Population Sizes in Star Trek

Is there any figure on this? How many people live on earth? Humans on colonies? On Vulcan? How many Klingons? etc
 
Nothing canonical.

The closest was an alternate Earth glimpsed briefly in "First Contact" in which there were 9 billion Borg. Currently there are about 7.5 billion Humans on Earth right now...and that number is growing rapidly.

Only in developing nations. Opposite problem in developed world, and also Eastern Europe
 
I've heard some experts say that the rate of population growth worldwide is slowing and expected to top out around 9 million. Even if that's not true I'd think if the exponential growth rate continued we'd hit the world's carrying capacity pretty quickly.
 
Whatever you think the Federation's population is, quadruple it.

Say Earth's population in the 24th Century is 10 billion. This is an extremely low number, given the 9.7 billion projected for 2050, and given that one imagines technology (with or without Trek's replicator) should make a far larger Earth population sustainable, if not our current ecosystem's. Maybe 100 billion per planet.

Over 150 memberworlds in the Federation. Some may only have a few million, some, like the cloning Arcturians, may be closer to that 100 billion number. Let's leave each member's homeworld at 10 billion.

One imagines sophisticated spacefaring civilizations ready for Federation-level membership would have multiple colony worlds. Say 3 powerhouses (at least a billion) and 5 smaller ones (at least 100 million). Again, I think these numbers are low. Older worlds may have many more colonies, and worlds that have been members Federation members for a while have probably doubled their numbers since. And what about all those protectorates, and outposts, and stations in the void, among others?

10 billion x 150 + (150 x ((3 x 1 billion) + (5 x 100 million))) = 2 trillion 25 billion. (2,025,000,000,000).

Even if you think it's too much, cut it in half and you're still at 1 trillion 12.5 billion people. And that's not counting real world issues like copies of people and other net-based lifeforms.

They say in Star Trek 2009 that Vulcan has 6 billion people, which I always thought was very high for Vulcan.
 
I generally think most races are in the 1-3 billion, with some races (Vulcans, Andorians) being around 6 billion, and Humans being the most populous at a few dozen billion. Maybe Klingons and Romulans a little less than Humans.
