Selection of the host city is done by postal voting by the members of the IOC four to five years prior to the tournament, in which the IOC members vote between candidate cities which have submitted bids.
Through analysis of the questionnaires, the IOC gave a weighted-average score to each city based on the scores obtained in each of the questionnaire's eleven themes: political and social support, general infrastructure, sports venues, Olympic Village, environment, accommodation, transport, security, past experience, finance, and legacy.
These submit a more extensive bid book and are subject to additional evaluation, which is presented to the IOC members.
IOC members from a candidate NOC may not vote in any round while their country remains in the election.
It lists the national Olympic committee, the city, and the games for which failed, and successful bid were submitted.
