A partido is the second-level administrative subdivision used only in the province of Buenos Aires, Argentina. They are formally considered to be a single administrative unit, usually contain one or more population centers (i.e., towns and cities), and are divided into localidades. The subdivision in partidos in Buenos Aires Province is distinct from all other provinces of Argentina, which call their second-level subdivisions departamento and are further subdivided into distinct municipalities.
Departments (Spanish: departamentos) form the second level of administrative division (below the provinces), and are subdivided into municipalities. They are extended in all of Argentina except for the Province of Buenos Aires and the Autonomous City of Buenos Aires, the national capital, each of which has different administrative arrangements (respectively partidos and comunas).
Except in La Rioja, Mendoza, and San Juan Provinces, departments have no executive authorities or assemblies of their own. However, they serve as territorial constituencies for the election of members of the legislative bodies of most provinces. For example, in Santa Fe Province, each department returns one senator to the provincial senate. In Tucumán Province, on the other hand, where legislators are elected by zone (Capital, East, West) the departments serve only as districts for the organization of certain civil agencies, such as the police or the health system.

Greater Buenos Aires (Spanish: Gran Buenos Aires, GBA), also known as the Buenos Aires Metropolitan Area (Spanish: Área Metropolitana de Buenos Aires, AMBA), refers to the urban agglomeration comprising the Autonomous City of Buenos Aires (CABA), and the adjacent 24 partidos (counties) in the Province of Buenos Aires (together known as "Conurbano"). Thus, it does not constitute a single administrative unit. The conurbation spreads south, west and north of Buenos Aires city. To the east, the River Plate serves as a natural boundary.
The term is also related to other expressions that are not necessarily well defined: the "Buenos Aires conurbation" (Conurbano Bonaerense); the "Greater Buenos Aires Agglomeration" (Aglomerado Gran Buenos Aires); and the "Metropolitan Area of Buenos Aires" (Área Metropolitana Buenos Aires, AMBA).
