Urban Employment Area

[1] It is different from the definition of metropolitan areas defined in census by the Ministry of Internal Affairs and Communications.

The basic principle of UEA is similar to that of the Statistics Bureau definition; a central city and its associated outlying municipalities with certain numbers of commuters.

A UEA with at least 50,000 DID (Densely Inhabited District) population is called Metropolitan Employment Area (大都市雇用圏, Dai-toshi Koyō-ken) or MEA for short in English.

A UEA with at least 10,000 and less than 50,000 DID population is called Micropolitan Employment Area (小都市雇用圏, Shō-toshi Koyō-ken) or McEA for short in English.
