| +/- place=city
The largest urban settlement or settlements within the territory.
The place=city tag is used in OpenStreetMap to identify the largest urban settlement or settlements within the territory. These will normally including the national, state and provincial capitals, will often be identified by charter or by official designation and have populations of over 100,000.
For the avoidance of doubt, the use of the city tag within OSM will not always match the official designation of a place as a city. Except in the most rural of locations this tag should not be used for settlements with populations of less than 100,000, or for ones which are smaller than other nearby larger or more important settlements, even if they are official designated to be a city. Consider using place=town for these. The reason for this is to avoid smaller less notable places being promoted excessively within gazetteer searches or being featured inappropriately on wide area maps for the territory.
By way of example, Alameda, within the Bay Area of California (population 76,000) is very close to San Francisco (populations 805,000) and Oakland (population 309,000). This place should probably be tagged as a town even though it is officially a Charter city.
How to Map
The following should ideally all be included for a city:
- name=*: for the name of the city in the primary language for the territory. See Names for guidance on further considerations when setting the name.
- population=*: for the population of the city or metropolitan area.
- wikipedia=*: All cities are likely to have a wikipedia article. Link to the article in the primary language for the place. See wikipedia article for guidance on which language to use.
- Suitable place=suburb nodes to define for the top level named areas of the city and probably also place=neighbourhood for the next tier of named areas.
And also the following where appropriate:
You can also add other useful information as shown in the example. This is useful for searching.
