[1] Kabupaten Selayar is the Regency, covering 1,357 km2 with a population of about 139,145 in mid 2022.
To the east lies Pulau (Island) Kalaotoa and Pulau Karompa Lompo (in Sulawesi Tenggara province), and to the west lies Kepulauan Sabalana (the Sabalana Islands).
The strata of Selayar Island are all sedimentary rocks: coraline limestone, occasionally sandstone; everywhere, except in the north and north-west, covered by a fertile soil.
The watershed is a chain running throughout the island from N. to S., reaching in Bontona Haru 5840 ft.,\ and sloping steeply to the east coast.
They speak the Makassar language and are for the most part nominally Muslims (though many non-Muslim customs survive) and support themselves by agriculture, fishing, seafaring, trade, the preparation of salt (on the south coast) and weaving.
