....Thanks Brian. Um, I was really interested in annual figures - like Richard Haddrell used to publish (but without the breakdown detail) and to answer the questions: were there fewer active OTB players in 2022 than in 2019 and, if yes, how much smaller was the population? The monthly figures you've provided give some indication but a player will play in some months but not others (typically summer months). I appreciate we now have a monthly rating system.
There are reasons that these numbers are not 100%, but curating them for e.g. players who are only there by way of one default, does not justify the effort. The 2022 numbers might increase by a few as late results arrive.
In 2019, 13,947 played standard play with 12,271 equivalent in 2022; 7,004 are found in both lists. If we look at all lists combined (obviously online and OTB blitz were not available for rating in 2019) the corresponding numbers are 22,694/19,156/8,763.
As a rule of thumb there is c15% turnover each year, lapses heavily weighted to new players. This implies people in both lists 3 years apart should be over 60%.
Thanks Brian. 12,271 standard play players in 2022 vs. 13,947 in 2019 (=88%) strikes me as not bad. But just 7,004 in both lists (an attrition rate of 49.8%) is, I think, not so good (as you say, the annual attrition rate is not great and this has long been so but the three-year number for 2019 -> 2022 seems especially big). The combined online and OTB numbers look good but am I reading it correctly that the combined number was lower in 2022 than in 2019 - if, yes, what happened to the (pandemic + Queen's Gambit) online boom?
FWIW, I have figures (from grading lists made available to results officers) for the grading years 2009/10 to 2018/19. These show, for example:
- players with a category A-E grade playing 1+ standard or rapid games ranging from 11,627 (2009/10) to 15,049 (2018/19)
- players playing 1+ standard or rapid games (regardless of whether player has a grade) ranging from 15,037 (2009/10) to 21,946 (2018/19)
- average annual % of leavers (for years 2010/11 to 2018/19, with leavers defined as having a grade for the previous yr but not the current yr) - 19.2%
- average annual % of joiners (for years 2010/11 to 2018/19, with joiners defined as having a grade for the current yr but not the previous yr) - 22.3%.
