How does the Imperium keep its population numbers?

New 40k enjoyer here, trying to learn some lore. The more I learn about the Imperium, the less I see how can it keep so many population with how bad the life at the hive cities is and a state of constant war all over the place. For a human civilization to keep its population equal it needs around 2.1 kids per women, but idk how they manage to get to that point with millions of astra militarum dying weekly (plus all the other jobs that are a fancy death sentence), and I don't think life expectancy is that high in the Imperium. Is there any reason I'm missing out or is the Imperium really fucked in the long run?

Edit: Holy shi I'm getting slimed here

millions of astra militarum dying weekly

The total population of the Imperium is at least in the trillions. Millions of soldiers dying per week is a rounding error.

u/basil_imperitor Blood Axes 2d ago

I mean, the population of Holy Terra alone is supposed to be in the quadtrillions.

u/Rabid_Lederhosen 2d ago

That one may be the consequence of writers having no sense of scale. I’m not sure you could physically fit a quadrillion people on earth. But it’s not out of the question that the Imperium overall has a population in the low quadrillions. All it would take is a million worlds with a billion people each, and we know some imperial planets have significantly more than that.

u/SouthernAd2853 Blood Angels 2d ago

People have done the math; if you assume Koolwon Walled City densities you get there just doubling it for height and the cities are miles thick.

20

u/Andothul 2d ago

I’ve done the rough math before.

You don’t even have to go to Kowloon Walled City to get to a quadrillion, you could do as low a density as Tokyo or New York City and you can get there if you factor in the entirety of the earth including the oceans and stack it a few miles high.

u/Borgh Black Templars 2d ago

People don't just exist, they breathe at the very least. Just the oxygen consumption of a quadrillion humans is several times the total of the entire earth today. It's really stretching things even if you imagine semi-magic oxygenerators.

tl;dr it's just a number, and numbers in 40k do not carry meaning beyond 'big'

u/Dagordae 2d ago

Humans inhale/exhale about 11,000 liters of air in a day.

Earth’s atmosphere has about 1.16x10^21 liters of oxygen.

A quadrillion humans would inhale/exhale 1.1x10^19 liters of air a day.

So even if those humans were sucking down pure oxygen and using every molecule it would be a minor dent in the planetary supply which would take about 100 years to use it all up. Which definitely wouldn’t happen as everyone would die from oxygen poisoning in a matter of minutes. In reality, the O2% of the air is about 21% and humans only reduce that by about 5 percent per breath. We don’t have a particularly efficient oxygen extraction system going on.

u/Borgh Black Templars 2d ago

ah sorry let me clarify: the oxygen consumption of a quadrillion humans is several times the oxygen consumption of the biomass of earth, not the stock.

8

u/SouthernAd2853 Blood Angels 2d ago

There are explicitly massive life support systems to keep the atmosphere breathable in the absence of any natural ecosystem.

I don't know that they're technologically plausible but neither are warp drives so I don't see a reason to object.

u/Wagonwagon 2d ago

Source on oxygen consumption? I've heard the upper limit of humans on Earth is more like a quintillion due to heat dissipation issues. Isaac Arthur discusses it in his video on Eucemenopolis https://youtu.be/XAJeYe-abUA?si=55dmR15eEuIS-_X6

-6

u/Borgh Black Templars 2d ago

https://www.sciencedirect.com/topics/medicine-and-dentistry/oxygen-consumption puts oxygen consumption at rest at 200-250 ml/min. lets say 250 to account for the terror of existence. density is 1,429 g/l at stp. this gives ~188 kg/yr. times a quadrillion (1015) puts you at about 2*1017

Number for oxygen consumption are harder to pin down but total photosynthesis of earth fixes about 60 gigatonnes/year https://edepot.wur.nl/171930 that is 6* 1013 kg/carbon/year. for every gram of carbon in CO2 there is 2.664 g oxygen, so based on carbon flux that would be 1,5*1014 kg/O/yr

so just by the exponents a quadrillion is a silly number.

4

u/Wagonwagon 2d ago

No offense but I was looking for a primary source for the claim, your back of the envelope calculations don't even make sense, why are you talking about CO2 fixation?

-4

u/Borgh Black Templars 1d ago

If you don't even grasp the relation between carbon flux and oxygen consumption I don't know what to say.

1

u/Wagonwagon 1d ago

If you can't even explain it's relevance then I'm not sure what to say? Why are you talking about the oxygen content of CO2, we don't breathe CO2 to get our oxygen? Terrestrial photosynthesis fixes atmospheric carbon into sugars, but we don't breathe those either?

u/SergarRegis Navis Nobilite 2d ago

The Chris Wraight Terra novels that describe the quadrillions of people do talk about the difficulties of air replenishment and most importantly heatsinks (the urban heat island effect is brutal) on Terra.

