Islands District
At the time of the 2010 Census, the regency was divided administratively into ten districts ("kecamatan"). Subsequent to 2010, the Banjak Islands District was divided into two, with a new Western Banjak Islands District ("Kecamatan Pulau Banjak Barat") being carved out of the existing district. The districts are listed below with their areas and populations at the 2010 Census and the 2020 Census.
