The place key is used to indicate that a particular location is known by a particular name, and to indicate what sort of "place" it is. Place keys exist on single nodes by themselves, to show the center of a "place" and as an aid for rendering a label or as a navigation waypoint. They also can exist on a relation, to additionally show the extent of an area.
A place tag should exist on an OSM object for every significant human settlement (city, town, suburb, etc.) and also for notable unpopulated, named places.
|Mapping populated places as extents is often not verifiable. More detailed discussion of this can be found in Talk:Key:place#Verifiability_of_mapping_populated_places_as_areas.|
You may further define a place by also defining a boundary for it. The best way to do this is by creating a place relation.
If you choose to map a place with a relation, and a previously existing node for the place=* exists, keep tags for the place on that node, and assign it the
waypoint relation, to ensure no information about the place=* is lost, and that that information is easily accessible to machine interpreters.
An encouraged usage until recently was to apply the
place=* tag to areas. The problem is that OSM Areas, by themselves, cannot have associated nodes. Historical experience has shown that relation member nodes are extremely useful (especially for machine data consumers) to help interpret and render place "areas" created in OSM, whether to provide additional information, or for backwards compatibility.
See the place relation for best practices for creating boundary relation shapes.
If you have a way of knowing the population of a place (from a free data source), the population=* tag typically is added to the place. Also useful is the addition of wikidata=*/wikipedia=*. For a standalone node, these tags belong on the node the place tag appears on. In a place relation, this belongs on the node with role