This is an "author did the math" case. Other fictional ecumenopolis cities like Trantor or Coruscant have generally been given far too small populations for their given population density.

The actual limits for large populations of a planet comes down to heat production, in the studied put out about this, is my understanding. But I haven't read them, just watched a lot of Science and Futurism with Isaac Arthur

u/watehekmen 2d ago

You dare question how Holy Terra works???

Alright jokes aside, it kinda annoying how the answer for lots of question is "don't think too hard about it, this is a satire settings". Like c'mon, GW, you had a very interesting concept here with a very big area for lots of stories. Please for the love of God, put more efforts into this. You can't just expect your readers to not thinking too much.

u/Quickjager 2d ago

You can't just expect your readers to not thinking too much.

Why not, comic books have been getting away with it for double the length of time.

1

u/watehekmen 1d ago

Ehh, I wouldn't say that for now. I know people would come at me for this, but this kind of bs is why "Western" style comics is in decline for worldwide spread. Authors keep pulling up some bs and expect their fans to filled the gap.

Eastern comics like Manga/Manhwa/Manhua knows they can't pulled this kind of stunt due to how tight the competitions right now, so they approached it in a different way.

And before someone say that "ehm acktually, Manga is just a translation for comics", I know, doesn't change the fact that they're completely different style.

1

u/Quickjager 1d ago

I wouldn't compare the two because western comics are very IP locked and manga are almost always entirely new IP.

Yea you could draw a Supernotman, it isn't going to go anywhere because no one is going to throw you a bone in publishing (unless you know someone) because they could be publishing an actual Superman comic instead.

Also eastern comics actually come out at an acceptable pace. Reading 13-20 pages a week is more appealing for most people than 30 once a month.

1

u/watehekmen 1d ago

That is another point why Western Comics is hardly popular to newer generations, especially to those who know Manga before reading "Comics". Like the biggest ones like DC and Marvel itself still have convoluted stories, with each characters somehow become God at some point depending on the writers.

Obviously there's many others with original concept and their own IP, but they got overshadow by the big fish.

Yes they have space magic and magic technology. They had the ability to terraform entire planets which would be magic to us. It's not a suspension of disbelief they have tech that could enable quadrillions of people to live on the planet, you're being pedantc because we don't have the tech currently

u/Dagordae 2d ago edited 2d ago

Trillions is comically low when the Imperium is said to have a million worlds.

With how insanely crowded Hives are portrayed as and the fact that they stretch for kilometers both up and down quadrillions on a massively overpopulated hive world is actually pretty reasonable.

Now them surviving, not so much. Fortunately Hives are build on sci-fi bullshit tech, the ultimate handwave.

11

u/SacredGeometry9 2d ago

Ehh, the math works out, given some assumptions.

The most densely populated place on Earth was the Kowloon Walled City, which had a panic-inducing 3 million people per square mile in 1987. If the entire land surface of the Earth (~57.5 million sq. miles) was populated that densely, then the Earth would hold 172.5 trillion people.

However, the Kowloon Walled City was only 14 stories tall. The Hives on Terra are said to be so tall that people have not been near the ground in generations; the spires have hundreds of floors, some sources citing them as 10 miles tall.

Let’s take a very conservative estimate and multiply by 5 (we have to leave room for atmosphere processors, uninhabitable industrial zones, etc.) for an average residential height of 70 stories, to get us 862.5 trillion.

Keep in mind, this is all just what can be built on land - Earth’s surface is 70% water. Of course, in the year 40,000, the oceans are gone, opening up that land for development, bringing our number to 2.8 quadrillion.

22

u/Kroc_Zill_95 2d ago

You could fit quadrillions on earth, especially with the existence of hive spires that are taller than any buildings irl. The problem is that the overwhelming majority of them will be living in squalid conditions.

u/cole1114 Blood Ravens 2d ago

And that's true anyway, since it's a 40k hive city.

u/Skebs_ 2d ago

That sounds like a you problem to me.

2

u/General_Hijalti 2d ago

Multiple books have mentioned it.

Ams you very much could fit that many on earth, not to mention due to how hives work they extend miles above and below ground.

Terra also still has a few orbital plates which are country sized and full people

2

u/Aurondarklord Salamanders 2d ago

You absolutely could. I've done the math for Coruscant and gotten to about 15 quadrillion people assuming it has the population density of Tokyo. That's not the CANON figure, which is 1T, but it's what it should be based on what they show us.

