Here's the picture in quantities, milestones and values.
The 2016 Olympics will be the first held in South America, leaving Africa the only continent never to have hosted the Games.

Rio expects around 10,500 athletes from 206 countries around the world.
7.5 million tickets have been available to catch all the events.
To keep this amount of people fed and watered, the city will produce 11 million meals and provide 34,000 beds.
315 horses will participate in competition, and no less than 25,000 tennis balls will be used.
There is plenty to cheer about on the commercial front, with more than 700 commercial contracts signed with 1,272 suppliers. Officials are also claiming that the sponsorship programme target of US$1.2bn has been met.
The much-publicised security concerns are also reportedly being met with eye-popping figures. Organisers plan to deploy 60,000 security personnel for the Games. The security operation is larger than the 40,000 at the London Games but smaller than the 75,000-strong in Athens - at a time when organisers were worried about terrorism following the 9/11 attacks in New York in 2001. The Rio security operation is expected to cost US$200m. This compares to the 170,000 security personnel employed and US$800m spent on security for the 2014 football World Cup.
In preparation, Rio has already hosted around 40 test events in Deodoro, Copacabana, Maracana and Barra da Tijuca, all locations in the city that will host competitions.
In total, 306 gold medals are up for grabs across 42 sports.
This edition of the Games will see the return of two sports for the first time in around 100 years - rugby returns 92 years after its last appearance, and golf is also back 112 years later.
More than 130,000 people will work directly on Rio 2016.
At the Paralympic Games, to be held after the end of the Olympics, medals are also given to the guides of blind athletes in triathlons and athletics.
Worryingly for a country in its deepest recession for 100 years, the original budget of 28.8 billion reais for the Games has increased to over 37 billion reais.
The organisers say there are 6.6 million tickets available for the Games in total, with just over 50% of the Olympic tickets and only 15% of the Paralympic tickets having been sold. Those figures are much lower than for London at the same point in time. However, Rio organisers point out that Brazilians do everything at the last minute.
As well as the International Olympic Committee sponsorship strata of 11 worldwide Olympic partners, such as Coca-Cola, McDonald's, Samsung and Visa, there are six official sponsors including Nissan and Brazilian bank Bradesco.
Coca-Cola's current Olympic sponsorship runs until the 2020 Games and is estimated to be worth in the region of £33.7m for each four-year Games cycle.
There are also ten official supporters, including EY, Cisco and Latam Airlines.
