This article seems to be Part 1: The Biggest Generation of a series of 5 – links to the other 4 are on the page of the article.
Excellent article on the huge population growth expected as a result of the largest generation of child-bearing age coming to fertility.
One of the comments at the end is particularly interesting for the understanding it hints at about when populations implode:
Apparently unknown to most policymakers and apparently to many in academia is that classical and catastrophic REAL-WORLD population climb-and-collapse outcomes (skyrocketing J-curve growth in numbers followed by 99%-plus die-offs) can routinely and classically occur in surrounding environments that remain 99.998% UNOCCUPIED and which appear to remain seemingly-available for further occupancy – in other words IF the leaders and scholars of a sentient population with a skyrocketing population WAIT until the combined bodies (or cells) of the population involved physically-occupy roughly 2/1000ths of 1% of seemingly-available “vast open-space” conditions they will have waited “too long.”
In other words in ALL THREE classical cases we reference above the subject populations exceeded the carrying capacity of their respective environments at peak populations that physically occupied about 2/1000ths of 1% of their surrounding environments so that at the moment they reached the 2/1000ths of 1% occupancies they had already waited too long and it was already too late because their collapse and mass mortalities had already begun.
