I like. I think it is to big to be a regular stop. Only 1% of the world population survives.
How long is a generation?
If by theory a couple has two kids, and both survive to have two kids, etc, and this occurs at 25 year intervals.
150 / 25 = 6. Six generations have come. 2, 4, 8, 16, 32, 64.
Sixty four persons per first generation surviving couple.
What is the infant mortality rate? Probably determined by tech level, so A like the KFS would have 02% among the Rich, maybe 10% among the 2000. What of the commoners 50%?
Tech Level F 80% or 90% with no medicines, poor diet, and overworked parents.
You could adjust the 64 by percentage. Now this only supposes two offspring. Couples could have more.
The future in TMP is pretty harsh with mutants, monsters, radiation, and biowar plagues still popping up.
I think everything you wrote is well done and plausible, there just would not yet be enough people around yet to fill it up.
I think also that any enterprise this put together and highly function would mean recovery is well along anyway.
What is the Mortality rate for disease, or injury.
