CityData["name", "property"]

  • The full specification of a city is {"city", "region", "country"}, where "region" is a state, province or other administrative division.
  • Names of cities, regions, and countries are given in standard forms, such as "NewYork", "BritishColumbia" and "UnitedStates".
  • CityData["city"] gives a list of all available cities worldwide that use the name "city", sorted in order of decreasing population.
  • CityData[{"city", "country"}] gives the full specifications for all available cities in the specified country that use the name "city". The results are sorted in order of decreasing population.
  • CityData[{"city", "country"}, "property"] gives the value of "property" for the city with the largest population in the given country that has the specified name.
  • CityData[{"city", "region", "country"}, "property"] gives the value of "property" for the particular city represented by the full city specification {"city", "region", "country"}.
  • If there is more than one city with a given name in a particular region and country, the standard name for that city will contain additional identifying information, such as a county name.
  • CityData[{"city", "ss"}, ...] can be used to specify cities in particular states in the United States, such as {"Springfield", "IL"}.
  • CityData[{All, "region", "country"}] gives a list of all available cities in the specified region of a country, sorted in order of decreasing population.
  • CityData[{Large, "region", "country"}] gives a list of all large cities in the specified region. Large cities are typically defined as having populations above 100,000.
