Users colors stats 2010-2021

Revision en3, by Jarekczek, 2022-03-23 23:45:35

I was asked to prepare more stats similar to these charts.

So I present numbers of active users by colors, both absolute and relative, for lifetime of Codeforces.

Absolute users count

Absolute users count

Relative users count

Relative users count

Relative cumulative users count

Relative cumulative users count

Active users means users who:

  • participated in a rated contest in 6 months preceding given date
  • participated in at least 1 rated contest

Measurements are taken every 3 months.

Tooling is contained in this repo. It consists of:

  • java application downloading and caching contests' results, calculating data rows
  • python script generating the plots

Repo also contains the data produced by java application.
