This is a tag from the earliest days of OpenStreetMap and has never been formally defined to my knowledge. It is not clear to me whether this is a broad tag for geographic or historical areas with no clear boundary or for distinct administration areas (with specific boundaries) in some countries. If you are using this tag, please add how you are using it here so that we can eventually define it. MikeCollinson 13:27, 21 May 2009 (UTC)
I have used it to describe an area with no specific political signification linked to admin_level, but it is part of an area with admin_level=6: http://www.openstreetmap.org/browse/way/74607493
However, in my view a place=region can also be used for areas that cross admin_level boundaries, even with admin_level=2. An example would be Tirol which is spreads over parts of Austria and Italy. --OSMfan 11:31, 27 August 2010 (BST)
I've used it for The Triangle and The Triad, both of which encompass multiple cities and have ambiguous boundaries, because no other place=* seemed appropriate. Rendering based on population=* would probably seem reasonable to me, but I'm not sure how many non-locals would recognize the names. --Yotann (talk) 21:26, 9 July 2013 (UTC)
I recently encountered a problem due to this tag. See this changeset. Someone used this tag to tag an area without any proper definition and it resulted in being rendered at zooms where even cities weren't rendered. --Arunmozhi (talk) 10:49, 30 May 2014 (UTC)
