I propose to remove the metropolitan area instance relation from q84. There's also Greater London which is here in wikidata https://m.wikidata.org/wiki/Q23306 and had a population of 8,308,369 in 2012, likely in Osm this can be found or puzzled together from administrative entities (did not check). cheers, Martin _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
