[LMB] Nexus population

My mother was one of seven siblings. Her mother was one of eight. I don't
know how many brothers and sisters her father had--he had one full sister
and both his parents were widowed with children from their first marriages.
My father was one of three, however, his mother was one of five, and his
father had had more than TWENTY older siblings...
This of couse was pre-automobile-as-main-trasportation...

Over 800 years (or however many), 80 billion is 100 million a year.
Over 250,000 (five Barrayars!) a day.
I don't see Nexus space travel having anywhere near that kind of
capacity. Especially before gravity compensation, where ships weren't
accelerating nearly as fast.

To the extent that this is a factor, I think it's more due to the
local environment (NYC, say) unconsciously feeling overpopulated,
rather than the entire planet on an abstract level.
