gasp! what an interesting question!. probably somewhere in between 80-100 years... i would have to say because if you take into account all the people born at this precise moment and the ones who will be born within the next 9 months..... umm it would take a lifetime beginning from now.

Well, if the average life expectancy of the most developed of countries is about 75 to 80 years, the world would be mostly empty in about 80 years from now but if you give it 90 years, then it will probably be completely empty.
If certain dictators around the world are allowed to continue with nuclear weapons programmes though, it will probably be a whole lot sooner.

that question is impossible to answer. You don't know how long the last person will live, could be 80 years, 120 years, 30 years. You never know. Also, somethings on the planet reproduce themselves so just because man and woman stop producing, life would still produce.

Probably about 90 years. The world would be empty when the last person dies.
So although we could be around for upto 120 years, there'd be no-one left to look after the oldest people, so I think they'd have trouble living beyond 90.
Of course, the world wouldn't be empty - just no humans.

In reality it would only take approximately 40-50 years.
Whilst we have a life span of approx 80-90 years, this assumes that we still have people in all the needed functions of society, food manufacture, power, medicine etc.
As they die off with no replacements and the things which we need to achieve an 80 year span dissapear, the life span would come crashing down along with society. Our final years would be spent in a state of near starvation and sickness.

According to the film "Children of Men," itself based on a novel by, IIRC, P D James, about fifty years - as long as the span between the last girl being born and her reaching menopause.
When the last girl born on Earth can no longer produce babies, that's it for the human species. The last humans would age and eventually die, and presumably the last grave digger would end up lying in a bed with nobody to bury him ... and that's it.
God, what a depressing thought.

The last person alive would be a woman and she would be from a very rural but fertile area where she has spent her whole life living off the land. How old? Probably into her hundreds, if neglected nuclear power stations didn't finish us all off a whole lot earlier.
Then it would be the turn of the great apes, let us hope they make a better job of it.

A century, give or take. But it won't happen. People are constantly reproducing. I don't plan to have children myself but I seem to be the exception in my age bracket. Seems to be the thing to do at a certain stage in life. "Guess I better get married & start breeding since everyone else is doing it." I'm the only single female homeowner on my suburban street. Surrounded by couples with 2.2 kids and a dog. I live with 2 cats, my guitar, paint & canvas. I produce works of art and write songs. Those are my babies!

You are forgetting about clones. Humans would not accept the fact that males and females had stopped producing. It will only be empty of humans on Judgement Day.
