World Population

Here's a really interesting stat I ran across today, but one which I would like to expand upon. It deals with the population of the world, its estimates from wayyy in the past, and the estimates 30-40 years into the future.. along with some fairly accurate numbers in between:

The world's population has doubled between:

1181 & 1715 (534 years)... approx. 375 to 750 million

1715 & 1881 (166 years)... approx. 750 to 1500 million (or 1.5 billion)

1881 & 1960 (79 years)... approx. 1.5 to 3 billion

1960 & 1999 (39 years)... approx. 3 to 6 billion

At this rate it will be at 9 billion by about 2038, and will double from 6 billion to 12 billion (gulp, that's 1,200,000,000, or 1.2 trillion) by about 2079 or 2080.
