"On a colony world, where growing the population is a priority, generations would tend to be substantially shorter than in a modern post-industrial society where population growth is more restrained."
But Deneva IS a post industrial society.
You can't make a facile comparison with Earth here, since the situation is obviously different. Here on Earth, which is already heavily populated, there's not much incentive
not to allow the population growth to fall once a society becomes post-industrial, and indeed plenty of incentive to decrease the growth rate to zero. But it should be self-evident that on a colony world, there would be a much stronger incentive to grow the population.
Besides, we're both in agreement that indigenous procreation would make a trivial contribution to the overall population growth, so it would be pointless to continue to debate the details of that portion of the analysis.
You expect people to give birth to children at 15 years of age, as opposed to 30 years, just because they're in a colony, thereby shortening the generations?
I never specified an age. I would've said 20-25 myself. And again, why are you continuing to argue about the part where I'm agreeing with you? I used different methodology, but arrived at the same conclusion you did. You should be glad of that, because it reinforces your position (on that point, at least) more than it would if I'd merely copied your methodology.
On Earth, people emigrate from POOR countries to RICH countries. How many people emigrate from Australia or USA per year?
Maybe today that's the case, but it can't be universally the case, or how would the Americas have been colonized so thoroughly? Plenty of people left their homes in fairly prosperous countries such as England, France, and Spain to settle the unknown (to them) frontier of the Americas. We do not live in such a colonial age, but people in the Federation in the 23rd-24th century do. Therefore it should be evident that comparisons to the 20th-21st century are ill-chosen. The cultural and economic dynamics are very different.
Besides, there's more than one kind of richness. Those settlers came to the Americas because they sought its material wealth, its wealth of land, its wealth of elbow room, etc. Deneva certainly seems to be a prosperous world; it's a center of mining and shipping, there are valuable crystals found there (according to DS9: "The Sound of Her Voice"), and Kirk calls it one of the most beautiful worlds in the galaxy, suggesting it's a popular destination for tourists and migrants alike. And what we saw of it in "Operation: Annihilate!" certainly looked advanced and prosperous. I don't see any reason to reject the possibility that its immigration rate was high, particularly since, as the numbers clearly show, the annual migration rate
per planet wouldn't need to be particularly large at all.
Furthermore, Deneva was repeatedly described as being inhabited mostly by humans.
Perhaps in O:A, but I don't recall that being specified in the 24th-century fiction.
Well, from those ~100 worlds, only 2-3 are inhabited by humans.
Really? Let's see, you've got at least Earth, Mars, two Alpha Centauri planets, Cestus III, Berengaria VII... and
Star Charts lists a bunch more that are probably mostly human, such as Benecia, Janus VI, Galt, Vega IX, etc.
And despite what tends to be shown onscreen, I refuse to accept that the worlds of the Federation are racially segregated, since that goes against everything the Federation is supposed to stand for. I'm sure there are plenty of humans living on Andoria, Tellar, Rigel, Betazed, Bolarus, Tiburon, etc, and plenty of nonhumans living on Earth, Alpha Centauri, and other "human" worlds --
including Deneva.
And those emigrants have other options besides Deneva to emigrate. They want adventure, to build something new? Then they will go to the frontier colonies, not to Deneva. Deneva is just exchanging a rich, worry-free life (on their initial planet) for more of the same (on Deneva).
Okay, now you're contradicting yourself. First you claimed that people only migrate to rich countries. Now you're saying they'd preferentially migrate to poorer worlds. You can't have it both ways.
Besides, why assume all migrants would have the same motivations? There are countless reasons why people migrate. Yes, there would be plenty of people seeking adventure on the frontier. There would be others drawn to major worlds such as Deneva by their wealth of various sorts: the physical beauty of the world, its culture and art, its robust economic opportunities. Plenty of people relocate for the sake of jobs. If Deneva were a prosperous, growing world, it's only logical that it would reach out and attract new employees and new settlers from all over in order to build its economy. (And yes, even without money in the modern sense, the UFP clearly has an economy; every society does, even if it's a post-scarcity economy.)
