An Adjusted Ranking of 2016 Rio Olympic Games

 Total Medal Tally 
Sports are all about figures, numbers that are measured with the most precise timers, and scores carefully tallied, and ranked. One number seems to get all the limelight is the IOC's official Total Medal Tally or Table (TMT). Perhaps because this figure gives the overall performance of a country in the Games rather than just on any one specific sport.

Total Medal Table

To put it in another way, the individual medal belongs to the athlete, and the TMT belongs to the nation. Therefore, this TMT ranking is in no way reflect the individual athlete. Just the ability of nations in producing athlete.

Some would say that the Olympic Games isn't a level playing field with more medals going to the bigger and richer nations of the world. Is it possible to rank the sporting performance of countries by removing factors like population and wealth out of the equation to give a ranking that's fairer?

I think we can. Let's try the following for size.

 Weighted Total Medals Points (WTMP) 
For the purpose of establishing Table A to Table D in this article, I don't want to make use of only gold medals a country gets because that would be unfair to countries whose have lots of silvers and bronzes but few or no golds. On the other hand, i don't want to using only IOC's TMT (that gives a single total number) because these sets of numbers treat golds, silvers and bronzes equally, which they're clearly not.

Rank Country Gold Silver Bronze

Clearly, country B performs much better than country A. As it stands, only golds count. Silvers and bronzes count for nothing. Why bother handing out these medals then?

To solve these 2 issues, we need to derive a Weighted Total Medal Points (WTMP) system from the official TMT values. Instead of treating all medals with equal values, a weighting of 1 is assigned to bronze, 2 to silver and 3 to gold. In this system, higher WTMP values rank higher.

For example, Australia has 8 golds, 11 silvers and 10 bronzes. Instead of treating them the same and gives them a TMT of 29, WTMP will yield the following result,

WTMP (for Australia) = (8 * 3) + (11 * 2) + 10 = 56 points

Apply it to our fictional countries A and B, we get a fairer ranking,

WTMP (for A) = (2 * 3) + (1 * 2) + 2 = 10 points
WTMP (for B) = (1 * 3) + (7 * 2) + 4 = 21 points

Country B has a higher WTMP, so it should rank higher.  That's better, isn't it? It's not perfect, but it's better. I say it's not perfect because getting a perfect weighting factor for gold, silver and bronzes is tricky. It's less than perfect, but it's better than terrible when literally no amount of silvers and bronzes could equal a single gold. That doesn't sound too sporty.

  Population   (Source: List by United Nations (2016))
If country A has a population of 100 million and wins 5 gold medals while country B has a population of 50 million and wins 5 gold medals, all other things being equal, country B should rank higher than country A. This is because if country A has a greater population, it has a greater potential pool of people to draw from. A tiny country would be disadvantaged in the TMT ranking. Hence, the ranking needs to take the country's population into consideration.

To get this figure, we divide WTMP by population in million with the highest number ranks at the top.

Using the examples of country A and country B, their WTMP Per Million of Population is 0.05 and 0.10 respectively.

While IOC's official TMT tends to rank countries with large population higher, the ranking in this table tends to favour countries with smaller population.

South Korea is not only the highest rank in this table. It's the only country with 3 digits WTMP. It's not even a communist country. Impressive. Its communist cousin North Korea, however, ranks 50.

Note, India has a value of 0.00. This is caused by rounding. I think Indian would know that because they're very good at maths. If there's a Olympic Games for maths competition, they probably get a lot of medals.

  GDP Per Capita   (Source: List by United Nations (2015))
When it comes to gauge the prosperity of a country, it's misleading to look at GDP alone. One needs to look at GDP per capita for a more meaningful measure. India has a GDP about 3 times larger than Switzerland, but you wouldn't say India is a more prosperous country than Switzerland. Or has more money to train athlete (the Swiss probably spend more money in the Winter Games).

If country A has a GDP Per Capita of 10,000 dollars and wins 5 gold medals while country B has a GDP of 5,000 dollars and wins 5 gold medals, all other things being equal, country B should rank higher than country A. This is because if country A has a bigger GDP Per Capita, meaning it has more money to train more athlete than country B.

