The deadline to submit applications for the 2016 Summer Olympics was September 13, 2007. The seven cities that submitted bids before that date also met the January 14, 2008 deadline for submission of the first phase questionnaire. 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. If a bid's score was higher than six (IOC's predefined benchmark score), the city was considered highly capable of hosting the Games; otherwise, its chances were very slim. On June 4, 2008, the IOC announced the cities accepted as candidates: Four of the five highest-rated applicants progressed to the next phase as official candidate cities. As stipulated, the IOC granted them the right to use the Olympic rings on their candidature emblem, together with a label identifying each as a Candidate City. The International Olympic Committee went against precedent when it selected Rio de Janeiro over Doha—a city which scored higher yet was eliminated from the field. Doha's weaknesses of a small population, lack of facilities, and Games dates outside of the IOC's desired window may have been too large an obstacle for the IOC to accept. Typically, the IOC selects all the top scoring bids which reach the established minimum benchmark.
