So, I should have posted this before I did it, but I noticed that the application of the census
tag was pretty diverse, in a way which wasn't very helpful. The "tag wiki" summary was not very helpful, and the full explanation of the tag suggests co-tagging with a specific place (e.g. [usa]).
This doesn't seem to be of much use, as tags are meant to help people find questions. I would think that a single specific tag is much more effective than combining tags.
EDIT: I should say, "in this case." I noticed, for example, tags like
language
andjapanese
and can see a case for using those as they are currently. Interest in language is sometimes a flag which transcends specific boundaries. Interest in "census" (especially as minimally-defined in the tag wiki/excerpt) is not really a thing, as best I can tell.
Therefore, I created a new tag, us-census
and wrote a tag wiki entry for it, and changed the tag on most of the extant questions using the census
tag.
Next time I'll post here first but... any objections?
