The present population is increasing by approximately 1.7% and I believe the population in 1999 was approximately 5.8 billion therefore at the present rate of growth:-
By 2099 the population will be 5.8 billion X 1.7 = 9.86 billion.
Or 0.0986 born per annum.
5.8 billion / 0.0986 = 58.82 so 59 years.

I'm going to be different and suggest around 2030. The birth rate is rocketing worldwide, people are living longer, and I don't think it likely that a massive war will take place that'll wipe out millions. 2030. Final answer.

I think that Ollie (answerer 3) has thought it out correctly, and the others are badly wrong.
I was going to say 2031 before I saw ollie's answer, so I'll still say it; 2031.
