Pakistan's provinces are divided into districts called "zillas" in local languages (counterpart to a county in US or UK terminology). A "zilla" is further subdivided into "tehsils" (roughly equivalent to a borough in an integrated multi-tier (federated) systemic context, such as the one to be found in Montreal (Canada, 2002) and Birmingham (UK, 2001 announcement) or known as arrondissements in French context. Tehsils may contain town or municipalities. Pakistan's system is the one that applies an integrated federated systemic framework most comprehensively, so far.
