What follows is a list of the cities that have bid to host any of the Summer and Winter Olympics. Olympics have been chosen to be held in 50 cities (including repeats) since its "rebirth", twice in Eastern Europe, 5 times in East Asia, once in Central America, and the remainder in Western nations. No African, South American, Central Asian, Middle Eastern or South Asian nation has ever been chosen as host for the Olympics.
Typically, the decision is made at an IOC Session approximately seven years prior to the games; for example the 2012 Summer Olympics were awarded to London on July 6, 2005. The decision for the 2016 Summer Olympics will be made at the IOC Session in Copenhagen on October 2, 2009.