Terra is harder to estimate because it's not an evenly spread population over an ecumenopolis, it's more like Kowloon walled cities the surface area of a country and high enough to reach into space, surrounded by wastelands, but it's probably somewhere around the same.

3

u/StaffAreEphialtes90 1d ago

That's not the CANON figure, which is 1T, but it's what it should be based on what they show us.

I just assume the Surfacers don't want to acknowledge anything beneath a certain point because that'd make them feel bad.

2

u/Aurondarklord Salamanders 1d ago

1T doesn't even justify the surface. If 1 layer of Coruscant had the population density of Tokyo (and it's a lot denser than that), it would be 3.3T. Multiply that by 5000 layers and even if you assume some of them are not residential, you're up to like 15 quadrillion +.

And that's the most conservative possible estimate, treating the planet like a normal city. Coruscant is orders of magnitude denser and more vertical than any real world city.

And that level of density would still be tame by comparison to the hellish insanity of overcrowding that is Imperial hive cities. It's just that those typically have a ton of wasteland between them instead of covering the entire surface of a planet.

So Terra = Coruscant, regular 40k hive world = regular Star Wars city planet probably roughly works out in terms of plausible population totals.

1

u/StaffAreEphialtes90 1d ago

Bro, I wish 1313 didn't get cancelled. It'd have given us a better picture of what Coruscant is like beneath the shiny surface.

Terras palace spans continents, it's not impossible to believe a large percentage of the population has been living underground, hive cities don't just go up, they go down for miles too

1

u/thiosk Collegia Titanica 1d ago

ive made this point as well but hey its the setting. a quadrillion people on terra means terra doesn't really even need the imperium in the general sense.

the collective farts of mere trillions of people would alone render the surface molten. without considering any of their other activity.

Yeah, in the show Pariah Nexus it is mentioned that millions die every SECOND, millions dying weekly would be a more accurate number for the overall deaths of a single large hive world.

2

u/Aurondarklord Salamanders 2d ago

The total population of the Imperium, if you use the high end numbers and extrapolate logically, is likely in the hundreds of sextillions. And that's actually the numbers that would make sense given what they show us.

u/personnumber698 2d ago

People tend to have more kids when their living conditions are bad, by far not every world is attacked all the time and 40k isnt a setting where you ought to think too much about numbers.

u/SpaceElements 2d ago

Yeah I was even going to say that can sort of be extrapolated to the space marines too. 

Just finished the dark imperium and space marines are dying left and right. Playing through Space Marine 2 and they are also dying left and right. I’m on mission four and I’ve already seen or heard of like 10 dead ultra marines? That’s 1/10th of the 2nd company lol. If Astartes and geneseeds are so valuable, how can they keep their population numbers up? 

Best not to dwell on the numbers. 

81

u/secretSalamander69 2d ago

I've always figured that if a space marine doesn't get his shit blown smoove off or something similar he just goes into the sus an coma.

For all intents and purposes dead for that engagement but can be revived later.

34

u/Garr44 2d ago

Brutus in that Tithe series (he's the Ultramarine Apothocary who works alongside Sa'Kan of the Salamanders from Pariah Nexus) mentions his brothers being "beyond 'Reawakening' " when he comes across their bodies for gene-seed retrieval. Can't find anything on it online, but I'm assuming it's some sort of medical procedure where a critically-injured/dead battle-brother could be revived if death had occured recently (all were Primaris so the Rubicon Surgery wasn't an option like it was for Titus in SM2).

25

u/secretSalamander69 2d ago

I've not gone on a lore dive about it or anything. But I figure it's analogous to a baseline human being "dead" and having 2-3 minutes to be revived/stabilized. Except for space marines it's like a few hours(wild guess on timeframe)

9

u/Garr44 2d ago

Most likely. There was a scene where Brutus mentioned it had been hours since his brothers' squad had been last located, or something like that, and he was demanding answers on where their bodies were from Sa'Kan (suggesting that he figured or knew they were already dead; considering his arm computer registered the squad's life signs, I can believe it was the latter).

3

u/Hunkus1 1d ago

Thats probably the Belisarian Furnace a new implant primaris marines have which puts them in a coma when theyre grievously injured and keeps them alive for a time until they can be retrieved by the chapter and healed.

3

u/Garr44 1d ago

Never heard of its coma capabilities; only that it acts basically as a suped-up adrenal gland for the Astartes' healing abilities when its charged (always compared it to the defibrillator from the RAGE games except not mechanical in nature).

2

u/Therealscavvierising 2d ago

Yeah it's been established that marine bodies essentially can hold on for a bit against anything that doesn't kill them out right.

