Seven Billion People

We're slated to hit 7,000,000,000 in 2012.
We hit 6 billion in 1999.
Thirteen years to add a billion.
We hit 1 billion in 1800.
In 1930, 130 years later, we made 2 billion.
(data from the AP)
So between 1930 and 1999 we added 4 billion in 69 years.

Different predictions: http://en.wikipedia.org/wiki/World_population_estimates

But I agree with gavin6942 that your scenario is way too pessimistic. There will be more famines and more wars, but I don't think we'll see anything like the famines or wars of the 20th century in the 21st.

I could go into more detail but LJ comments are limited in length, so I'll make an entry about it later.

I look forward to that post! I do not consider myself a pessimist, more of a realist.....I have been studying on this question for years now and what I notice is that Americans especially do not want to admit that people around the world could starve or die in wars (due to actions of our government!) while we are comfy and fat in front of our large screen televisions.......so if you can dissaude me I am eager to hear your arguments.

Let me know if there's anything I'm wrong about there of course, it's just preliminary.

Excellent find on the chart. It actually makes me wonder -- how do we know what the world population is right now?

Most countries have some form of census. Those that don't probably don't make much of a difference either way, because all the most populous countries have one. So it's not exact but it's probably accurate to within 50 million or so.

I understand. It was just an odd thought. America has allegedly hit 300 million people, but also claims to have 12-20 million undocumented workers. That's a pretty big gap of uncertainty, in one country alone.

Europe, for the most part, has open borders. So their census is hard to judge.

Parts of Africa are still "wild" in some sense.

I wasn't questioning you, but more the establishment. It's interesting how they can pinpoint with such certainty when we hit milestones, when it seems to me they could be days, months or even a year off.

Well....we don't, exactly.....but we have a general idea, within a few million. That is an interesting comparison. Wikipedia rocks!
