UnM49Area Enum
Definition
Namespace: DataStandardizer.Geography
UN M49 area codes for every level of the M49 hierarchy. Each member is named with an underscore followed by the three-digit M49 code, and the member’s underlying value is the numeric M49 area code.
public enum UnM49Area : ushort
Remarks
Unlike UnM49AreaByAlpha2CountryCode and UnM49AreaByAlpha3CountryCode, which represent countries and areas only, this enumeration represents every level of the M49 hierarchy as a member: the world, regions, sub-regions, intermediate regions, and countries or areas.
Per-member metadata is carried by UnM49AreaCodeAttribute and read through UnM49Extensions. Each member’s attribute carries the codes and the names of every level down to and including the level the member itself occupies, so an ancestor’s name is available directly from any member:
UnM49Area._894.GetName("en"); // "Zambia"
UnM49Area._894.GetRegionName("en"); // "Africa"
UnM49Area._894.GetLevel(); // UnM49AreaLevel.CountryOrArea
UnM49Area._894.GetParent(); // UnM49Area._014 (Eastern Africa)
UnM49Area._894.IsWithin(UnM49Area._002); // true (Africa)
Because a code above the country or area level does not identify a country or area, GetCountryOrAreaName returns null for such codes. Use GetName to retrieve the name of whichever level a code occupies.
The M49 hierarchy is sparse. Not every country sits within an intermediate region, and Antarctica (_010) sits directly within the world, so GetParent returns the nearest populated ancestor rather than assuming a fixed depth.
Fields
Members are named _001 through _894, where the digits are the three-digit M49 code. For example _001 is the world, _002 is Africa, _015 is Northern Africa, _014 is Eastern Africa, and _894 is Zambia.
