1) Locate last year's post. A year ago it was FIDE Rating List - January 2021 (8 January 2021).
2) Access FIDE Ratings Download (fide.com) and download the file that is described something like this:-
STANDARD
TXT format (14 Jan 2022, Sz: 8.33 MB)
3) Load the file into the database that stretches back to 1971 and compare it to recent years:-
2022: >377K players; >228K marked inactive
2021: >362K players; >174K marked inactive
2020: >354K players; >181K marked inactive
[...]
4) Produce a sequence of queries to derive the following charts. It shows one new federation since January 2021, plus two views of increases in the number of players per federation. The chart on the right is restricted to federations with 100 players or more at the start of 2021.
5) Create some additional posts (optional), then hibernate until the following year. Last year I wrote one additional post:-
- 2021-01-15: FIDE Rating List - Inactive Players
...The numbers under point '(3)' above show that the count of inactive players in 2022 increased three times more than the count of active players. Looks like I should revisit the subject of inactive players.
