[4] The third-largest island in the group, Dullah, on which the city of Tual is located, is no longer within the Regency.

Kei Besar's topography varies between 500 and 800 metres above sea level, and differs from the islands to the west by having a karst formation in the middle of it.

[5] Kei Kecil (also called Nuhuroa) is more low-lying, not exceeding about 100 metres above sea level, and contains much swampland; the regency's nominal capital, Langgur, is situated in the north-east of the island, just across a tiny channel from Tual on Dullah Island, and effectively forms a suburb of the City of Tual.

[1] The table also includes the locations of the district administrative centres, the number of administrative villages in each district (a total of 185 rural desa and 6 urban kelurahan), and its postal code.

The town of Langgur (the Regency's nominal capital) comprises more than half the population of this district.

The second riot that occurred on 12 November killed two people and injured dozens of civilians and two policemen.
