A visual presentation of world chess ratings

By Michal Paterek

How many chess players have Elo rating? Where in the world is the highest density of rated players? According to the FIDE rating list there are in the world more than 170,000 people with Elo ratings – the exact number is 170,932. The graphs below show that most rated players are in Europe (72.1%), especially in the western and central part of the continent.

 

In second place is Asia, where is more than 15% of the players reside. On other continents chess is statistically less popular. Third place is South America, North America is fourth. Africa, which is the second continent in terms of population (and area) has only 1897 rated players (1.1%).

The largest number of players with a rating live in Germany (17,499), second place is Russia (16,703) and third Spain (14,364). India (number five), with total of 12,129 number of rated players, has more players than the countries of North America (8,145), South America (9,451), Australia and Oceania (1,331) or Africa (1,897). The highest density of rated players is in western, central and southern Europe. However, the highest average ratings (= average rating of the top ten players) are in Russia, Ukraine and China.

Below are maps containing the list of countries with: the total number of players with rating, number of players per number of inhabitants, per unit of the area and the players with the highest ratings in each country.

Note that you can click on the maps to enlarge them. After that, hovering with
your mouse cursor on the map will reveal the statistics of each individual country.

Maps use a close variant of the Mercator projection. It's not the most accurate projection, but is widely used on the Internet. However, more accurate visualization of the surface can be represented in a real three-dimensional model.

Click on the image for a truly breathtaking mouse-controlled 3D image of the earth:

(Rated players per area unit - 10,000 kilometers square)

The average value of the ratings is approximately 1900. The rating of the player in the middle of the rating table is 1924. Players with a rating greater than 2300 are in the top 5% of all players, and players with a rating greater than 2450 are in the top 1%.

These data visualization can help in the analysis, but the original FIDE table can also be useful. There are a lot of details visible when you click on the country and link "See detailed statistics for country".

The U.S. is an example of a country which is seriously underrated in a study that limits itself to FIDE ratings. The U.S. used the Elo rating system, originated and administered by the U.S. Chess Federation, for many years before Elo ratings were exported to FIDE. The great majority of tournaments in the U.S. are still rated only by the USCF domestic system, and are not reported as FIDE results. (USCF has 80,000 members, a sizeable portion of them tournament players with domestic Elo ratings.) So most U.S. rated players are not in the FIDE data base. In other countries that did not have a rating system before the FIDE ratings were introduced, the FIDE system became THE rating system, and all rated games are FIDE-rated. The result is a very considerable underrating of the number of rated tournament players in the U.S. The same may be said for Britain, which also has its own rating system, and for other countries that have a separate domestic rating structure. So while the study correctly reflects the number of FIDE rated players in each country, that is not the same as the number of rated players (or Elo rated players) in each country, which for some countries could be much greater.

Of course the US is poorly represented. If it was well represented here, this article would not appear on Chessbase.

This website is run by narcissistic liberal morons.

I refer you to their "twin tower sacrifice" joke in the aftermath of 9/11 for which they refused to apologize. Even writing an entire article defending it.

USCF rating is just a local rating system. FIDE ratings is international. If you do not have international rating (elo, FIDE), what kind of player are you? 80 thousand. players with local rating is not an impressive number. It's only 78 players with USCF rating per 1 million inhabitants, assuming that 25,000 players have USCF rating in your country.
Please do not compare your local rating system with international rating system - FIDE, because it is not an article about the local systems but about International Ratings.
