If you wish to avoid spoilers, do not watch the trailer. I remember talking to my kids about the movie and then watching the trailer, and it gives away pretty much 100% of the movie.
The Expanse series (James SA Corey) makes a rather different prediction about the effects of plentiful (or at least mostly sufficient) food coupled with a decreased need for human labor.
In that story, in the future there are far more people than jobs (only on Earth--not so for off-world settlements). As a result, most Earthers are effectively on welfare, including many people who want to have a job. With little or nothing else to do, they start having more children, which results in the population of Earth increasing to ~30 billion.
Busy everywhere but also downtown is full of empty buildings and you still need to commute from Glendale even if you're an LA detective running down replicants.
Ads are talking up off world colonies in Texas.
No traffic though, so that's where it's fiction.
Really though the entire fiction relies on the contrast of inventing slaves in giant, monstrous firms while still having plenty of forgotten underclass, huddling in the lower ruins. Deckard is middle class, commuting from his empty suburb to prop up the system.

TLDW: People in the past had more kids more often because of high mortality rate and having a care-taker (mother) at home.
With child mortality being lower, plus women entering the workforce and enjoying a higher standard of living, most people won't want to have more than ~2 children. They want to spend their money on having a higher quality life rather than subsistance and survival.
I recently read Niven's ringworld (1970). All the intelligent species had overpopulation problems, dealing with it in different ways. It was just a given that it was an inevitable consequence of an advanced species.
It was really jarring to consider it. I'm old enough to remember the (now recognised as disastrous) one child policy of China but even so the way it was presented as "of course there have to be population controls" actually took me out of the narrative.
The West was in no way contributing to "overpopulation". It was other areas of the globe that were causing problems.
