Welsh OSM Stats for OSM Nerds (#2, September 2026)
Forewords
Croeso and welcome to the second edition of Welsh OSM Stats for OSM Nerds! I am stiill working on improving the format and the presentation, so if you have feedback please let me know! Compared to the 1st edition, this edition features changes from August in brackets! Note that numbers fluxate quite a bit from month to month, so the aren’t always the most useful metric. I will look into how to improve this in the future! 💚
North Wales Mapathon Gogledd Cymru

Changesets
A total of 440,755 changes was made in September (increase of 32% since August) spread across 3,003 changesets (decrease of 18%). A total of 304 users made changes in September (decrease of 24%). The biggest reason for the reduction in number of changesets were the reduction in the number of StreetComplete quests that were completed.

Editors (Golygyddion)
| Editor | Number of users | % of changes | % of changesets |
|---|---|---|---|
| iD | 179 | 57.2% | 42.6% |
| JOSM | 56 | 39.7% | 17.7% |
| StreetComplete | 47 | 0.8% | 27.0% |
| Others | 79 | 2.3% | 12.7% |
Golygyddion Cymraeg (Welsh stats)
3 users submited changeset through an editor where the langauge was set to Welsh. The only two editors that had reported Welsh users were iD and StreetComplete. This represented 19.4% of changesets made using iD and 2.96% of changesets made using StreetComplete. JOSM also has Welsh support but no users made changsets with the Welsh locale. I suspect this will change in October though with StreetComplete being made available for IOS.
Users (Defnyddwyr)
304 made changes in Wales in September (decrease of 72). Of these, 75 made their first ever edit in Wales (decrease of 55). Of these 75, 16 made their very first OSM contribution in Wales (decrease of 7).
