July 11th is Day of The Five Billion

The Day of Five Billion, 11 July 1987, was designated by the United Nations Population Fund as the approximate day on which world population reached five billion. Matej Gašpar from Zagreb, Croatia (then SR Croatia, SFR Yugoslavia), was chosen as the symbolic 5-billionth person concurrently alive on Earth. The honor went to Zagreb because the 1987 Summer Universiade was taking place in the city at the time.
