It's likely we've severely underestimated the human population due to discounting rural areas.

China's population is lower than projected. Many of the models that predicted a higher population counted an extra 100 million for China when they are actually short 50-200 million.

It's likely we've severely underestimated the human population due to discounting rural areas. While I'm not going to give any specific figure without more evidence, it's likely above 8.2 billion (which is already not a small number!)

I don't think the world is going to be a very nice place to be born into in the near or long term future. For that and other reasons, I got sterilized a few years ago. I also donate to charities to educate girls, as educated girls will have fewer, healthier children. There's a lot of horrible things going on that I, unfortunately, have no control over. This is one of the few I can control in some small way, so I've acted in what I believe to be the most ethical way available.

It's also worth noting that the Global North (distinct from the Northern Hemisphere) consumes far more resources than the Global South does. Waste generation correlates heavily with wealth, and yet with climate change, the poorest countries will bear the worst of it despite having the least responsibility for creating it. I also expect this to be exacerbated by recent elections.

Sterilizing yourself to make the world a better place for... who exactly? The whole point of caring about the future is the implication of future human generations. There are trillions of planets untouched by humans out in the galaxy. The only thing making Earth special for us or worth protecting at all is the fact that humans live here.

I can't say much about the Economical/Logistical perspectives, since it simply isn't "my Metier".
However I can say that sociologically, this demographic shift causes some heavy issues.

In my country, there are almost thrice as many 50-90-year-olds than there are 20-50-year-olds.
I took that cutoff point because the likelihood of a citizen above the age of ca. 40 being capable of understanding and comfortably navigating the internet and modern digital media drops drastically, but not to zero.
Anyway, this causes several major issues:

With the skyrocketing cost-of-life and housing prices, the "fit to work" are already overburdened but have to prepare their asses even harder because, within the next decade and onward, their tax money has to support several times the amount of pensioners per capita.

Pensions have also not been properly inflation-corrected, so an overwhelming amount of elderly live in abject poverty despite having wasted their lives to wage-slavery. That, understandably, causes them to be rather disgruntled.
Unfortunately, that absolutely justified anger gets vented on unjustified targets, such as immigrants, the disabled, the sickly and communists (It's always the commies ffs) because it's a lot harder to question the fundamentally unjust and exploitative system we live in, and even harder than that to reflect on your own life choices and concede that you yourself had a hand in your lot, having wasted your unfulfilling life being a wage-slave for said exploitative system. (It's more complex than that, but you get my point.)
In contrast to that, hating on the Foreign and Different™ is just so, so much easier and satisfying, as Warhammer 40k has taught us. (IMG:[invalid] style_emoticons/default/tongue.gif)

Let's get back to that cutoff point I made, grouping people into being "digitally native" vs. not knowing how computer work:

The lack of Information Hygiene and Media Competency in this clear majority of the population presents a very potent Petri dish for the spread of disinformation, emotional/alternative facts and socially destructive radicalizing stances.

To speak plainly:
The elderly are endangering civil liberty and the foundations of our democracy because their burgeoning senility, coupled with a stubborn entitlement and a refusal to learn new ways is met by predominantly extreme-right-wing/Fascistoid/anti-democratic Actors, who use a type of Grandchild scam to instrumentalize stupid crusty boomers into giving their Votes to said Actors' troublingly inhumane agendas because said crusty boomers can't tell apart an AI image with reality for shit.
It wouldn't matter if everyone across the ideological/philosophical spectrum would "play dirty" that way. That would return things to a halfway normal distribution, but as it stands, Nazis are excellent at making old men yell at clouds.

This issue has gotten rampant enough that some circles seriously start thinking about revoking a citizen's right to vote at the age of about 80.
That is its whole own can of worms and from my POV could only solve surface-level issues temporarily, with the whole point becoming moot in a generation or so, when digital natives have become the new elderly. And the state wouldn't be capable to implement this change within the next 5-10 years since it would be a deep cut into our "unalienable" part of the constitution. So IMO that debate seems rather pointless.

Anyway, I wonder how that translates to other nations with a similar demographic trend.

I can say it feels relatable where I am.
