About: List of countries by population in 1989

This is a list of countries by population in 1989, providing an overview of the world population before the fall of the Iron Curtain. While the population data is almost exclusively dated 1989, political developments before the summer of 1990 are taken into account, including Yemeni unification and Namibian independence but not German reunification which was finalised only in October, the breakup of Yugoslavia and dissolution of the Soviet Union took place two years later, and the dissolution of Czechoslovakia three years later.
