Grenada, a tiny nation with a population of a little over 106,000 people may be the Olympic Champion for Rio 2016.

The island nation won just one medal, Kirani James's silver in the men's 400 m dash, but that might be enough to win the "Medals Per Capita" title at Olympics 2016, as calculated by this website.

Bahamas, with two medals, is second on this list, with a medal for every 194,009 people. These two, along with Fiji, are the only countries with populations of under a million persons to win medals at this year's summer Olympics.

While the country with the most number of Olympic medals, the United States, stands 43rd on the list, India, with a medal for every 655, 525, 263 people brings up the rear with a cumulative return of two medals.

China, with a haul of 70 medals, could only make it to 76th, with a medal for every 19,588,857 people.

Weighted medals per capita

In 2008, the New York Times introduced the concept the weighted medal tally, a system in which gold would equal 4, silver, 2 and bronze, 1 medal point.

This gives India a weighted score of 3, while the United States earns a weighted tally of 296, far greater than the next nation, Great Britain with 171, re-asserting the dominance of the US over the rest of the field.

How many people does it take, then, for every weighted medal won by a country?

Tiny Jamaica is unsurprisingly a stand-out performer with six golds to its name, notably three involving the fastest man in the world, Usain Bolt. With a weighted medal tally of 32 and a population just over 2.7 million, Jamaica is third in this category with 85,196 people per weighted medal. Grenada and Bahamas are, naturally, higher.

India brings up the rear once again, with a population of about 437 million people per weighted medal, 402 times that of the US, which sits in 36th place with a figure of one weighted medal for every 1.08 million people or so.

GDP per Weighted Medal

Is GDP, the measure of the size of the economy of a country, directly proportional to tje weighted medal tally? That's true in many cases.

The top five in the weighted medal standings – US, Great Britain, China, Russia and Germany – each have a net GDP in excess of $1500 billion, placing them among the largest countries by GDP.

Unfortunately, India – whose GDP is pretty much the same as Russia – is in 86th and last position among medal winning countries, with a GDP per weighted medal of $616 billion.

The United Arab Emirates ($360 billion per weighted medal) and Austria ($418 billion per weighted medal) stand at 84th and 85th, just ahead of India.

Weighted Medals per 100 Athletes

This is the only category that Grenada doesn't top in, with the honours going to Tajikistan, who won a gold with a contingent of seven. Dilshod Nazarov's performance in the men's Hammer Throw gave them a weighted score of four. So, Tajikistan takes top spot with 57 weighted medals per 100 athletes.

This is a good way of looking at the success of the US Olympic contingent. Although the Americans had the largest contingent with 554, their weighted medal score of 296 means that the US takes second spot on this table with 53 weighted medals per 100 athletes, quite an achievement for such a huge contingent.

Although many athletes have won multiple medals, that does not detract from the fact that the US won 46 golds, one for every 12 athletes it sent to the Games. India would have had to win 10 Olympic Golds with their contingent size of 117 to match or beat the US score.

The Great Britain and China are both in the top 10 in this category. India, with a weighted score of 3, gives the nation a score of two weighted medals per 100 athletes and does not finish dead last this time, lying in 76th position instead.

Cuba, with a comparable contingent size of 120 athletes, receives a weighted score of 28, giving them an average of 23 weighted medals per 100 athletes. Nigeria and Portugal finish last, with one bronze medal to show for 75 member and 92 member contingents respectively.
