I don't think the Continental United States can maintain a population of 1 billion people and still be wealthy.
How far behind is Latin America again?

It all depends on the starting point. China had something like 120 million people in 1800, and India had something like 250 million (though that included Pakistan, Bangladesh and Burma; the total for modern-day India would probably be a bit less than 200 million), whereas the US had just 5.3 million.Question: How long did it take China to reach a billion, and with what amount of effort?

Best way to do it would be to keep religion a much bigger issue, as religious people have a lot more kids. This could be true for both the US for internal growth, and for Europe, to have a bigger pool of population there wanting to leave. Then have another couple rounds of Napoleonic war style conflicts over the course of the 19th Century for a lot more people wanting to leave Europe.
Socrates: I wouldn't say its meaningfully holding it back from growing a bit at normal-ish rates, I would say that it is holding back the US from tripling its current population. That's an enormous amount of extra mouths to feed, and from where?
And if the US has really low living standards, kiss the floods of people who want to come here goodbye, and say hello to floods who want to leave.
I don't know how India and China maintain it, but starting with a much higher population makes it easier to reach there.
In terms of the capacity to feed people, the EU does pretty fine with a population density four times that of the USA, and it's not even beginning to have issues with food. In fact, it needs to subsidise agriculture to keep farmers in business, because there is an excess of land dedicated to farming output.
] India is about ten times denser - and their population is still surging. Yes, their average incomes are miserable, but this is due to lower technology levels, not food shortages. This later point is demonstrated by the fact that now they have exposure to world markets their growth is surging to catch up with the West, as it is way below equilibrium.
And that's before we even consider the ability to import. Even with much reduced living standards, Americans are many times richer than Asian counterparts. Even if you got to the point of a lack of global capacity to feed the world (which you wouldn't), it would simply mean Chinese peasants would starve, not Americans. Similar things would work out for fuel (which can also be grown, or produced from atoms in the case of nuclear).
Your biggest issue is water - but we have desalinisation for that. Imagine if you tripled your water bill, what real effect would it have on your income?
This is a valid point, but you are exagerrating it's effects. American incomes could drop a lot over the last two hundred years but they'd still be well above European levels - particularly Eastern Europe. Until pretty recently, much of the continent survived on just a few thousand dollars a year - and that's still the case in places like Moldova.
I do agree that the rate coming across would fall, all other things being equal. But they're not all equal in my scenario - a higher birth rate and more wars in Europe would become problems there, making up for any lost effect.
You're underestimating the effect of compounding growth rates. Over a hundred year period, if you start with the same beginning population, and increase the average growth rate from 5% to 7%, you increase the final population more than sixfold. The starting place is a very, very small part of it - that's why there's so many people in the world descended from England, Scotland and Ireland - three very small medieval populations.
