Does anybody think it goes on this way? There are a couple of arguments against it. The last 50 years have been very special in history. Earth had incredible jumps in healthcare, agriculture and sociology. But the population explodes just in the 3rd world. If people get healthier they tend to have less children. One example: My Father, born 1916 in Hungary, was the 11th of 12, my Mother was the 5th of 7, but it is just my Sister and me both born in the 50ies in Germany.
That's right - health care got better with the introduction of antibiotics and medical techniques discovered during the Second World War, and that began the baby boom. As the population became more healthy, that meant fewer people died off due to various natural maladies and lived longer. This also meant fewer children died, which meant that the population also grew. However, it should be noted that the declinining birth rate in most of the first-world nations is not due to better health care, but rather the fact that the higher standard of living (and the work required to maintain it) means that they're less inclined to have children who they have to support until they're through college or whatever. Back when the children could be put to work for you, more kids were an asset - and they still would be on a colony world, since they could help around the house as it were.
In other words, it's not the better health care that's caused a decline in birth rates - it's more that, in an urbanized society, there's no advantage to having more than two or three kids - and with what you end up paying just to raise one kid to adulthood, it's a liability. In a more rural setting, more kids meant you had more workers handy, or else someone to take care of you and support you with their own work once you grew old - the introduction of pensions and social assistance for seniors has reduced this need somewhat, and combined with the above factors has helped lower the births in most first-world nations. Worse yet, the present-day economic realities of work and the requirements to stay competitive have not helped: look at Japan or anywhere that has a really strong work-ethic and you'll notice that the deathrate is starting to outstrip the birthrate, because everyone of age to reproduce is either pursuing a career, or else their significant other is pursuing a career and isn't home long enough to do the deed.
This poses a huge problem for those nations as, within the next twenty years, a large population of senior citizens will be added to their social welfare nets while there are fewer workers to help maintain them.
It should also be noted that, under the rule of the WEC, Earth's population spread out to at least the Moon - and I suspect Mars, at least given the terraforming dates in the WC Bible - and has grown well beyond the current ten billion, at least to judge by the descriptions of life in the game. Between the slowship colonizations and then the jump-drive colonization that began in 2418 or so, there's definitely more than enough of a population to start shipping out, and if they were able to build slowships, then we know they've got enough of a infrastructure to build jumpships to start sending people to what will become the Inner Worlds. The next wave of colonization will come from those areas, once they gain enough infrastructure and people to start sending across the stars, which means that, several hundred years later (2700), we've enough of a population spread out across five hundred systems to kill off a few billion and still have billions more to have families and get killed later. It's not like they're abandoning their technology so that most of the kids they have die in infancy, and more kids on a colony world would be useful due to the need for them to do work that doesn't involve sitting at a desk.
There's also the influx of new people as a colony becomes more developed, since not everyone's going to want to be a pioneer - so you'll have people being born on Earth that want to live in a less crowded area, but with amenities - an Inner World colony is just the ticket out for such a person, and they'll be able to bring skills that may not be well-represented in the present population, and will also be of an age to reproduce, which means we can also add more children to the colony or have enough of a surplus population to move onto new worlds where they can be true pioneers again.
Given that even an outer colony which had probably been devastated in the first days of the war had two million people (Hanover system) on it, it doesn't seem too far-out to have had that many casualties - it's staggering in our terms, but it's not a civilization-ending sort of thing, especially spread out over 35 years and several hundred systems.
