If you make it over a hundred year time frame the fact that number of children per family drops as you get wealthier can mean that as the third world got richer they also like parts of the current first world had less the replacement birth rates. So population has dropped. This is not when current projections show that happening but not a major bit of handwaving to move it earlier. You also end up with large numbers over 60 who if they stay will die off over the next 40 years.