To get this ranking figure, we divide WTMP by GDP Per Capita. The bigger numbers rank higher.

Using the examples of country A and country B, their WTMP by GDP Per Capita is 0.0005 and 0.001 respectively.

In this measure, the table favours poorer countries (countries with lower GDP per capita). In this case, North Korea ranks 2nd while its south cousins ranks 36. Both China and Russia have considerable lower GDP per capita than that of USA, hence their higher rankings.

 Collective Athlete Performance 
If country A has an Olympic team of 150 athlete and wins 5 gold medals while country B has a Olympic team of 100 athlete and wins 5 gold medals, all other things being equal, country B should rank higher. It's quality over quantity.

Czech Republic (asked to be renamed to Czechia) ranks high in this and Table A. Impressive result. China stumbled in Rio, dropping its TMT from #2 to #3 spot. And for the 1st time, there's no Chinese women players in the badminton finals where they dominate the sport for a long while. They didn't do so well in gymnastics either. Overall, the Chinese athlete didn't perform as well as previously.

 Final Aldjusted Ranking 
The ranking in the 3 tables above all have its distortions. Table A rankings favour countries with small population. Table B rankings favour poor countries. Table C rankings favour countries with smaller team. So we should combine the rankings from these 3 tables above to gain an average together to produce a more all-around, balanced ranking in the table below.

To obtain this table is quite straight forward. We simply sum up the rankings of the 3 tables above and order them from the lowest to the highest to obtain Table D below.

Jamaica and Azerbaijan rank the highest in this Final Adjusted Ranking. Usain Bolt, who represents Jamaica is like a one-man Olympic team or Michael Phelps of Jamaica.

Even though i created these tables, i'm somewhat surprise that Great Britain ended up ranks #3. Their performance in Rio is exceptional.

Russia (#5) and USA (#6) also rank quite high.

To rank higher than #10 in Table D, China would have to get many more medals than USA.

China doesn't rank as high in Table D as the official TMT suggests (which is #3). China has a lot of room for improvement as they're latecomer who didn't join the Olympic Games until 1984 after decades of isolation like North Korea today (actually North Korean is competing in the Games and doing quite well. You can say that before 1980 China was more isolated than North Korea today. And not just in Olympic Games. But in every other way). The Chinese participated in only 9 Summer Games comparing to, say Great Britain, who attended in all 28 Summer Games since the start of the modern Olympic movement in 1896. Having said that, in the #25 spot, they rank higher than Germany(#26), Japan(#31), or Australia (#33).

Brazil, the host country, rank #46, sits about the middle of the table.

Sometimes, having just a few high-performing athlete can make a difference to the rankings of a country, USA has Michael Phelps, Jamaica has Usain Bolt. In the Sydney 2000 Games, swimmers Ian Thorpe, Grant Hackett and Michael Klim, propelled Australia to #4 place in the TMT. Only in 1956 Melbourne Summer Games that Australia ranked higher in the TMT. Aussies won a lot of medals in swimming then as well.

These impressive athletes distort (the word is used in the same positive sense as the word "disrupt" when describing technology) the ranking of TMT of countries. The most awarded athlete can win more medals than 100 countries (in Rio there are 116 countries that receive no medals).

These multiple medal holders are tended to be restricted to sports of swimming and athletics. Some sports have no chance of winning more than 2 medals for a country (one for men and one for women). Not all sports are created equal for TMT (or WTMTP for that matter).

This Final Adjusted Ranking is far from perfect. Instead of just looking at IOC official TMT, which could be misleading because it doesn't take factors such as population, GDP per capita, and the number of athlete a country sent to the Games into considerations.

One thing that can improve this final ranking is applying different weightings to the ranking of Table A to C before producing the final Table D. But i'm in no position to come up with the correct weightings (i don't know if it could be done).

Olympic Games Rings Mascot and national flags

While it isn't perfect, this Adjusted Ranking have made allowances for all these factors, and give a ranking that's more indicative of a country's sporting performance overall. It's more balanced, fair and nuanced about the sporting performance of countries.

Think of this as just an alternative way of looking at the IOC's official TMT ranking.

Please let me know if you detect any errors in my figures in the comment section. I'll correct them accordingly.