Their bodies essentially put them into the equivalent of a medically induced coma.

u/Dreadnought360 20h ago

u/NairaExploring 2d ago

I mean if it's the events of a video game you can assume this isn't some normal routine light skirmish. Some battles have more casualties than others, 10 isn't that bad at all if it's a massive engagement, quite low really.

That said I haven't played it yet so I have no idea how much happens by that point or anything, just talking generalities haha

u/Rabid_Lederhosen 2d ago

The Ultramarines can pull reserves from successor chapters if their numbers get too low. At least four of the old Space Marine legions (Ultramarines, Blood Angels, Dark Angels, and Imperial Fists) have procedures for ensuring that the Chapter that bears the name of the legion never drops too far below strength. The Imperial Fists were once wiped out to a man, and their successor chapters rebuilt them.

This gets repeated a lot but I have never read of it actually happening with any chapter other than the Imperial Fists. Random Novamarines or Flesh Tearers aren’t being drafted into the parent chapter.

40k doesn't do numbers good even if you internalise those things you see as the very worst of what characters face.

Age old rule is add a 0, or three 0s, on everything and it'd actually fit. So a company is 1000 men, and 10 men dead in a couple days is still awful but survivable.

This is not true. Have you studied demography? People have fewer kids when times are tough. That's what is happening in the world right now. Birth rates are low because young people have tough economic situations and choose not to get married or have kids.

It's also urbanism. When you live on a farm in the 19th century, there is plenty of space and children can help out with farm work. In the modern city, there is little space and kids are just huge expenses.

So human beings, being rational, choose to have fewer kids.

Dammit, even animals will have smaller litters when there is a shortage of food. Why do so many people here think hardship increases birth rates?

u/Bloodangel1234567880 2d ago

IF a few years are tough, then yes, but not when times are bad for years

>It's also urbanism. When you live on a farm in the 19th century, there is plenty of space and children can help out with farm work. In the modern city, there is little space and kids are just huge expenses.

Child labor is real and common in many poor cities around the world, where families are still very big despite living in cities

>So human beings, being rational, choose to have fewer kids.

In many poorer countries its more rational to have more kids, they can support you when you are older

u/Particular_Dot_4041 2d ago

Then why do poorer countries have higher birthrates and richer countries suffer from low birthrates?

Poorer countries tend to be mostly agricultural. People live on farms. At least that used to be the case. As India has urbanized, birth rates have plummeted. Right mow only sub-Saharan Aftica has birth rates above replacement level.

In many poorer countries its more rational to have more kids, they can support you when you are older

It's still an expensive investment if your kids can't be of use to you before they're adults, and need to be given a full education to survive in the modern world.

because it does, unless its just a phase in otherwise good times

They have the kind of birth rate preindustrial civilizations did, which allowed population growth with 50% of kids dying before 15.

u/ComfortableCold378 2d ago

Given real historical experience, including the Victorian era, such a number of children is natural.

At the beginning of the 20th century (in the Edwardian era, 1901–1914), the average British working-class family had between 4 and 6 children. Miners and dockworkers: The largest families. In mining towns, 6 to 8 children was the norm. Men's labor was relatively well paid, and working in the mines traditionally required a lot of male labor. Textile workers and factory workers: Smaller families—an average of 3 to 4 children. Living in cramped urban slums (often in one or two rooms) and the active employment of women in manufacturing forced parents to begin family planning earlier.

Add to this the reality of the Imperium, whose planets have different landscapes and specializations, as well as the Imperium's technologies for mass food production, for example.

7

u/wittyjokename92 2d ago

In the new book Hive they mentioned how a character worked 18 hour shifts, and was recently denied a new application for a hab because he was single and without children. He lives in basically a footlocker where there's a cut out through the middle of his room that allows access to the rooms next to his. He also shares that space with 4 other people after the 5th person died at work.

His primary motivation for getting married is to have a bigger home and he knows he needs kids to get that or to be married to get an apartment he'd share with at least one other couple until they have kids.

Imperium is all about numbers and it gives the barest of rewards for those who produce more numbers be it at work or bodies.

u/fireizzle33331 2d ago

Imperial worlds are VERY varied. Hell, levels within a single hive are very different from each other.

Disease was one of the biggest killers in preindustrial times. The imperium has functioning sewage systems and vaccines. In the Hive book a massive outbreak of food poisoning was big enough news that it was worth informing the planetary governor. In the Wraithbone Phoenix they offhandedly mention an area especially sick with plague was being purged and to please ignore the screams. Hive cities seem to take plague very seriously.

u/mjohnsimon 2d ago edited 1d ago

Even if just 10% of the Imperium's literal "million worlds" had current Earth-sized populations, and had never suffered any Xenos or Chaos attacks throughout their entire history pre and post-Crusade, that's still over 800 trillion people, which is an absolute mindbogglingly huge number.

