How many people play chess in the world?

An estimated 605 million adults play chess regularly — a figure FIDE (the International Chess Federation) put forward in 2012, extrapolated from a YouGov survey and submitted to the International Olympic Committee. Surveys suggested about 70% of adults have played chess at least once. Of all those players, only around 1.6 million hold an official FIDE rating: the competitive tip of a vast iceberg. Interest surged again after 2020 with online play and streaming.

A short history of chess

The undisputed World Chess Champions (1886–today)

The classical, undisputed lineage runs through 18 champions. (Between 1993 and 2006 the title split into "classical" and FIDE versions; it was reunified in 2006, and Viswanathan Anand became undisputed champion in 2007.)

The average age of a world champion

An original computation from the table above: across the 18 undisputed champions, the average age at first winning the title is about 30 years old. The youngest ever is Gukesh (18, 2024); before him the record stood with Kasparov (22, 1985), later matched by Carlsen (22, 2013). Steinitz was the oldest to first take the crown (50), though the title was new; in the modern era the oldest first-time champions were Botvinnik and Smyslov (36). The champions hail from a dozen countries, with the Soviet Union and Russia by far the most represented.
