Hi, I have recently noticed that quite an amount of the population tags in the cities/towns/villages nodes have been removed in bulk on different change sets. Is there any particular reason for this, since that tag is widely used when getting our dataset and can't seem any reason for removing data from OSM. If this was done wrongfully, is there a way to revert the changes? Thanks in advance |

I will go through the thread and try to get in touch with the French community to try and figure this out, thanks for the feedback. |
Do you have a few examples of such changesets?
This appears to be one changeset where lots of population tags were removed from the place nodes and added instead on the administrative boundary relations. https://www.openstreetmap.org/changeset/79698989 In general, the population tag would normally be on the place nodes, so this change could break things for a number of data consumers.
It looks like these changeset have been discussed on the talk-fr mailing list starting here: https://lists.openstreetmap.org/pipermail/talk-fr/2020-January/096261.html
It is a long thread (about 40 messages) and I haven't looked through it to see if it specifically explains the move from nodes to relations.
I had a quick further look at that mailing list discussion. I think the issue may be that the available population figures relate to communes rather than villages, so should be associated with the commune boundary rather than for example a place=village node (as there may be inhabitants outside the village).
You may need to make contact with the French community for further details.