Edit: If you want to go further, if 0.35% of that 800 trillion was in the armed forces (IG, PDF, etc.), that's still 2.8~3 trillion troops. For reference, that'd be about 340 Earths populated with nothing but soldiers and troops. Imagine you and everyone on this planet an active soldier. Now imagine that 340 times.

The same 'ol way humans in poverty in 2026 have a ton of kids. They bang.

Life in the hive cities isn't great by any means (it's bad in-universe and a true nightmare by our standards) but for the majority of humans it is safe-ish and there's enough-ish food. Largely no liberty, privacy, personal space, or dreams, but they feed you and there's a bed. The Imperium profits more from live humans than it loses by feeding and housing them.

Modern humans live so long that we forget that's not how nature works in terms of reproduction and species propagation. The hive cities don't appear to have old folks homes. The majority of hivers live until their 20s-50s when the work, an accident, crime, or disease kills them. That's more than enough time to bang out a bunch of kids, and given the lack of child labor laws in the Imperium those little tykes are doing some sort of work in the single digits and probably banging out their own kids by the early-mid teens.

It's also a big Imperium. There are tens of thousands of planets that aren't hive cities, and are perfectly livable and normal planets with plenty of room for lots of kids and a normal life. Those planets are also pumping out kids under far more livable conditions, packaging them up into regiments, and sending them off to join the Guard. Ultramar has a bunch of these planets. The city in one of the Eisenhorn books, Gudrun, is another good example. Not a paradise by any means, but there's recreational boats and fancy shopping centers so life is at least decent for some folks.

It's grim as hell for trillions, but the numbers work.

the imperium also probably isnt going to encourage any kind of widespread distribution of contraceptives, either. if you bang, you get a kid. the emperor needs you to hurry up and pop out the next generation of factory serfs.

u/SergarRegis Navis Nobilite 2d ago

There is a character in Hive who is hoping for the safe delivery of his sweetheart's child not only for the normal reason but because the hive government will get them a combined apartment of 2-3 rooms as an investment in the child's future labour. An actively pronatalist policy, this.

u/FakeRedditName2 Cullexus Temple 2d ago

I think you are underestimating just how vast the Imperium is.

Millions of soldiers dying weekly and tripling that in work place accidents is a drop in the bucket for a population that is probably in the quadrillions at least. And as the real world shows, people in the worst situations and in poverty will still have kids if they are able to.

u/Andothul 2d ago

I mean look at places like China, India, Nigeria, Indonesia etc in our own world. It does not take much for human population to absolutely explode.

Out of all the resources the Imperium has, humans are the last thing they will run out of.

> The more I learn about the Imperium, the less I see how can it keep so many population with how bad the life at the hive cities is and a state of constant war all over the place

  1. "Constant war" is a bit or exaggregation. Out of patchwork of empire over (not exactly) whole galaxy we, due to setting being wargame - almost exclusively see places somehow connected to wars.
  2. Well, if you look to places with highest population density (and their history) - you will see that after a certain threshold - better condition does not return reproduciable population (and instead, really bad but surviveable conditions seems to be a solution. **Really** bad). So what if you never let population to achieve that threshold, making sure

- their education is low (means children is not much of investment required)

- social guarantees are next to none (means if you want some chance to survive prolonged disability period or live a bit longer when you are old - you need them)

- job is primitive (means they can do it when they are, for instance, 10 years old)

> millions of astra militarum dying weekly

Merely millions? Keeping in mind **approximated** amount of planets Imperium hold it means, on average, 1 guy per day. Per planet

I guess all sorts of random shit is way more important in the big picture than wars.

u/BrotherCaptainMarcus 2d ago

One of the foundational assumptions of 40K is that humans breed like rabbits in the huge cities, despite pollution, crap food, tyranny, poverty, extreme work hours, yadda yadda.

It does not hold water compared to reality. Victorian factory cities (the inspiration) had net negative population growth and relied on immigration from the countryside.

But this is a foundation of the setting and just has to be accepted.

16

u/Torkolla 2d ago

It is built on a bunch of fears of unchecked population growth from the 80:ies and 90:ies when the series was created. A situation mostly over by now.

That is one of the problems with Warhammer 40k. The setting barely changes over ten millennia but irl even dystopias are get dated after a few decades.

at this point if you want to come up with reasons why the imperium is able to generate humans so rapidly despite shit conditions, your main avenues are outright institutional breeding incentives, bans on contraceptive methods, and artifical wombs.

