The CUA is divided into six numbered ''arrondissements'' (administrative sub-districts); it has historically been administered by an elected mayor and associated staff.  Since the 2009 political crisis, in which the Mayor of Antananarivo, Andry Rajoelina, unconstitutionally seized power as head of state, the CUA has been administered by a ''délégation spéciale'' (special delegation) composed of a president and ''de facto'' mayor with the support of two vice presidents, all of whom are appointed by the president. The position of President of the Special Delegation has been held by Ny Hasina Andriamanjato since March 2014.
