As the population reaches 7 billion, nobody is quite sure who the 7 billionth person actually is.
Reports from multiple countries have been pouring in claiming that a baby born there is the official 7 billionth, however nobody has been able to agree on who is right. The United Nations designated October 31st as the official day on which the milestone was reached, prompting celebrations and festivities worldwide. It wasn't all good news however, UN chief Ban Ki-moon warned that the growing population would bring with it new challenges as we move on in to the future.
"The United Nations had said that by its best estimates, the world population would reach 7 billion sometime on October 31, but it has said it will not designate a single newborn as the 7-billionth baby, as it did when the global count reached 6 billion in October 1999."
