energy crisis too and would be lucky to make it past the next two years unscathed.

By the time Japan's population ends up with straight sides, the mobile robot population will likely be ten times the population, and the fixed robots in factories 50x.

I am thinking that it is not the population pyramid that matters so much, but some calculation of the absolute number of young people combined with GDP and productivity.

These projections are like taking stock market data and asking Excel to do a forecast.

How are we still holding Elon Musk up as a beacon of intelligence after everything we’ve seen to the contrary? 😂 Great video until that point

I was not able to understand your pyramid charts. It was difficult to read the numbers as they were so small. I would have liked to understand your observations more. Thanks for the interesting videos that you bring us!

The problem with population growth projections is that...its a projection based on uncertain data that is liable to change year on year.

Amazing how it took everybody 10 years to catch up with Peter Zeihan.

Videos like this need to include a discussion about the world's/region's/nation's carrying capacity to give meaning to the numbers.

Do these charts factor improvements in health technology? Because it will make a huge difference in age populations over time

this is very cool

This is a good video but the future projections can quickly change based on changing immigration rates. Also if you look at UN population projections they keep on getting it wrong and always underestimate population growth. It hard to predict the future and if you remove assumptions and simply use the rear vision mirror, so to speak, population growth will continue well beyond the current UN projected max population level.

I'd argue that the country of Niger and others with similar demographics, should be extremely concerned about their future population projections, there is no way a country like Niger could have any hope of sustaining 140 million people, and that's not to mention that the current global food baskets are near max output as it is, along with climate change and underground aquifer depletion that will make food production go on the decline. I fear for the future.

The age old dilemma, mortality or reproduction. The longer the average lifespan of individuals, the less likely they are going to reproduce. Vice versa.

We'll go from an overcrowded planet to deserted one lol

How could West Africa’s population reach 1.4B if the region becomes less and less habitable? If they experience climate collapse, there won’t be the human development required for population growth

Thanks for the video! This is a fascinating topic. It bothers me a little that you talk about the projections as if they were set in stone. They definitely aren't. Things change all the time, and the chances that the populations in 2100 will be as predicted are pretty slim, in my opinion.

These would make more sense if, instead of age, the left side of the graph showed birth years.

Nice video but I hate people quoting that from Elon Musk. He isn't educated in this area and would do well to not spread potentially harmful opinions that are not based on facts. I suppose I could say I have a reasonable knowledge of this subject having a background in biology and sustainable development and having done projects specifically on this issue, so will just throw my thoughts out there. The reality is that as a planet we are insanely overpopulated and the population is still growing, not decreasing when we take into account every country. Every single issue we face as a global society, from climate change, to resource depletion, how we're going to feed ourselves, energy, biodiversity loss and even a lack of jobs and violence, would be far easier to deal with if we had less people. The population MUST come down. We either do this willingly or nature will do it for us with disease and starvation. The demographic problems in regards how to deal with an aging population are obvious but we should be looking at ways to deal with them and make the transistion to a stable, smaller population as painless as possible, not ignoring the future consequences of billions of people on this tiny planet for short term benefits. If we had less people in the world, individuals would have more access to their share of the world's resources, land, food, 'money', there would be more to go around and regular people would have a better quality of life. We see this after catastrophes like the black death in Europe that killed 1/3rd of the population. Life for the survivors was good, people were richer, their labour was more valued because it was a rarer commodity. This of course was not appreciated by the social elite who could no longer force competition for cheap labour and could no longer pay people pennies as the labour of the poor was now a rarer commodity and therefore more valueable. Employers had to compete for workers, not the other way around. People could pick and choose jobs, they could work less hours etc. Having a billionaire like Elon Musk claim he wants more people in the world feels quite ammusing in this context.

I’d like to see the different graphs without changing the scale from past present, future

"This year, Earth Overshoot Day fell on July 28" so to keep using resources as we are now, we need to half the global population. seeing how many live in poor conditions, for everyone to live a nice cozy life, we probably need to get it down to a third or even a quarter. these projected population pyramids are nowhere near what is needed. i see massive wars and famine within my lifetime, climate change alone wont be enough to equalize the imbalance.

6:33 that's actually Sossusvlei, in Namibia, in Southern Africa. Very far from Western Africa.

It would be interesting to look at the Russian age pyramid, given the huge number of young males being lost to war and how that affects them in future years.

The question of how future populations will cope is often answered with innovations. We are a lot more productive now per capita than 40 years ago, and technology has a lot to answer for that. So when you ask how we’re going to cope with an aging population, the biggest challenge is going to be social care. It’s manual, labour instensive work, and it doesn’t pay well. It uses up a lot of human capital that would otherwise be used in more valuable economic activities. The solution is innovation. If you can for example design houses that cater for reduced mobility, then that can mitigate the need for social care. Better designed products (e.g. kitchen, bathroom and laundry products) that address physical impairments will become more prominent. Cognitive impairments are more difficult, but I do think we’ll see innovation here too.

The "thing" is NOT a pyramid, but a DIAGRAM! (Calling it a pyramid suggests that there is a NORMAL form of the population diagram - which there ISN'T!)

