Talking of OSM edit activities, what’s about timeserie statistics by Country - Continent ? Pascal Neis osmstats website presents daily perspective over OSM objects edited by country where he added from early 2022 Organized editing.
I thought that we could have some perspective using these timeseries by country. See my diary Trend of OSM Objects Edited with focus on Organized editing where I present a brief analysis from the data I compiled from osmstat (2022-04 to 2023-06).
If you want to make you own analysis using a spreadsheet, you can download the compiled data (csv format) from github.