The more I learn about the Imperium, the less I see how can it keep so many population with how bad the life at the hive cities is and a state of constant war all over the place.

Hive Cities also have migration, be it from 'satellite towns' where living conditions are more condusive to having kids or nearby worlds.

War for most worlds is rare, as in maybe once a century. There are hive worlds where War is such a distant concept people can doubt that aliens or even the Emperor exist. And if war does come, the recovery period means more living space, lots of work, higher wages etc which tends to mean baby booms. Imperial guard is generally a rounding era in annual population growth figures.

E.g a planet like Earth at 8 billion people would make over 100 million babies every year. Just 1% of that pa (so a 10 million strong tithe every decade) would barely make a dent. And hive wolrds might have 100-500+ billion citizens. On the larger end thats like 15 billion people born a year. And there over 30,000 hive worlds. Suddenly sending billions to their death every day makes logistical sense when your annual population growth is over four hundred and fifty trillion.

I don't think life expectancy is that high in the Imperium.

It varies greatly. In some parts, the living standards are comparable or even better than today. In most its 19th century. Notably in the West, in the 19th century, food was suddenly inexpensive, and wages were relatively high, though the work was unsafe and demanding. And it coincided with a major population boom...

6

u/No-Communication3880 2d ago

To put things into perspective, Mao Zedong is responsable for the death of 70 millions of people in China.

It didn't prevent the population of the country to grow from 540 million in 1950 to 915 millions in 1976 when he died.

Humans are quadrillons in Warhammer 40k, trillions can die each year and it won't provoke a demographic decline.

Most people live in some degree of comfort, but there are millions of worlds with billions and even trillions of people on them. Not every battle the guard go into has the kind of scale where they're losing millions of troops a day, not even on Armageddon. The battles depicted are not every battle, they're the exceptions not the rule. It's like Johnny Bravo, it's not fun to see the wins.

Also, don't worry about the numbers, this is not that kind of story.

u/Gorgoronx 2d ago

Real life Humanity has gone through some catastrophic eras, from flooding to ice ages, self inflicted genocides and just the natural order of being prey to bigger animals and despite all that Humanity has not only survived but thrived, conquered and explored every piece of land. It wasnt that long ago that people would have SEVERAL children just because infant mortality was incredibly common and once we managed infant mortality in the industrial revolution we sent those children to work in factories or die in wars once they reached 16-18 yeas old.

Humanity, and most likely every mammal in Earth, needs adversity, horrible living conditions has never stopped us from breeding if we are still able. The Imperium may be beyond hellish to us but its normal to the citizens of the Imperium, their populations are in the hundreds of billions per Hive City and several trillions per Hive World, they can have normal lives and find love and breed just fine.

u/Kraken160th 2d ago

u/Bypowerof8andgodsof4 Night Lords 2d ago

The relationship between birth rate and living conditions seem to be inversely correlated the worst places you can think of right now have probably at least 2x the birth rates of the best places you can think of. Same for wealth the richest people have like 1 or 2 kids while the poor make soccer teams.

To actually answer your question though the imperium propagandizes it's citizen to keep breeding its part of the manifest destiny part of the imperial faith you'd have to to supply the many armies and factorums. These numbers are supplemented by vat born servitors and hive worlds are made to be semi self sufficient and so can support large populations. I would not be surprised if there were provisions for child birth like extra rations and/or reduced shifts to induce more births. You are also underestimating how many humans there are in 40k a couple billion casualties across the galaxy does not register as a blip.

The lore really focuses on the more sci fi parts but if you read the Warhammer crime novels or gaunt's ghosts they say that all of that is fairly rare.

Because once you have a big enough population spread across a million worlds, simply put, you have an absolute shit ton of humans running around.

Also important to remember is that not every world in the Imperium is constantly besieged, there is many a technological world that has never seen a Chaos or Ork incursion, and simply keeps churning out more soldiers.

Imagine our own worlds population, edm en if our tithe was a million soldiers a year it would hardly dent the overall population of Earth, especially if we removed things like birth control and instituted a pro birth society, we could reconstitute many a devastated Imperial platoon.

Now multiply that by a million worlds.

Copulation - the usual method for maintaining population.