Long may the birth rates across the world continue to decrease to enable the world's human population to reduce to a sustainable level - that at the beginning of the 20th centuary at most. Economists tend to live in a make-believe world where growth is a good thing in order to fund, amongst other things, care for the elderly. However, we live on a finite planet that cannot keep on giving just because humanity has overcome nature's natural equilibrium. We currently over-consume all metals. These are not only non-renewable, we, as a planet, do not recycle even a small proportion of all that we use. For example; in (approx) 2009 it was estimated that humanity had extracted approximately 50m tonnes of gold (a metal with probably the highest recycling of any). Of these 50m tonnes, 25m were extracted up to 1948 and the other 25m in the following 60 years. Urban populations are dependent on man-made infrastructure all of which uses very large amounts of metals, the usage per capita continuing to rise. This, combined with a continuing population increase brings forward the day when humanity will have to revert to primative life-styles that will have been largely forgotten. Nature will ultimately win abck the much-changed world.

South Korea : Will be a pyramid shape with INVERTED, LOL!!

I'm dubious about long-term projections. Also, we should point out the advantages of older populations and fewer people.

It seems like the demographic projections going into the future are optimistic.

Do the estimates of China’s population reflects the news that they over counted by 100 million on their most recent census? I’ve heard some estimates that by 2050 they’ll be under 1 billion, also the I’ve read the change to child policy wasn’t as effective as it was hoped to be due to the fact that Chinese couples had chosen housing for a family of three and not a family of four. When people say an a authoritarian Regime is better than a democracy because they can get everybody going in One Direction, they assume they’re going in the right direction. But when they go in the wrong direction it’s an absolute catastrophe.

Declining population is actually good. Less people living in cities with infrastructure for many more is a great thing.

The most warped population pyramid was the USSR. WW2 made the pyramid look like a pear in that period.

The China data doesn't appear accurate. The recently published 2020 census (trickling out because it's so bad) has China's population dropping below 650 million by 2050...and shows China overcounted young women by 100 million in the previous census (regions get funding according to population so there is high incentive to inflate the numbers). China is now the fastest aging country in history and facing demographic collapse thanks to decades of the One-Child policy.

Where did you get these from? China looks suspiciously symmetric, considering the preference for male offspring during the one child policy.

My critique is these projections assume a pretty static society, that countries like Japan and Italy, will try to maintain the order of things, and therefore keep the column like look of their population graph. This does not predict any sort of baby boom or deurbanization that might occur that would also increase birth rates. Of course no one can really predict those sorts of things.

I expect global warning will force a lot of people to move from warmer regions. We should expect 3 degrees warmer climate on average in 2100 and 6 degrees warmer in 2200. Nobody knows how long the temperatures will increase at it’s current speed.

Yeah, more older people than younger people is a problem but we also can't just pop out more and more and more babies with every generation, what about overpopulation? oO

It's absolutely remarkable how 99% of places have a 50/50 split for male/female. The 1% with far more male than female, it saddens me to believe that maybe so many were never even given a chance to live... If that isn't the case, then what is?

Interesting

I wonder if the PR in any country are being counted for their original country or for the nation they are living with????

8:22 Geography Bible raps! "you can clearly see the huge amount of babies being born" *Beat skips* "Children under the age of 4" Imagine if he did his entire vids like this

I was hoping to see the Soviet Union's pyramid. During WWII they lost most of their military age male population which skews their demographics to this day.

China is among the countries with the most skewed sex ratio at birth, according to a recent Pew Research Center study of UN data. In fact, China accounted for 51% of the world’s “missing” females between 1970 and 2020, due to sex-selective abortion or neglect, according to a 2020 UN report. While China continues to have a skewed sex ratio at birth - 112 male births per 100 female births, as of 2021 - this is down slightly from a high of 118 male births per 100 female births between 2002 and 2008. Still, as of 2021, China had a huge overall sex imbalance of around 30 million more men than women

A good point of comparison would be Canada, with it's low birthrate and heavy immigration together allowing public policy to determine population growth rate.

There are too many variables to consider when predicting future populations in the various countries. Climate change being the main one. I do believe unless world population growth is checked, due to drought conditions around the world, agricultural production will be insufficient to feed everyone, and millions and millions will die of starvation. Great parts of the world will become uninhabitable, leading to massive dislocation of populations, and armed conflict will ensue, leading to the death of milllions more. Those countries with nuclear weapons will be using them, I am afraid to say.

U forgor India

Ngl when I was a kid and saw the pyramid with the shorter bottom than the middle I was like hold up. Isn't it gonna topple over with so little support?

I see that your future projections for longevity are universally increasing. And yet this population characteristic is one of the hardest to achieve. Is this just hopefulness, or are you deliberately concluding no wars, famine, or pandemics?

Respectfully, citing Elon Musk harms your credibility. The man says what he does to get a quick buck, not from a genuine source of intelligence or compassion. I think it would be better to instead cite an academic or even a research institute in the future.

So what will the presentage of world pops will be in Africa, Asia,Europe,Americas?

My geography teacher showed me that

Everyone I know that has visited Japan recently loves it. Maybe it's not so bad to have this happing?

While I agree with Musk's view on the decreasing population, citing him is still cringe. There are so many other people who study the field that could be mentioned. Not that emerald rich, union busting, vaporware spewing guy.

I think it would have been interesting to examine why Saudi Arabia and Kuwait have that lack of women in their pyramid.

Bahrain and UAE can be described as "population hammer".. i mean look at the shape

Population reduction is good for the planet. 🌎

First

I also find it fascinating how the world evolved to a point where pronoucing a world country properly is problematic, so it is rather pronounced wrong with J in the middle with French accent not to cause any controversy..

Is the Asia's graph exclusive of China and Japan? Why are they mentioned separately?

Well, in todays world the graph is going to be wild^^ How do you fit 174 genders in one pyramid?^^
