I mean for instance list of all users and its declared location
(assuming that this is a poor indicator: we tend to sometimes edit in
remote places, declared location may be outdated, etc).

Total nodes may be a good indicator for completeness, while recent
nodes may be useful for assessing the activity of the community. I am
interested on both indicators.

On the other hand, I believe recent nodes may be a misleading
indicator on regions where the DB is quite complete (I am interested
specifically about highway=*) and there is little urbanization
activity. Of course, there is always some corrections to do on any
area, but probably they are statistically negligible compared with a
region which still has lot of unmapped roads.
