**Apr 16, 2018 2:25 pm**I have heard of Dan Browns book, but I wasn't aware of its premise. If it were possible to reduce the fertility by 2/3 (without the gory details that the film portrays), how long would it take to reduce the population to, say, two billion (assuming the death-rate stays the same)?

Edit

Perhaps a mathematics clever-clogs could do an estimation (using the latest fertility in Hermits link as the starting point)?
