Take on 8 billion

It seemed like only yesterday when we had 7 billion people bur overnight the 8 billionth person joined planet earth and Nick Cannon celebrated by firing up a stoagie. Of course we worry about overpopulated but the truth is that with an aging western population we need population growth so that the 40 something's can retire.
But the better question is how the heck did they figure this kid was born in Akron was exactly 8,000,000,000 It's a little too coincidental that they were born in Ohio and not in India or China.