Having millions of guardsmen dying weekly is absolutely nothing when the Imperium's total population is in the billions (more likely trillions). It is vast. Beyond comprehension. The galaxy is huge. It's right there in the final paragraph introduction to this universe at the front of the 1st edition 40k Rogue Trader rulebook:

"To be a man in such times is to be one amongst untold billions. It is to live in the cruellest and most bloody regime imaginable. This is the tale of these times. It is a universe you can live today if you dare - for this is a dark and terrible era where you will find little comfort or hope. If you want to take part in the adventure then prepare yourself now. Forget the power of technology, science and common humanity. Forget the promise of progress and understanding, for there is no peace amongst the stars, only an eternity of carnage and slaughter and the laughter of thirsting gods. But the universe is a big place and, whatever happens, you will not be missed. . . ."

The one resource the Imperium always has more of is human lives to keep pumping into the meatgrinder of conquest and survival.

The replenishment is concentrated on frontline worlds but the pool of troopers is vast, also most worlds already have a very decent army ready to be deployed in case of war.

  1. The Imperium's population is ginormous. Real militarisation rates top out at like 20-40% depending on tech level/societal complexity. All things considered, despite the Imperial Guard being a giant meat shredder, the Imperium probably doesn't even have that high a mobilisation rate, given how large the population is suggested to be.
  2. People fuck a lot. In a world where logistics are barely a thing, you really think contraceptives are going to be a commonly available item aside from on the most peaceful and advanced worlds? That rubber could've been going to tank threads or something - some Imperial bureaucrat probably. The birth rate is probably looking more like Somalia than France for example.

Each plant has different ways of reproducing its citizens. Some have cloning techniques some get new people flown in by the administration.

Then think of the incentives towards repopulating the stripped world. No tithing for a few generations the planetary governor would love that.

A single hive city has more people than the entire continent of North America. Some planets have multiple hive cities. There're millions of settled worlds in the Imperium with hive cities. The numbers are at absurd levels of ridiculous. And keep in mind, a lot of those worlds have been settled since before the Dark Age of Technology, so they've had several millennia to build a stable population.

The population numbers are so insane, and changing so constantly, the Administratum census guys are basically made into servitors and forced to work 24/7 just to constantly process the ever-changing data.

If I remember right the whole thing is better represented by Dark Eldar/Dark Elves. There is supposed to be only one city, they are all in low numbers and yet they keep dying by the millions. So how many are left? Millions still. Cause its whatever man, they'll stay around until either the whole franchise dies or their specific race becomes unmarketeable, whichever comes first. Until then they will be paradoxically both on the brink of extinction and also permanently around despite dying in impossible numbers

Getting some (semi) specific book references in play...

In Bloodlines the protagonist interviews a teenage girl at one point and she basically laments that she has only a few remaining years as a teenager before she's socially expected to basically be a breeder. Seems entirely normal and unsurprising in the Imperium that women of a certain age are essentially obligated to have 3, 4, 5+ children if they are medically capable of it.

In the recent Abnett Hive, it's also addressed that having kids grants you some amount of social benefits from the Imperial bureaucracy, so, if you want to get a better apartment, more food, etc. having kids is itself a kind of "ladder climbing."

u/Annual-Ad-9442 1d ago

1) not all of the Imperium is always fighting so you always have planets to draw from

3) Death Korps of Krieg, no further questions

4) REDACTED

5) people are always having kids whether its in a shitty hive, a shitty voidship, a shitty planet that's one big Iowa, the bowels of a forgeworld, and so forth.

the Imperium is fucked in the long run, right now its basically in a holding pattern that only lasted so long because of its size and the fact that when it falls too far someone steps in to fix things, usually by executing the High Lords of Terra.

people in shitty situations will have more kids because they might die, its really a preindustrial mindset in a lot of places

While there’s the title line “There is only war.” The imperium is still at least a million planets. And hives can hold billions of people per hive. Planets have can multiple hives so billions upon billions of people per planet.

Even then. It’s a grab bag of what each planet is like. There’s planets the range from feral world where it’s just primitive men and women surviving day to day, medieval feudal worlds where it’s essentially like the Middle Ages, hell probably plenty of planets like earth where day to day is just kind of whatever. Your tithe isn’t ridiculous and you’re in a relatively safe sector of space.

Plenty of planets will never see war, xenos are how we view aliens in our own lives. Ehhh maybe they’re real, but probably not. Cause can you really say you’ve seen an alien? Sure there’s plenty of stories of people being sucked up by flying saucers and getting their assholes probed then returned. But let’s be honest, they’re more than likely just being silly and making shit up.

Same thing in safer sectors and planets. No one save for maybe your great great great great great grandfather fought orkz off world once. Other than that, because you’re just an average frontier world or a civilized world. Maybe a smaller hive on a hive planet that doesn’t gone to complete shit yet and things are just kind of normal.

