I think you have to distinguish between the number needed for group
survival and the much larger number needed to maintain a civilisation
and the required admin systems.
I've been watching several documentaries recently about the
disappearance of ancient civilisations and I get the impression that
their demise had little to do with the size of population.
Drought, flood, soil damage (erosion, over-use, etc.), famine, crop
failure, plagues, all over a long period, ended civilisations. A few
encountered large disasters (e.g. Crete). They could cope with short
events fine, by economising and some population reductions. Many had
extensive irrigation, storage and trade routes. But events like
100-year droughts were too much. The population shrank, the
civilisation collapsed and the survivors wandered off or survived in
small groups. Eventually conditions improved and large invading
nations from outside took over the land.
