(11 ;districts), Iloilo(7 ;districts), and Samal (3 ;districts: Babak, Kaputian and Peñaplata). Some cities such as Caloocan, Manila and Pasay even have an intermediate level between the district and barangay levels, called a zone. However, geographic districts and zones are not political units; there are no elected city government officials in these city-specific administrative levels. Rather they only serve to make city planning and other administrative tasks easier and more convenient.