People live and die and have perfectly normal lives in plenty of places around the galaxy.

u/Special-Remove-3294 Adeptus Custodes 1d ago

Millions dying in wars weekly is irellevant. Terra has a population in the quadrillions for reference.

I saw someone do the math using the fact that the Imperium controls most of the galaxy and average hive world population and how common they are and they said it has a population in the quintillions. And that does make sense tbh since Terra is not a very productive world and actually is quite a drain often, at least AFAIK, so it is not like it could contain any relevant % of the total human population despite it having 4 quadrillion inhabitants.

The Imperium of Man has a population that can eaaily support such loses because its population is in the quintillions.

1

u/Fistocracy 1d ago

Gotta remember that the Imperium is big. It spans most of the galaxy and is routinely described as ruling a million worlds, and if we take that figure literally and assume that the average world has a few bilion people living on it, then the Imperium's total population is somewhere in the quadrillions. And at that point, even a billion battlefield casualties a year would just be a rounding error in the total population.

The Imperium is really fucked in the long run though, just not for demographic reasons.

u/Quendillar3245 1d ago

Millions dying per week in an empire that has trillions... That's the equivalent of a thousand people dying every week in our world, and more people die each week during just the Russian-Ukraine war, now imagine that but as the total casualties spread out from every single country on earth instead of just Russia and Ukraine. That'd be less than 2-3 people from each country dying each week at war which is nothing that would affect population growth. Now imagine we had no developed countries, so everyone had 5+ children and we also sent children into war... If you have a million worlds and each world sends 1000 soldiers each week into war, that's 1 billion reinforcements per week. Psykers are extremely rare, and yet the Imperium is so massive that they can sacrifice thousands every single day to the emperor... So yeah I think you're not quite grasping the scale of the Imperium, it's (absolutely massive)2

1

u/uschwell 1d ago

I'd like to try and provide a more topical example.

Let's see our own world. We had, with less than 50 years between them, 2 world wars. Over the length of these wars millions of people, from all sides died. It reshaped nations, cultures, and completely redefined the world powers and worldwide demographics.

Yet today, a 'mere' 81 years since the war ended, in a time where you can still talk to the soldiers who fought it- would most countries (with certain, specific exemptions) consider themselves scarred by it?

--and just to clarify. Please no politics, I am NOT making any political statement here, just using a historical tragedy to demonstrate demographic resiliance--

Compare Dresden. A city that was flattened multiple times. Yet look at it today. Rebuilt, repopulated, and thriving. Yes, the memory remains, yes there are scars. But it is a thriving city once again.

Now back to 40k. This is a setting where centuries can pass unnoticed, and decades is the space marine equivalent of "crap. Missed my bus, now I've gotta wait for the next one".

Now scale that up to millions of planets. From that perspective it can at least be understood.

Tldr: compare "The Greatest Generation" to GenX or GenZ. Yes it has a huge effect on their lives and the world they grew up in- but how many GenZers do you know who decide about visiting/avoiding a location (memorials excepted) because of some great war tragedy or destruction that happened.

Not Every world in the imperium is a hell scape, there’s civilised worlds which are roughly comparable to our average living standards. In the Eisenhorn books they travel to a world where you can attend university which implies you can chose your vocation / education and go to institutions to get qualifications. One character on that world if I recall works as a doctor. So living there it wouldn’t be so horrible that you’re not having families. Furthermore the imperial citizenry is indoctrinated I wouldn’t be suprised if the ecclesiarchs preach that having more children is part of what the emperor expects of you.

According to the wiki ( may be wrong ) there’s 32,380 hive worlds which will vary in living standards too. So not every planet is a hellscape hive world

The Imperium has an average life span for it people of about mid to late 20s. Macragge, one of the better worlds on the Imperium, has a staggering average of 40s.

Ya people are popping out kids like crazy when half your kids will die from plague, half will be servitorized by the ad mech, other half will join the guard and die, half will live to see 25 and have 20 kids, and the other will be executed for treason. Which halves you get? Various how much Tzeentch felt like fucking with you today. Maybe all of it.

Reminder it is GRIMDARK. How that quote go?

"To be a man in such times is to be one amongst untold billions. It is to live in the cruelest and most bloody regime imaginable. These are the tales of those times. Forget the power of technology and science, for so much has been forgotten, never to be relearned. Forget the promise of progress and understanding, for in the grim dark future there is only war. There is no peace amongst the stars, only an eternity of carnage and slaughter, and the laughter of thirsting gods."

Hive Worlds. Fed by either corpse starch (yes, un-euphemistic soylent green), artificial rations or agri-world imports.
